The blossoms from a jalapeno plant (Capsicum annuum) are immaterial however the fruit is showy — shiny green 3-inch peppers that mature to colors of red and purple. Jalapenos are all members of this chili pepper collection of the pepper family and are sturdy only in U.S. Department of Agriculture plant hardiness zones 9 through 11, however they’re generally grown as annuals in other zones.
“Jalapeno” explains not only one but several chili peppers that land on the lower to mid-level of this Scoville Heat Unit Scale, the scale that chili pepper aficionados utilize to measure the spice in peppers. Jalapenos grow to 3 inches, but might grow up to a different 1/2 inch if left beyond maturity. The”Fresno Chili” is the very civilized jalapeno, scoring just 300 to 400 Scoville Heat Units — it’s also one of the smallest, measuring just two inches long at maturity. “TAM moderate” jalapenos measure 1,000 to 1,500 SHU — compared to this standard jalapeno at 3,500 to 4,500 SHU.
“Senorita” jalapenos — one of the hottest fruits in 5,000 SHU — turn purple, then red as they mature. Though jalapenos typically step between 1/2 and one inch in diameter, the 4,000- to 6,000-SHU”Senorita” is much more stout in 1 1/2 inches thick. A mature pepper that is generic, the jalapeno, registers 10,000 on the SHU, but measures. Jalapenos require 60 to 120 days to mature, depending on variety and weather requirements. Jalapeno”Mucho Nacho” grows to 4 inches long in 68 days.
