Building Garden Interest with Texture

DSCN4963The elements of texture and form, shape and garden occupy my thoughts more and more as I add plants and the garden matures. I really like the textures of plants in the shade bed, but the main bed along my patio is starting to look a bit messy. I’m not sure if it’s because the dwarf blue spruce is so slow to grow unlike the grasses, which are getting very big and therefore the balance is off, or because there are so many spillers in the garden and that’s creating some visual chaos. Either way, I’m exploring the themes of texture, balance and color as I consider moving things around next year.WWW Cacophony3I never thought much about texture until I started gardening. Texture creates interest and interplay among plants. In the world of texture, contrast seems to be key, and there are a couple of ways to achieve texture in garden design.

  1. Placing plants with contrasting leaf shapes near each other.
  2. Placing plants with contrasting bloom shapes near each other.

Properly combine fine, medium and coarsely textured plants in the garden and you’ll get visual interest. Too much texture and you can end up with visual chaos. And there’s both tactile and visual textures to consider.Yikes. (When I initially started planning my gardens, this overwhelmed me, not to mention other considerations of size, shape and color.)DSCN4968Most plants have medium texture. I typically use coarse and fine textured plants as a great way to achieve accents.Then I try and spice things up through complementary or contrasting colors of plants. The finely textured leaves from Russian sage (Perovskia atriplicifolia) complement the medium-textured leaves of rudbeckia. The bloom shapes from all three are small, medium and large. And the grayish-green Russian sage also provides a color contrast to the green of the other plants. DSCN4976Proper texture pairings provide lots of interest and result in pleasing vignettes. This is not as simple as you might imagine. It’s probably one reason why gardeners move plants around year after year.

Balance combines with texture and creates unity. I like the balance in my shade bed, achieved by repeating astilbe, hosta, fern and Japanese forest grass (Hakonechloa) throughout its linear shape. The  astilbe’s bottle brush-shaped bloom lends coarse texture in contrast to the smooth leaves of the Japanese forest grass. Visual interest if further achieved through contrasts in color and leaf shape.

In the combination below a trifecta of color, shape and texture unite to create a pleasing vignette at the Missouri Botanical Garden. The coarse brown center of the yellow rudbeckia and the soft, finely textured brown plume from an ornamental millet pair up, as do the daisy-like petal shape and the contrasting shape of the brown plume. And last but not least, brown and yellow make a complementing color contrast. bes and milletWith so many varieties, succulents are a great way to add texture to a container. Soft rosette shapes combine with coarse texture, and the grayish hues of all the plants create color harmony in a succulent display at the Toronto Botanical Garden last summer. I love the fuzzy texture of the echeveria next to the crassula princess pine.DSCN2996 (1280x960)How important is texture in your garden? And what plants are you incorporating for textural variety?

Hot for Hostas

DSCN4664Hostas have so many of the elements I look for in a plant. Easy to care for. Can be divided. Comes in lots of varieties, both big and small. But truth be told, I’ve not always been a big fan of them–even though they have been in every garden I have planted. You’d be hard pressed to find St. Louis garden that doesn’t incorporate hostas into its design. These are workhorse plants in this part of the Midwest and they go well in many applications.

hosta by rosesMy fondness for hostas is growing. This plant is an essential element to my shade garden and I enjoy looking at them every day. I love the hosta in the photo above (taken in May) but will probably move it next year. Even though it is encased by the oakleave hydrangea, which filters the sunlight, it gets too much sun and by July it looks like its about to burn up. There are “sun loving” hostas but don’t be fooled, this is plant really a shade lover.

DSCN0734

Too much sun? Not enough water? Both I’m afraid. I got wise and moved any hosta in this area and, yes, upped the water.

So why the growing affection for this hardy perennial? As they say in real estate parlance: Location, location, location. That’s right, I think I have finally found the right spot for them. And, I like the mix of perennials they’re planted with. Shape and texture, the keys to any garden, really stand out in a shade garden. Some have larger leaves than others and they are mingling in the bed with the tall, delicate shapes of fern, deeped lobed leaves of heuchera, spikey and brightly colored Japanese forest grass and the serrated leaves of astilbe, whose plume is to die for.

DSCN4401

The blue hue of “Frances Williams” (center left) stands out against all the other green in the garden bed. This variety is a welcome contrast to the bright green Japanese forest grass (hakonechloa).

Hostas like water and Frances Williams is no exception.Its leaves become wider as it matures.

Moisture is another important consideration when placing hostas. I have learned the hard way that they do not do well in dry shade. Mine are mostly planted in a bed with a bunch of other moisture lovers, mainly fern and astilbe. They also like slightly acidic soil which is in abundance in my garden.

Hosta’s flower is nothing to speak of so its appeal is its foliage. I’ve planted hostas whose foliage have a spectrum of hues from citron with greenish/blue streaking to blue with creamy yellow edging and deeper green with white edging.

 

DSCN4602

I’d like to share with you the names of the hosta varieties I have in the yard, but I don’t know them. Many of the plants in my garden are from the local area garden club sales, friends gardens, or were in the yard when I moved in, and they didn’t come with a tag describing their variety. Because they grow so well in our USDA Zone 6a climate, I am a big fan of dividing hostas and placing them throughout the garden beds.

In the Swing of Spring

Here’s a quick peek at the goings on in my Arch City backyard. So happy it’s spring!

Japanese Maple April (2) (960x1280)

Bloodgood Japanese maple (Acer palmatum) starts to leaf.

Tulips April (1280x960)

Pretty pink tulips in bloom. Fond reminders of a family trip to the Netherlands last fall.

Clematis April (960x1280)

Clematis begins its winding growth. Transplanted in the fall from a container, it seems to like its new spot. This is the second year for this plant and I think I’m falling in love! 🙂

Japanese Forest Grass (1280x960)

Bright chartreuse and green leaves of Japanese forest grass (Hakonechloa macra) after a rain.

Rain barrel and rhodos (960x1280)

Pretty pink and purple rhododendron in full bloom. Note the rain barrel in the back. More about that in a coming post.

Penstemon April (960x1280)

Husker Red penstemon (Penstemon digitalis) bursting forth. This is one of my favorites. I love the purple/green leaves with red veining. Before too long it will be in bloom.

Astilbe April (1280x960)

Hairy stemmed astilbe (Astilbe chinensis) are planted near the Japanese forest grass. But there are other signs of life in my shade garden: pointy tips of hosta emerging, curly coral bell (heuchera) leaves, rosy colored  tips of Solomon seal (polygonatum biflorum), lemon-lime creeping Jenny (lysimachia nummularia), and soon, ferns, glorious elegant ferns.

VegTrug April 1 (1280x960)

The great seed planting experiment shows signs of life: cool season greens and brocolli.

Rain Gauge April (960x1280)

Spring rainfall, cool night time temperatures and warmer days make possible all of the above.

Ah Yes Moments in 2015

DSCN3119 (768x1024)If you’re like me, it’s easy to look in the rear view mirror and lament what went wrong during the previous season and think about all the “could ofs,” “should ofs” and “only ifs” as I plan for the next.

Last year was not the best year for my back yard garden. The tremendous amount of rain we had in June took a toll on the way the plants performed, and it seemed like there was never enough time to accomplish what needed to be done. But, there were plenty of highlights to year 4 in my gardens. Here are few:

1. Improving the Entrance into the Yard. Visitors who came through the gate in 2014 were met with a raised bed supported by rotting railroad ties whose 5-inch nail spikes stuck out. The step down into the yard was deep, making it awkward and potentially dangerous. I said goodbye to the ties and installed interlocking stone that coordinates with the stamped concrete patio. An added step provides a more natural distance down into the yard.

The addition of a step off of the raised area, makes stepping into the yard easier.

2. Attending the Garden Bloggers Fling in Toronto. Okay, this is technically not in my garden, but I’ll extol the virtues of expanding your network to anyone who enjoys gardening. First, who doesn’t like a garden tour? The Fling was a 3-day-plus extravaganza of garden tours. This experience allowed me to learn first-hand from other gardeners–hobbyists to the pros–what they are doing in their gardens and public spaces. It was an outstanding way to expand my thoughts on gardening and meet many of the people behind the blogs I so enjoy. The Fling has me thinking more seriously about natural resources conservation, starting a vegetable garden, composting and the joys of connecting with those who share a common passion.

3. Installing a new bed along the south fence. Outside of raising children, nothing teaches patience like gardening. I may be planning and planting for four-season beauty, but each garden season (spring/summer/fall) is just one cycle and it took me several cycles to finally get to the south fence. I enjoyed sitting on the patio looking at this lovely, lovely shade garden.

Freshly mulched, the south fence bed in June. Japanese forest grass, heuchera various fern, hosta, creeping Jenny, solomon seal and astilbe provided lots to look at all season.

4. Edging the Beds. What a difference a seemingly small task makes in giving a garden bed a finished look. I considered installing metal edging, but instead opted for the back labor (someone else’s, as I hired this job out) to cut a nice edge around my main garden beds.

3. Plant division. Want to save a little money? Get more of a plant you just love, love, love? Fill in a space in the garden bed? Share with a good friend? Improve your garden design and color balance? Two words: Plant division.

First purchased from the Webster Groves Women’s Garden Club plant sale, these purple coneflower have been divided and added throughout the gardens. Self-seeders, they quickly and easily multiply.

In Search of the Elusive Super-Blooming Garden Plant

I don’t know my diploids from my haploids or my tetraploids. But I do appreciate a perennial that blooms like crazy. And when it comes to garden favorites such as clematis, lavender, hosta, tall garden phlox and oh, so more it’s all about the tetraploid. That’s breeder speak for hybridizing plants that Super Bloom. And while long-lasting, seemingly never-ending blooming plants at one time were elusive, thanks to the smarts of breeders gardeners are able to sit on their patios and enjoy their favorite hydrangea in bloom all that much longer.

Abby Elliott

Sugar Creek Gardens Nursery owner Abby Lapides Elliott offers a show and tell of some of her favorite Super Plants.

I learned about this and more on a warm, clear-skied Thursday evening when I attended my first after-work (actually after- dentist) gardening talk at one of my local nurseries. I receive e-newsletters from a few of my favorite local plant purveyors. They are usually quite informative, including information on the local weather conditions and its impact on plant diseases and planting times, the specialty plants they are carrying and educational sessions they are hosting on a variety of topics of interest to the home gardener–everything from pollinators to planting under trees to natives to today’s talk on Super Plants. It’s smart marketing for local garden centers to differentiate themselves from the big box stores by inviting special guest speakers to host fun/educational events that bring their customers together. I had not been to one of these special events before because the nurseries I visit most often host their events either during the day when I am at work or at 5:30, when, foremost in my mind is getting home or completing post-work errands. Today was different. After a less than enjoyable dental procedure I decided to stop in at Sugar Creek Gardens Nursery to treat myself. Lo and behold they were about to begin a session on Super Blooms, hosted by Sugar Creek’s owner Abby Lapides Elliott. Abby didn’t go into too much scientific depth but did illustrate her informative talk by explaining that modern breeding using tetraploids (four times the haploid number of chromosomes in the cell nucleus) means that gardeners now have access to plants that boast not just a long-lasting blooms, but plants with beneficial and favorite traits combined that, for example, come in an amazing color, can tolerate geographic conditions, resist diseases, have larger or smaller blooms or foliage, and more.  Think hydrangeas that can be incorporated into a mixed garden more easily because they grow only 2 to 3 feet tall versus the more traditional size of 6-plus feet; agastache that is resistant to deer, rabbits and drought; bubblegum pink phlox with giant blooms and resistant to powdery mildew; or native heuchera crossed with traits that result in a variety that is more tolerant to heat and humidity. Of course, there is no free lunch. I came away from this short, 30-minute session armed not just with more knowledge but several plants for the garden beds. And given their improved traits, I’m not complaining. Purchases

Progress Report: Turning Dreams into Reality

concrete planter

Astilbe circle the base of the concrete stand. I placed the armillary sphere on top as a last-minute gesture. My original plan is to put a container oozing with plant atop the stand. But I do kind of like this look.

It’s just after 6 p.m. My fingernails are filthy, my shoes are muddied (and in the garage), I have hat hair, my lower back is talking to me, and the shade garden bed that I dreamed about all winter has begun to take shape.

It was a very good day in the garden.

The long view of the bed, looking toward the top of the bed. There’s plenty of room remaining for the caladium bulbs on order and Japanese forest grass. And as time goes by, I think I will add more heuchera to the front.

This was a day of moving plants from one bed to another, checking the layout I painstakingly mapped out in the midst of winter–desperate for a spring day like today–and making modifications on the fly. My daughter Louise and I hoisted a concrete plant stand and moved it to the middle of the bed, which could have something to do with the backache. Here is what has gone into this fence-line shade bed that is anchored at the top by a maple tree and curves at the bottom into the wet “problem zone” of the yard:

  • Astilbe Chinensis “Visions,” featuring a raspberry red plum.
  • Ostrich fern (Matteuccia Matteuccia). Placed in the back of the bed in front of the fence because they can grow five and a half feet tall.
  • Hosta “Frances William.” This is one forgiving plant because I have moved it three times in three years and it seems unfazed.
  • Heuchera “Plum Royal” and “Marvelous Marble.” The Ruffled Lime I planted last year have not reappeared.
  • Several variegated Solomon’s seal (polygonatum biflorum). My friend Mary generously allowed me
  • to dig up several transplants from her yard early in the week and I was able to get it in before the torrential rain this past week. It has doubled in height in the one week it has been in the bed.

Still to come: Caladium “White Queen,” Japanese forest grass (Hakonechloa macra) “Aureola”, creeping jenny. And mulch, lots of mulch.

Dear readers, how does your garden grow?
