Buckeyes are the first tree to leaf out in the spring, which is an adaptation to living in the understory. They leaf out in early to mid April, and when the temperatures drop close to 20°F, it does not affect the leaves. The yellow-green flowers are present ... in early May. Its sharp and rather large buds elongate displaying a bright salmon color, which burst open to reveal a five-fingered leaf. It is our most shade-tolerant tree and will leaf scorch in full sun. Does best in good garden soil with plenty of moisture. It is not a good street tree or good for compacted soil of new subdivisions. The 1-inch diameter fruit is called a buckeye due to its resemblance to a deer’s eye.
