Pink buckeye represents a naturally occurring hybrid form of red and painted buckeyes found in the southern U.S. When I first started growing different buckeyes, I noticed quite a bit of difference in the seed strains I was able to obtain. This one was a hard one to get ahold of at the time and when I grew them out there was more variation in the progeny than I expected. A few of the plants had more of a red tinge to the flowers. One plant only grew 2 feet tall in 10 years and flowers red. Others grew to 15 ft. tall with a strong apical dominance and looks a little bit like the yellow buckeye. The reason for this variation is due to the collections I was getting them from. Not a big deal. Today many of the plants I have are essentially a red buckeye form but growing more vigorously with good leaf retention. Today there are many of these nice cultivated selections found in the nursery trade some of which are patented. This is a good seed strain to use to develop new varieties if you wish. I think the beauty of it from seed is the dwarfish trees with the dense flowering. Although it is uncertain what use the seeds could be, the tree is definitely should be direct seeded into these mixed hedgerow plantings with dense spacings with both evergreens and deciduous trees as pink buckeye appears to be quite shade tolerant.
Further use as a street tree is not a bad idea too. But I think the size would have to be considered as these might be too small to be considered between the sidewalk and street tree. On the other hand, it is a hybrid swarm worth developing further from seed and one way to get buckeye back on the menu in our urban spaces.

Ease of Cultivation |
A good direct seed shrub-small tree. Nuts are perishable so plant as soon as possible. Seeds can sprout without dormancy but vary depending on the tree and seed source. Tolerable to shade and seem ok as an understory plant under oaks and walnuts. |
