Beeplant often grows in very noticeable large colonies.

Capers are the pickled flower buds of a member of Capparaceae (Caper Family).

Linnaeus named this genus in 1753 and William Jackson Hooker named the species in the mid-1800s.  "Peritoma" is from the Greek for "cut around" and apparently refers to the circular splitting of the calyx base.  The word "Cleome" was used by Theophrastus several thousand years ago for Mustard-like plants. "Lutea" is Latin for "yellow".
