East Asian tree flowering in July–August, when most sources are over; its broad white clusters give abundant nectar and pollen.
Bee-bee tree is a medium-sized tree native to Korea and northern China; in Europe it is planted by beekeepers and municipalities especially to close the late summer forage gap. Its broad, flat, white flower clusters consist of many small flowers and strongly attract many insects, honey bees included. It is rich in nectar, and its pollen contribution is good.
It flowers in July–August, when lime and black locust are long over, and lasts three to four weeks. This timing coincides with the rearing of winter bees, which makes it very valuable.
Because plantings are scattered, no separate honey is produced; its nectar goes into mixed late summer honey and the winter stores.
It grows easily from seed and comes into flower within a few years. It does well in sunny, warm, well-drained soils; young trees can be damaged in very cold winters. Because it sets plenty of seed, seedlings may appear around it, so take care when planting near natural areas.
