Bloom Time: Spring to summer
Lewisia cotyledon is an evergreen perennial that grows from a thick taproot and caudex unit. It produces a basal rosette of many thick, fleshy oval- or spoon-shaped, up to 4 inches (10 cm) long leaves. The Latin "cotyledon," meaning "small cup," refers to the shape of the leaves. From spring to summer, the inflorescence arises on one or more up to 12 inches (30 cm) tall stems, 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 0.6 inches (1.5 cm) long. The petals may be pale pink with darker veining, whitish with pinkish-orange striping, or solid orange to yellow.
USDA hardiness zone 3a to 8b: from −40 °F (−40 °C) to 20 °F (−6.7 °C).
How to Grow and Care
Lewisia plants produce offsets, which are the easiest way to propagate this interesting little succulent. Simply divide them from the parent plant and pot them up to grow good taproot and fleshy feeder roots.
You can also learn how to grow Lewisia from seed. The tiny plants take a couple of seasons to form a rosette but establish easily when sown in a sandy potting mixture.
Once the plants are placed in a garden situation, provide them with moderate water, excellent drainage, and a minimum of nutrients. It couldn't be simpler to grow Lewisias. The primary thing to remember is to avoid excessively fertile soil and compacted or clay situations.
