A perennial plant lives and blooms for many years.

A herb is a plant whose stems die back to the ground in the winter.

palmate -- Consisting of leaflets or lobes radiating from the base of the leaf.

capsule -- a type of simple, dry fruit produced by many species of flowering plants. In most cases the capsule splits apart to release seeds.

schizocarp -- a dry fruit formed from more than one carpel (a female reproductive organ) but breaking apart into individual carpels when ripe.

Like the teeth on a saw, leaves and other surfaces can have toothed edges.

fruit -- any seed-bearing structure in flowering plants. It is formed from the ovary after flowering.

In an opposite leaf arrangement the leaves come in pairs with one leaf on each side of a stem.

basal leaves -- a leaf that grows lowest on the stem of a plant.

genus -- A subdivision of a botanical Family in which all members have a significant number of similar characteristics.

alternate -- leaves alternate along the main stem and are attached singly.

linear -- Long and very narrow like a blade of grass.
