Vegetative characteristics

''Capsicum cardenasii,'' like most members of the ''Pubescens complex'', is a perennial plant that develops woody stems. The plant can grow up 2–3 feet high with a width of 1-1.5 feet. The leaves are narrow,

, pendant flowers. The corolla is white and purple colored. The plant produces small, fleshy, red fruit. It is likely the wild ancestor of rocoto peppers. The plant requires a cool, freeze free environment and long growing season similar to its native environment in the Andes.


Reproduction

After fertilization ''C. cardenasii'' develops small round red berries, sometimes referred to as chiltepins. The fruits contain a small number of seed. The fruit are pungent, near 30 000 SHU (

Uses

Its primary use is as a spice. Many wild ''Capsicums'' exhibit disease resistance of interest to plant breeders. ''C. cardenasii'' has been shown to be resistant to

(TMV), and there is a possibility that one day this resistance may be transferred to other capsicum species through breeding.
