Just returned to hobby beekeeping after a 15+ year hiatus. The Bee-L is very informative. I do have a question. Many (20) years ago I bought some plants etc from a place (Pelham (?) Gardens) that specializerd in items for bees. I received two small bare rooted "trees" called in the catalog, Bee Bee trees. One died and the other has flourished. It is about 20-22 feet high, and produces myriads of very small yellowish flowers in the spring. The bees truly go wild over them and they last for weeks. The leaves somewhat resembel black walnut leaves, that is a central stem with multiple leaves branching off, and the bark is brown/gray and fairly smooth. Does anyone know the scientific name, and more importantly where I can get another one? Thanks! Dave Tennessee
