Photo and write-up by Bryant today:
Today’s image is of Lewisia cotyledon, and it was taken in the E.H. Lohbrunner Alpine Garden here in UBC Botanical Garden. Lewisia cotyledon is a member of the Montiaceae native to northwestern California and southwestern Oregon. There are three scientifically-recognized varieties and many cultivars that have been selected or hybridized.
Lewisia cotyledon is a perennial that grows from a thick taproot and caudex. The fleshy leaves can grow to 9 centimeters long and form a basal rosette from which the stems emerge. The inflorescence occurs atop the stem (usually 10-30 cm tall) and, depending on the variety, can produce up to 50 flowers.
Many species of Lewisia are adapted to growing in extreme alpine conditions, and thus are tolerant of both cold temperatures and periods of drought. However, I would have never guessed they would be capable of this!
