The weather has been quite mild this summer, with relatively few days topping 90 F (32 C), but the color in the garden is certainly heating up. Our big patch of Canna ‘Flaming Kabobs’ is almost blinding in the sun, but it has a lot of competition. Here are some of the hot flowers in the garden this week.
1. Canna indica “Musifolia” (Indian Shot)
I grew this from seed received as Canna musifolia, but Kew says that name is a later synonym of the widespread and variable species C. indica. The mother plant was >8 feet tall, but this seedling is blooming at barely 3 feet tall. I only recently transplanted it out of a pot, so I am hoping that it will grow bigger in the ground. Many of the modern Canna hybrids have flowers that are big, shapeless blobs of color, so I really like the small, orchid-like flowers on this plant. The red-edged foliage is also lovely, but unfortunately Japanese beetles like it too. The common name of this species comes from the resemblance of its hard, round seeds to shotgun pellets or musket balls.
2. Tithonia rotundifolia (Mexican Sunflower)
We don’t grow many annuals, but who can resist this color? We started a batch of these guys from seed under lights and planted them out about a month ago.
3. Achillea “Paprika”
This is a very common perennial available from most garden centers in the summer, but it is well worth growing nevertheless. It has a tendency to flop over, but the stems soon start growing upwards again. It is often sold as a cultivar of Achillea millefolium (common yarrow) but is actually derived from the Galaxy series of hybrids which originate from crosses of A. millefolium and A. x Taygetea
4. Echinacea ‘Sombrero Sangrita’
Some of the modern Echinacea hybrids are really impressive. This cultivar has intense red flowers on compact, upright stems, worlds away from the dusty purple and rangy stems of wild type E. purpurea.
5. Lilum ‘Forever Susan’
This Asiatic Lily is a lot shorter than I expected; it’s less than 2 feet tall. We got a bag of bulbs this spring, and I’m glad I planted them at the front of the flowerbeds. They’d never be seen behind tall Cannas or Crinums.
6. Sinningia tubiflora
Do we need to cool off a little? Sinningia tubiflora–a gesneriad species from northern Argentina, Paraguay, and Uruguay–has surprisingly large white flowers. Their tubular shape and lemony fragrance in the evening surely point to pollination by moths. The underground tubers, like those of several other Sinningia species and hybrids, are winter hardy in the NC piedmont.
