Tropical Hydrangea is probably not a very good common name given the fact this plant is not related to Hydrangea at all. However, the flowers strikingly, do resemble the temperate species. I am referring to Dombeya wallichii. About a month ago I wrote about its cousin, Dombeya burgessiae ‘Seminole’. Dombeya wallichii also attracts an abundance of honeybees and is blooming now, but it is a more substantial speciman. It is tree like and can reach 12-15 feet with numerous clusters of light pink flowers which hang down in a spectacular ball. The flowering period is much shorter than ‘Seminole’ but very showy none the less.
Richard Lyons Nursery currently has this plant in stock.
