Boxwood produce small star shaped yellowish green pistillate (female) and staminate (male) flowers on the same plants. The flowers are not showy, but are quite fragrant. The star points are actually sepals - boxwood flowers have no petals. The flowers are in clusters consisting of a single female flower in the center, surrounded by several male flowers, recognized by their conspicuous yellow anthers.
Boxwood do well in partial shade. Dont expose them to full or mid day sun. If you want to prune them late spring is ideal.Boxwoods have shallow roots, so they should be mulched well and watered when the soil gets dry, especially if positioned in full sun. Boxwood cannot be subjected to wiring and so pruning branches is ideal. But in Asian countries a dreadful soil borne disease is found to distroy (dry out) the roots. So always be careful about soil. Do mulching.
