Strawberries are low growing herbaceous plants with a fibrous root system and a crown from which arise basal leaves. The leaves are compound, typically with three leaflets, sawtooth-edged, and usually hairy. The flowers, generally white, rarely reddish, are borne in small clusters on slender stalks arising, like the surface- creeping stems, from the axils of the leaves. As a plant ages, the root system becomes woody, and the "Mother" crown sends out runners that touch ground and root, thus enlarging the strawberry fruit is not a true berry. The flesh consists of the greatly enlarged flower receptacle and is embedded with the many true fruits, or achenes, which are popularly called seeds.
