All About Grasses….Fall’s Beautiful Accents

447958288_a68914b8b3_b

This has been a sad week in the garden….things are slowly fading away.

Which makes me even more happy that I added several new grasses this year.

When the flowers loose color is when you really start to notice ornamental grasses.

I think one of the keys is they need contrast, this is an excellent example.

The turning leaves and evergreens are stunning.

Of course I love them in the summer for movement.

But this time of year, wow…. you cant help but notice them.

I love all the colors we are seeing in new varieties.  I have been adding several new varieties this past month to my beds.

The main thing I want to stress is….

DO NOT DIVIDE OR  CUT BACK YOUR GRASSES IN THE FALL!

I have made this mistake several times, and every clump died.

Wait till spring to divide and wait till new green growth shows up in the spring to cut last years dead off.  I have killed three pampas grasses by cutting them back too soon!

Wait!!!  And read below for more info………

Ornamental grasses are one of the most interesting and exciting groups of plants to be introduced to the landscape market in the past few years. The availability of a large number of species and cultivars makes these plants very versatile with many potential uses in the landscape. The diversity of grasses has also led to many questions concerning the proper selection and use of ornamental grasses. The following information should assist the first time gardener as well as the experienced landscaper in the selection and use of ornamental grasses.

Types of Ornamental Grasses

The term “ornamental grass” is one of those catch-all phrases used to describe not only true grasses but related “grasslike” plants as well. True grasses are in the plant family, Poaceae, while the grasslikes generally fall into one of two plant families: the rushes, which represent the plant family Juncaceae, or the sedges, which represent the Cyperaceae family. All three plant families contain plants adapted to a wide variety of environments and planting conditions. Within each of these plant families one will find individual species adapted to a wide variety of landscape sites (ie wet or dry, sun or shade, hot or cold climates, or any combination thereof). Growth habits range from low ground covers to intermediate shrub-like plants to very tall hedge-like plants. Ornamental grasses are very dynamic; the size, shape, texture and color of grass will change with every season.

Characteristics to Consider

The first characteristic to consider is if the plant is an annual or perennial. A perennial grass will live for many years while an annual grass will only last one season and will die after flowering or it may be killed when exposed to freezing temperatures. Other characteristics to consider when making your grass selections include knowing if the foliage is winter hardy (evergreen) or not (deciduous) growth form, mature size, foliage color, and time of flowering. Much of this information should be available from catalog descriptions.

Winter Characteristics

The winter appearance of an ornamental grass will differ with the winter hardiness of the foliage. In terms of landscape design, evergreen grasses function similarly to evergreen shrubs while deciduous grasses may function similarly to herbaceous perennials. For many gardeners, the winter character of deciduous ornamental grasses is much more important than the spring and summer foliage or flowers. The mature flowers of grasses may remain intact through the winter or they may shatter. Regardless, these dead, dry features add tremendous interest to the winter garden when contrasted with evergreen plants or structures such as walls or fences. The dried foliage of deciduous grasses creates sound as it expands and contracts in response to changes in temperature or moisture while interaction with wind creates movement in the garden. For these reasons pruning of the dead foliage and inflorescences is not recommended until growth resumes in the early spring.

The growth form and mature size will influence how an ornamental grass should be used in the landscape. Ornamental grasses can be characterized as either clump forming or creeping. Clump forming grasses, also called bunch grass, grow in compact tufts, the width at the base slowly increasing over time. Mountain oats (Chasmanthium latifolium is an example of a clump forming grass (Figures 1 and 2). Creeping grasses are also called running or spreading grasses and spread by above-ground stems called stolons or underground stems called rhizomes. 'Feesey's Form' ribbon grass (Phalaris arundinaceae 'Feesey's Form') is an example of a creeping grass (Figures 3 and 4). Grasses that spread by stolons or rhizomes form roots along these stems, making many of them difficult to maintain within a confined area. Be sure to select the growth form best suited to your garden site.

 

The mature size of a grass should be used as a guide to determine where it should be placed in the garden. We will consider three arbitrary size groupings, short, medium and tall, to provide examples of how grasses can be used. The distinctions between these groups may vary according to gardeners' perceptions of height and growing conditions. In particular, water and nutrient availability will influence plant size. An important consideration to remember is that although the mature size of the grass is important in selection and placement in the garden, a majority of our grasses are dynamic and do not remain the same height throughout the growing season because of pruning of deciduous foliage or flowering characteristics.

Use of Ornamental Grasses

Short Grasses

Short grasses can be used in small groups for a massing effect or in large groups as a living ground cover. Small clumping grasses such as dwarf selections of silver grass or fountain grass (Figure 5) provide an excellent border between plant beds and walkways while small spreading grasses such as ribbon grass make an excellent ground cover. These plants also make good accent plants among other short annual or perennial species. The weeping effect of grass leaves over the edges of pots and planters softens and hides container edges, so don't forget to consider short grasses as candidates for mixed planters or individual pots.

Medium Grasses

Medium grasses can also be used as accents among shrubs or herbaceous perennials or annuals. The shrubs serve as the permanent vertical elements of the planting design while the height and shape of the grasses will vary with the season. Medium grasses may also be used to define areas within the landscape that do not require a solid screen. An example would be a hedge of zebra grass used as a wind block near a seating area. In the early spring the plants are only a few inches tall and will not effect the spring and summer breezes. As the plants grow to a height of 4 to 5 feet by fall they provide fall and winter wind protection. Other medium grass selections include muhly grass (Figure 6), which may be used in mass plantings or as ground cover or leather leaf sedge, which can be used as an accent plant within plantings of annuals such as wax begonia.

Tall Grasses

Tall grasses provide a strong vertical element in the garden. Tall grasses with arching leaf tips can also be used to help soften the harsh vertical lines of structures. Evergreen grasses such as pampas grass can be used to divide the garden into sections or as a transitional plant between a tall hedge and shorter shrubs or perennials. Other tall grasses such as many of the Japanese silver grasses (Figure 7) also work well in the mixed shrub and perennial borders. Early in the season these plants do not dominate this type of planting because of their short stature. As the season progresses into the hot summer, they grow and become a more dominant element. During the fall months, when little else is flowering or drawing attention, a grass like 'Burgundy Giant' fountain grass with its burgundy foliage and rose purple flowers will take center stage.

Evergreen vs. Deciduous

Once growth form and size have been considered, determine if the grass is deciduous or evergreen. This may not be an easy process since many grasses behave differently in different climates. Grasses are classified as warm season or cool season. Warm season grasses are active in the warmer months and tend to go dormant in the winter. Dormant warm season grasses may remain green or the foliage may freeze, die and remain intact until pruned. Cool season grasses are active in the cooler months and are more likely to remain evergreen during the winter. A hard freeze may effect even “evergreen” grasses by damaging the foliage but when warmer conditions return new foliage will usually quickly regrow. Grasses for which the foliage dies in the winter months and remain dormant until the weather warms in the spring are considered deciduous.

Managing Ornamental Grasses in the Landscape

Ornamental grasses, once established, are relatively easy to manage in the landscape because of their minimal fertility, irrigation, and pruning needs. Maintenance considerations may differ depending on local rainfall patterns, native soil texture and nutrient holding capacity of the planting site.

Watering

Irrigation may not be necessary for ornamental grasses once they are established in the landscape. In many areas of Florida rainfall is sufficient for most ornamental grasses, particularly those native to the state. After planting, grasses should be watered frequently like a containerized ornamental with the irrigation applied directly to the root ball. After several weeks, the roots of the grass plant should extend beyond the root ball into the surrounding soil. At this point the plant will normally require irrigation only during extremely dry periods. Most grasses should be irrigated with a drip type irrigation system, which will keep the foliage and flowers dry and reduce the potential for leaf diseases.

Fertilizing

Grasses should obtain sufficient nutrients from the soil if the basic soil fertility recommendations from a soil test are followed. A minimal nitrogen application of 1 lb. of N/1000 ft2 per year is more than sufficient to meet the nitrogen requirements of most grasses. Beyond these basic recommendations, no additional application of fertilizer nutrients should be necessary to promote growth of healthy foliage or flowering. In fact, excessive application of fertilizer nutrients will result in weak, floppy growth of foliage and weak flowering stems that will not stand up to even mild winds. Timing of fertilizer applications should correspond to periods preceding rapid foliar growth of the plants.

Pruning

Pruning of ornamental grasses should be done in late winter or early spring, just prior to new shoot growth. Many of the ornamental grasses have spectacular winter characteristics that should be preserved through the winter months. In north and central Florida, gardeners may target the months of February and March as appropriate times to prune ornamental grasses. South Florida gardeners may wish to cut back or trim ornamental grasses in January or February prior to new growth.

For deciduous grasses, such as Miscanthus, the old foliage may be completely removed within inches of the soil. For evergreen grasses, such as muhly grass, the ragged, dead tips of leaves can be removed to neaten the appearance of the plant. Many evergreen grasses recover quickly from a heavier pruning. Old flower stalks and seed heads may be removed any time they no longer have a neat appearance.

Dividing

Propagation of ornamental grasses is relatively easy and can be done at the time of pruning. Clumping grasses may be dug, divided into several pieces, and replanted. Rapid regrowth will immediately follow. Divisions of creeping grasses may be done also at this time and planted in a container or new location. Division of ornamental grasses is not a requirement for sustained landscape performance but many Pennisetum, Miscanthus, and Panicum may exhibit less vigor as they become older. Many times this is a result of the buildup of the dead aboveground parts accumulating over time. Simple division and replanting is an easy way to rejuvenate these older plants. Named cultivars of ornamental grasses should only be propagated by division because seedlings from these plants may express the broader characteristics of the species rather than the specific desirable characteristics of the named cultivar. Grasses can be easily started by sowing seeds in flats or pots in early spring in an area with bright light. Seedling growth is usually rapid and the seedlings may be transplanted directly to containers or the garden.

Here are some of my favorites in my Zone 6 Indiana Garden…..

Picture 021

Karley Rose  Fountain Grass….. My very favorite….

image

Zebra grass….I like the stripes!

Karl Forester grass, with it’s heavy sense seed heads. 

I also grow maiden grass and variegated Japanese grasses here with no problems.

The only ones that have not over wintered was pink and white pampas grasses.

I have seen them in near here doing fine, but I had three die this spring.

Everyone have a safe and Happy Halloween!

Make sure you check out the landscapes before you ring the doorbells….lol!

Out and About Indiana….

Picture 110

It was fall break with the girls this weekend….a four day weekend. :)

Picture 030

We headed to Turkey Run State Park, about 30 minutes North of Terre Haute.

Picture 032

We stayed one night at the inn.  It is set in the woods and is surrounded by very mature plantings.

Picture 053

I especially liked this statue there.

3090620831_671bcc9739_b

Turkey Run is known for Sugar Creek…but it was too high and cold to canoe.

3053736223_003a9f9d4e_b

And miles of trails with waterfalls and cliffs to explore.

Picture 065

On Sunday we enjoyed downtown Indy.

Picture 066

Since we live in such a small town, it is always fun to see the skyscrapers.

A favorite was Circle Center Mall…..the biggest they had ever been to.

It was big sister’s 10th birthday, so she got to pick out most of her own presents.

She is a very spoiled girl….she got her ears pierced and a cell phone from us…plus countless things we “had to have” this weekend.

Picture 109

It was nice to get away, the leaves we’re really pretty.  We drove home through Brown County/Bloomington area and stayed a second night there.  It is always beautiful.  But they are fading fast I’m afraid.  Enjoy it while we can!

These picture are not the best, my setting we’re off and I could not tell till I downloaded them.

Happy Gardening…..Brooke

New Driveway Beds…What I’ve Been Doing!

Picture 054

This project has been on my “to do” list for over 3 years now….the driveway!

Picture 050

I have looked in all my old files for a before picture and I guess I don’t have one.  It was kind of an eyesore, we would weed-eat around.   “It had potential”…but too far to water and it had to be “tough”.  The only thing that was there before was the irises.  And they did very well, so I divided them and added three boxwoods, the middle one is a golden variety, but it is hard to tell in the picture.  I am planning on adding more perennials and extending the bed in this area, but for now….it is looking good to me.

Picture 056

There is a good clump of zebra grass behind the light  pole.  It has a security light on it, and I am glad we have it.  It has been dark when the girls get on the bus in the morning….Indiana’s time is always messed up!  It’s dark here will 7:30 AM!

There are a mix of just about every kind of evergreens and two pink spireas.

Picture 047

My favorite of the new things is a “sunny” yellow knock-out rose.

Picture 048

It is a pretty yellow-cream double and it has a light scent.

Picture 049

The pyramidal yew is about the only tall shrub on this side.  I plan on adding blue spruces and pines later to the left of this.

Picture 056

Here you can see the irises too….  I will add more color in the spring.

Picture 046

Little junipers and pines look really good with the boulders.  These, like all my rocks we’re dug up when we did our walk out basement.  They would have been a fortune to have brought in, I love them…..but our contractor did not!

Picture 043

This is the opposite side….more evergreens.

Picture 042

This area and the fire-pit have a more rustic landscape design, but at least there will be something to look at all winter.

Picture 051 

I have to admit, I really do not like “basic shrubbery and evergreens” but there are just places we need them.  I tried to pick interesting varieties at least.  When I see other gardens I sometimes think I need more variety, mine really looks bad to me when everything dies back.

Picture 044

This is a pink bush honeysuckle and a few mums.  I got almost all of these plants on clearance here locally.  In all I added over 40 new evergreens and shrubs  both at this area and around my house.   Most I gave around $3.00 a piece for and bought smaller plants.  They will get big soon enough and I will have to get the pruners out!

My goal is a bit of color in the winter….and a few branches to cut for some arrangement fillers.   But that’s a long way off I think!

End of Season Blooms…A Fond Farewell…..

Picture 006

I ventured out into the cold this morning for a few shots in the garden.

(The Fairy Rose)

Picture 002

It has been unseasonably cold here with a few hard freezes.

(Shasta Daisy)

Picture 036

So I thought I had better take a few pics while there is still something pretty to enjoy.

(Limelight Hydrangea)

Picture 035

I really must admit as much as I love fall.

(Dahlia)

Picture 038

It just breaks my heart to see the flowers leaving.

(Obedient Plant)

Picture 024

I am just not a cold weather person.

(Countrytime Rose)

Picture 005

But I am enjoying some 2nd time blooms like Candytuft that had reseeded.

Picture 030

And Sweet Alyssum that has really took off again, I pulled this all out in August b/c it got leggy and shook the blooms, now it is EVERYWHERE….but I love it.

Picture 016

One last daylily to enjoy.

Picture 022

A pretty salvia from seed…love this color.

Picture 018

Look at how beautiful all the strawberry plants are under my steps.   It started with one plant 2 years ago, and they just keep on coming.  I think they are pretty and even though they need more sun, they are a good groundcover.

Picture 017

Little baby hollyhocks and moss!  I love moss and try to place it on the rocks if I can.  It is so pretty, these seeds are heirloom…. I can’t wait to see the blooms next summer.

Picture 010

But this is my favorite thing from seed right now….. Purple Coneflower, planted in April this year.

Picture 013

I have it in several spots, you can see the frost just about got them Saturday night.

I guess the new thing in fall wreaths is to use the centers of these with the petals taken off in arrangements.  I can see that working, but I am in no hurry to pick them nor do I want to stop them from seeding.

Picture 019

The grasses are all doing really good right now, but this feather is my favorite.

Picture 040

Some blue cornflower has popped up again.

Picture 033

And the hostas are doing well, this one has a sweet scent.

Picture 034

And the Boston ferns still look great, which is a miracle….because I never water them.

Picture 029

The butterfly garden is showing it’s fall colors….

Picture 066

The big hostas are dying back, I will miss them so.

Picture 067

But my hyacinth bean vine has tons of seed for me to use next year…. I have 40 already!

Picture 071

Which just gets me excited for next year….Happy Fall Y’all!

(A cute sign I picked up at a yard sale!)

Picture 062

From our house to yours….Happy Gardening….Brooke
