Flora Pittsburghensis

Berberidaceae

Barberry Family

Mayapple (Podophyllum peltatum). Nothing else in the woods looks remotely like this charming plant. Each plant carries one or two umbrella-like leaves. If it has two leaves, it plans on blooming; one leaf means it will not bloom this year, and we have known whole patches where every plant stubbornly refused to bloom for years on end. The plant is poisonous, but when the fruit is ripe it is no longer poisonous enough to worry about and has a pleasant flavor, according to woodland lore.

Blue Cohosh (Caulophyllum thalictroides). A very strange-looking plant when it begins to bloom; the plant is almost eggplant-purple, and only half-formed, but already bearing brown flowers. Later the leaves will turn green and the flowers will turn yellowish, and it will look much more like a normal plant.

Berberis vulgaris

Japanese Barberry (Berberis thunbergii). A foreign invader; it makes a fine hedge, but it is beginning to show up where it is not wanted. It forms dense patches of thorny impenetrability in the woods. The red-leaved form is rarely found in the wild, but it does show up occasionally in the wild woods, where it is as little wanted as the green-leaved version. The little greenish-yellow flowers are charming, however.
