DESCRIPTION:
Scarlet pimpernel is a low-growing, branching annual. Cotyledons (seed leaves) are narrowly lance-shaped, football-shaped or egg-shaped and hairless. Leaves are opposite to one another along the stem and have purplish dots on the undersides and are somewhat rounded with triangular-shaped tips. They are arranged oppositely or in whorls of three along the square stem. Leaves may be attached to the stem by short stalks or they may be stalkless. Flowers are salmon-colored and open when it is sunny.
