Dudleya viscida

Dudleya viscida is a rare succulent plant known by the common name sticky liveforever.

Distribution

This dudleya is endemic to southern California, where it is known from only about 20 occurrences in San Diego, Orange, and Riverside Counties. It is mainly found on coastal bluffs and inland chaparral rocky slopes.

Description

The Dudleya viscida plant has a basal clump of erect fleshy, pointed leaves which are nearly cylindrical or most often elliptical in cross section. They are pale green to yellow-green or red in color and covered in a sticky, oily exudate which has a faintly resinous scent.

It grows erect stems with many-branched inflorescences, with each branch bearing up to 10 flowers. Each flower is pink to nearly white with red veining or streaks and protruding stamens between the pointed petals.
