Need a late spring/summer blooming temperate forest shrub? This native could be the ticket. Two varieties of this species spread out the bloom period for a potential month and a half, and the plant doesn’t care if the highs are in the seventies, or like today, in the nineties.
In the wild, Bottlebrush Buckeye is found primarily in Alabama and Georgia, but it is now grown in Zones 4-8. The plant pictured is the earlier blooming “species” variety that was at peak bloom last week, when it was pummeled by 4+inches of rain in one day, and it still looks as pictured. Soon the second variety, often sold as var. Serotina, will begin to bloom, and will continue blooming into July. We have one of those as well, and it will bloom into July. Northern gardeners have reported later periods of bloom stretching into August.
A huge population of wild var. Serotina plants are growing just about three miles from here, south of Garden City, right along the edges of US Highway 31. Every few years Alabama Power will cut them down to the ground under the power line that runs to Blount Springs, which somehow or other rejuvenates the plants. Within in a few years the blooms will be spectacular, with limestone boulders interspersed with hundred foot long colonies of plants, and blooms hanging out over the road from steep hillsides. Unfortunately this section of highway is known for some spectacular wrecks, though they have never been attributed to drivers rubbernecking the plants.
