Description

It is an evergreen perennial growing from a thick taproot and caudex unit. It produces a basal rosette of many thick, fleshy oval- or spoon-shaped leaves up to 9 cm (4 in) long.

The specific epithet cotyledon ("small cup") refers to the shape of the leaves.[1]

Flowering from spring to summer,[2] the inflorescence arises on one or more stems 10–30 cm (4–12 in) tall, each stem bearing an array of up to 50 flowers.

Near the flowers are small, pointed bracts tipped with resin glands. The flower has 7 to 13 petals, each about 1.5 centimeters long. The petals may be pale pink with darker veining, whitish with pinkish orange striping, or solid orange to yellow.
