The latter are better known as chilies. While sweet peppers are at the market all year long, they are at their peak in the fall. Among the sweet varieties are banana peppers , pale yellow and about 5 inches long. The small ivory or very pale yellow wax peppers are very mild in flavor. We're probably most familiar with the bell peppers , which resemble their name.
Bells start out green but, if left on the plant, turn red.
Other bell varieties are yellow, orange, purple and brown. These vary in degrees of sweetness. Cubanelle peppers are long and tapered, and either red or yellow. Pimientos or pimentos are fleshy, bright red, heart shaped, and deep in flavor. They come to market in the late fall.
