*Summer requests for Morus germplasm should only be made if propagtion will occur under mist.

The Moraceae family has about 1,000 species which differ greatly from one another. Their commonality is that their stems and leaves are full of milky sap. There are three kinds of mulberry: American red mulberry, and the white and black mulberry. Mulberries look very similar to blackberries, the difference being that instead of the fruitlets being juicy, they are dry and surrounded by the fleshy parts of the swollen flower. The most important use of the mulberry is for the production of silk. Silkworms are fed the leaves of the mulberry. White mulberry originated in Western Asia, red mulberry in North and South America, and black mulberry is from Persia and Southern Russia.
