A distinct Caucasian shrub, 4-5 ft. high, with serrated leaflets and erect branching racemes of white flowers. S. pinnata, (Job's Tears; St. Anthony's Nuts), 6-12 ft. high, produces its white flowers in May, followed by roundish white nuts in a bladdery capsule. These two species are largely grown in pots and are forced into early flower under glass. Other species are Bolanderi, Bumalda, and trifolia. A fine hybrid, called Goulombieri, has been raised between colchica and pinnata. Staphyleas grow in ordinary good garden soil in sheltered spots and are raised from cuttings of the ripened shoots, layers, suckers, and seeds.
