Capsicum cardenasii

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, lanceolate and pubescent. Plants generally produce between 1 and 2 flowers at the internodes. The petioles grow erect and have campanulate, pendant flowers.[3] The corolla is white and purple colored.[2] The plant produces small, fleshy, red fruit. It is likely the wild ancestor of rocoto peppers.[4]

The plant requires a cool, freeze free environment and long growing season similar to its native environment in the Andes.[1]

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 (Scoville Heat Units), making them quite spicy.

Capsicum cardenasii is self-incompatible, and exhibits unilateral incompatibility with species outside the pubescens clade.[5]

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 tobacco mosaic virus (TMV), and there is a possibility that one day this resistance may be transferred to other capsicum species through breeding.[2]
