The asters have been blooming prolifically this fall, probably due to the mild weather and frequent rains we have had. While we have many species of asters on our grounds, the newest additions are a hybrid type called ‘Thunderdome’, introduced in 2023 by Intrinsic Perennials. Read on to learn about this new aster, its origin story and the potential uses in the garden.
North East Meets Midwest
New England aster, as seen in the range maps below, is prevalent throughout its namesake region and upper midwest. Aromatic aster is much more common in the Great Plains. This regional difference shows up in their growing preferences, which is an important factor in determining which species is best in different garden situations. New England aster thrives in slightly wetter, richer soils and aromatic aster can handle the drier soil and hotter temps. ‘Thunderdome’ combines the compact habit and drought tolerance of A. oblongifolius but the deeper purple color of A. novae angliae.
Happy Hybrid
I am often a skeptic of some of the newly introduced hybrid native plants. Too often they are short-lived, overhyped, and rarely deliver on their promises. And researchers are still unsure about whether hybrids and cultivars of natives offer the same ecological services as their parent plants. But I am happy to report that this aster has preformed better than expected in our gardens. Planted just last fall, they matured quickly and bloomed their first year. Not as tall and gangly as New England aster, I am very much appreciating the improved habit. The bloom period has been quite long, and the flowers continue to hold their color.
It has also been attracting lots of attention from insects, and below are just a few of the recent visitors to this particular aster:
Aster ‘Thunderdome’ will continue to be evaluated in our gardens for its ornamental and ecological merits. You can find it blooming now on the west side of the HUB, just north of the greenhouse. I have high hopes for this lovely plant, and hope to see more of it used as we continue to learn about its ornamental potential. It is available for purchase at our biannual FloraKansas events, along with both parent plants and many other native and adaptable aster species from our region.
