CAPSICUM annuum 'Golden Calwonder'

Botanical Name

CAPSICUM annuum 'Golden Calwonder'( Grossum Group)

Plant Common Name

Bell Pepper, Golden Calwonder Pepper

General Description

Some believe 'Golden Calwonder' produces the most delicious yellow sweet bell peppers around. This classic 1948 introduction is just like the old-time favorite 'Calwonder' except its fruits are yellow rather than red when mature. Peppers are ready for harvest around 70 to 75 days after planting from seedlings. They are initially lime green and ripen to deep golden yellow. The blocky, four-lobed fruits offer a mild, super sweet flavor perfect for fresh eating or cooking.

Native to tropical America, these annuals had been grown and selected by Native Americans since pre-history times. In fact, their specific region of origin is still unknown due to distribution by man. Peppers became available to Europeans when the new and old worlds connected. Since then, many unique selections have been developed in Europe—particularly in warm Mediterranean countries like Spain, Italy and Greece where they grow well.

Peppers are bushy plants with rigid, brittle stems and thin, often broad, dark green leaves. Their flowers are inconspicuous, five-petaled and white. Peppers have firm, fleshy, hollow fruits that may be harvested green or allowed to mature to red, orange, yellow, purple-brown, or near ivory, depending on the selection. On the interior they are lined with spongy ribbing which supports many small, flattened, rounded seeds. Bell peppers are all members of the Grossum groups, due to their large size and distinctive shape.

Green fruits have a sharper taste and mature are sweeter, but the heat of a pepper is what most are interested in. Many peppers are spicy hot. Their heat is produced by a chemical called capsaicin measured in units called Scoville units against the Scoville scale ( The purer the capsaicin, the hotter the pepper and the higher the Scoville rating. Pepper seeds carry more heat than the flesh of the fruit. Still, bell peppers have the lowest heat of all and are almost never spicy.

Bell peppers are warm season vegetables that are easy to grow, if you can provide them with the correct conditions. Full sun, warmth, fertile, perfectly drained soil and regular feeding are required for good growth and fruit production. Peppers generally take 60 to 90 days to harvest. Some vascular wilts and fungal problems can befall them, but overall they are not needy. Proper spacing will keep diseases at bay and help with fruit production, so plant according to the grower’s guidelines.

Peppers can be ornamental as well as tasty, so enjoy them as bedding or container plants as well as vegetable garden standbys.
