The following is a guest blog post from Chris Tidrick a gardener, writer and photographer.
Although we’re only a short way into the summer calendar, I have a good idea which plants are going to be the highlights in my gardens. Summer perennials are lush with foliage and starting to bloom, while the annuals planted in containers and garden beds no longer resemble those tiny plants I purchased in flats just a few weeks ago. There’s so much competing for attention in the summer landscape, it often takes the unique plant or combination of plants to truly grab our attention.
This year, a handful of new plants and a couple of garden veterans are stealing the show in my garden.
I grow a lot of coleus (Solenostemon), but the one variety that stands out is ‘Twist and Twirl’. True to its name, its burgundy, yellow, and green, deeply lobed foliage appears to dance up the main stem. More upright and narrow than most coleus, ‘Twist and Twirl’ makes an excellent choice for a vertical element in containers. I have found that it combines best with other burgundy and green coleus, as the bright yellow isn’t the most complementary color with other hues.
Heuchera has taken garden centers by storm in the past few years, but I have to admit that I still waver when asked my opinion on this diverse group of foliage perennials. Perhaps I haven’t given them the proper growing conditions, but most Heuchera I’ve planted seem to simply survive rather than flourish in my garden. I’d slowly been giving up on them, until planted H. ‘Cherry Cola’, a cultivar whose new growth emerges a deep cherry red and slowly fades to a darker brown-red as it ages. When backlit, the plant appears to have glowing embers under the foliage. The foliage color, combined with an above average vigor, definitely places ‘Cherry Cola’ on the short list of attention grabbers this summer.
Helenium ‘Mardi Gras’
From Rudbeckia to Leucanthemum and many genus in between, the choices for summer-flowering, daisy-type flowers seem endless. One plant that is often overlooked is Helenium, or Helen’s flower. A number of cultivars are available, ranging from yellow to orange to red. In my garden, ‘Mardi Gras’ is the cultivar of choice. Standing 30-36 inches tall, it is covered in yellow-orange blooms from June through September.
I’ve also been enamored this summer by ‘Black and Blue’, an annual salvia (S. gauranitica). The true blue petals of ‘Black and Blue’, which resemble Cardinal Flower (Lobelia cardinalis) in form if not color, emerge from a nearly black calyx attached to the stem. In full bloom, the flowers of ‘Black and Blue’ appear to be tiny pennants run up along a ship’s mast. The foliage is green and indistinct, but forms a solid base below these outstanding flowers.
I’ve never been that attracted to yarrow (Achillea), with its weedy foliage and tendency to fade in the summer heat and overwinter poorly during our Midwestern winters. But as I was browsing a clearance table at a garden center last fall, the name ‘Strawberry Seduction’ and a two dollar price tag convinced me to give it a try. So far, it’s been worth far more in my garden. Planted at the base of a large ‘Jackmanii’ clematis, my small clump of ’Strawberry Seduction’ manages to catch my eye every time I walk through the garden.
Any discussion of the attention grabbers in the early summer garden has to include Hemerocallis. I grow nearly 30 different varieties of daylilies in my garden. While my collection focuses heavily on red culivars, including ’Angel Fire’, ‘Ivory Edges’, and ‘Christmas Carol’, there is one I wouldn’t do without: H. ‘Kwanso’. A close, yet cultivated, relative of the much disparaged “ditch lily” H. fulva, ‘Kwanso’ commands attention with its double-petaled orange flowers and vigorous (almost aggressive) growth habit. While many of my other Hemerocallis specimens may get overlooked at first glance, ‘Kwanso’ in full bloom is undeniably a starring member of my garden.
While I’d be remiss to ignore ‘Jackmanii’ clematis that forms the focal point of my front border, ’Jackmanii’ is so well known that it seems redundant to give it more attention. Besides, another clematis in my garden may actually be outperforming ‘Jackmanii’ this year. ‘Rouge Cardinal’ is finally coming into its own after growing on the corner of my home for several years, is covered with dark red-purple, velvet-textured blooms from June through July. After the petals fade, the seed heads that remain are beautiful in their own right.
Often plants form an attention-grabbing combination in the garden. In this container that grows near the end of our driveway, Calibrachoa Cabaret ‘Hot Pink’ and Pelargonium ‘Happy Thought’ (zonal geranium) combine to form a trailing base below a dark pink tropical Hibiscus. The yellow variegation in the Pelargonium foliage offsets the orange-red flowers and forms a clear transition between the solid green foliage of the Calibrachoa and Hibiscus.
Sometimes breaking the rules of gardening can lead to a unique plant combination. While putting my containers together, I had three leftover plants: Lobelia ‘Crystal Palace’, Impatiens Tempo ‘Cancun’ and a small division of a variegated Hosta. While the light needs of these plants are on opposite ends of the spectrum, I decided to push the growing conditions for all the plants involved because I loved the combination of the blue and salmon, with a slight interruption of the yellow variegation in the Hosta.
Those are just a few of the attention grabbers growing in my garden. Please feel free to use the comment feature to share those plants and plant combinations that are starring in your summer garden. Please join me at my blog, From the Soil, on Facebook, or on Twitter.
