Description

edit

Potentilla marinensis is a perennial herb growing in low, dense patches. The leaves are up to 10 centimeters long and are made up of toothed, hairy, gray-green leaflets each around a centimeter long. The foliage is glandular and strongly scented. The plant produces green to reddish-green stems up to 30 centimeters long which bear inflorescences of dense clustered flowers. Each flower has minute bractlets under reddish-green, fuzzy sepals. The petals are generally white and narrow with rounded ends. The center of the flower contains a ring of stamens around a patch of 20 to 30 pistils.
