Begonia sinensis (ex: Hinkley’s Heronswood) – This is a rare hardy begonia. It has returned annually for more than a decade at the time of this writing and continues to do so as the colony slowly expands in USDA zone 5b. The extensive bloom period begins mid to late summer overlapping with Begonia grandis which blooms later in the season. The typical light pink begonia flowers are held from arching pedicels above pale golden-green leaves that glow in one of our open shade woodland gardens. It is late to sprout in spring, not until June in northeastern Connecticut, so please remember where you have planted it. Though Dan Hinkley's colony achieved 14 to 18 inches in height ours has remained shorter. Site Begonia sinensis in open shade to part sun planted in fertile draining soil. Will arrive pruned back if ordered in autumn. It may be wise for northern gardeners to plant in spring. Cutting grown or from seed.
