The illustrated growing guide
Red Buckeye
Aesculus pavia
Family Sapindaceae
Est. zones 4-8

The hummingbird tree — its scarlet flower spikes open precisely when ruby-throats arrive from migration, a lifeline of nectar shaped for them. A well-behaved small native for the woodland edge or part-shade yard, with bold tropical-looking leaves. Note the glossy buckeye nuts are toxic (they're not the edible chestnut), so plant thoughtfully around animals.
