Descriptions usually list it as 5' tall. Ours is always at least 8' tall with no particular encouragement. It looks like a cross between a lilac and an astilbe on steroids and it is in bloom for about two months. Customers assume it is a shrub, but it's a perennial and as such needs to be cut back in the fall, quite a project.
Another successful plant this summer is 'red romaine' lettuce.
I bought heirloom seeds and was pleased with the rich burgundy color. It brightened up the salads and was a nice garnish as well.
Clematis 'Madame Julia Correvon (above) has always done well for me. It has smaller red flowers.
I also like to use clematis (here Jackmanii) for bouquets. This arrangement also has cupids dart (Catananche caerulea), annual bachelor buttons and tall ageratum.
I rely on lavatera for cut flowers.
I put a few coleus and one perilla (above left) together in a pot to add color to the perennial display gardens. I have been a bit disappointed with coleus 'red head' (lower right), as I had visions of it becoming a bright red for the entire summer. It is more of a muted red. But coleus Florida City Yalaha (above right) is a bright winner.
'Fresh Look' celosia (above) is easy to grow from seed and is splashy in the garden. Here I have planted it with 'Lemon Gem' marigolds, which have completely stopped blooming and are non-performers for the time being. I'm not sure why they are on strike.
I always grow amaranthus tricolor ('Joseph's Coat') because I enjoy its tropical look.
Amaranthus Tricolor
Here's another amaranthus that has lost its tag. It came highly recommended from either Fedco or Johnnies. It certainly is a performer, but tends to overwhelm the garden. I do, however, now think it might be fun to have a garden with just amaranthus varieties, as there are so many different types and they are all on the wild side. Next year?
I often suggest to my customers that they think about foliage contrast for the impression of color, since perennials, with a few exceptions, do not bloom all summer. Ligularia 'Britt-Marie Crawford' has dark maroon foliage and does fine in full sun. Here it is planted next to 'Sun Power' hosta.
Another nice foliage plant is heliopsis 'Lorraine Sunshine.' The foliage holds its variegation (many plants revert back to green) and it is particularly lovely when in bloom.
We have actually started to sell a few mums, which is a good thing since they are budding up early. And I am already ordering plants and seeds for next year.
