30 Plants to Grow Alongside Your Bell Peppers

Bell pepper (Capsicum annum) is one of the most coveted garden vegetables that pair well with other crops in the kitchen and garden. It is also a warm-season annual when grown in temperate regions. Bell peppers are considered “sweet” since they lack the pungent chemical (capsaicin) in hot peppers.

Bell peppers are more challenging than other crops and need a long growing season of up to 90 days. You can plant bell peppers directly in the ground, in raised garden beds, or a large pot. When cared for properly, they’ll produce more peppers all year long.
