Looking lovely in the garden this week is the amazing native small tree, Aesculus parviflora var. serotina ‘Rogers’. Despite this amazing plant being native only in Alabama, it thrives in gardens well north of Chicago. This named selection was discovered in the early 1960s in the yard of University of Illinois professor Donald Rogers, and named because of its more floriferous nature, as well as its more pendulous flower spikes.
Here are a few of the many buckeyes that are looking good at JLBG this spring.
Aesculus pavia is native from Illinois south to Texas and east to Florida. Hardiness is Zone 4-8.
The European Aesculus hippocastanum has thrived for us, despite most sources claiming we are too hot in the summer. Aesculus ‘Hampton Court Gold’ emerges with ghostly yellow foliage for an amazing spring show.
Aesculus x carnea is a hybrid of the European Aesculus hippocastanum and the American Aesculus pavia. This cross was first discovered in Europe in 1812. It is quite stunning in our garden as you can see. Hardiness is Zone 5-8.
The dwarf form of Aesculus glabra only occurs in a small region of Northern Alabama/Georgia. Mature size is 5-6′ tall. Hardiness is Zone 5-9.
Aesculus sylvatica is one of our oldest buckeye specimens in the garden. This species is native from Virginia to Alabama. Hardiness is Zone 6b-8b.
Aesculus sylvatica ‘Sylvan Glow’ is Jeremy Schmidt’s discovery of an amazing seedling of Aesculus sylvatica that emerges rosy red, then changes to orange, before aging to green for the summer. When it gets a bit larger, we will try to propagate this so we can share.
We saw this amazingly colored buckeye (Aesculus pavia) on a recent visit to the NC Arboretum in Asheville. I’ve seen countless individuals of this species, both in the wild and in gardens and have never seen a color like this. We have encouraged them to get this grafted and introduced.
In 2019, our research staffers were botanizing in Montgomery County, NC, when Jeremy stumbled on this painted buckeye (Aesculus sylvatica) seedling with new pink growth. In the past, we have not had good luck transplanting seedling aesculus, but thankfully this one survived nicely and two years later, it looked great this spring as the new foliage emerged. When it gets larger, we’ll share scions with grafters so we can make this more widely available.
