Berzelia is a genus consisting of 12 species of upright, wiry stemmed, evergreen shrubs with a dense covering of small, fine, needle-like leaves. The flowers which appear in spring and summer, are minute but are packed in spherical clusters, of which there are several per head of bloom. The flowers are white to cream and, because the stamens extend beyond the tiny petals, the flowerheads appear to be studded with protrusions.
