The Story
Plant Bio
Capsicum annuum is an upright, bushy tender perennial from the warm Americas, grown as a frost-free warm-season annual with smooth green foliage. It bears small white solitary flowers that set hollow, fleshy-walled pods.
'California Wonder' is an open-pollinated heirloom from 1928 selected for blocky, thick-walled sweet bells about 4 inches long and 3 inches wide. Fruit sets green for crisp picking and ripens through yellow-green to rich red with zero heat, on sturdy upright plants reaching about 2 feet tall.

Planting
How to Grow
- Plant in full sun with 6 to 8 hours of direct sun in well-drained loamy or sandy-loam soil at pH 6.0 to 6.8.
- Start seed indoors in warmth above 64 degrees and set transplants out only after frost risk has passed and nights stay warm.
- Feed with balanced fertilizer at planting with ample phosphorus and calcium and avoid high-nitrogen formulas.
- Mulch and water consistently to keep soil evenly moist to prevent blossom-end rot.
- Stake if fruit load leans plants and pick green for crisp texture or leave to full red for sweetest flavor.
Pro Tip
Keep water even from flowering on; alternating wet and dry triggers blossom-end rot and thin walls, while excess nitrogen pushes leaves at the expense of fruit.
Keep It Thriving
Care Guide
Do
- Water deeply and consistently to keep soil evenly moist through flowering and fruit sizing.
- Mulch to hold moisture and buffer soil temperature.
- Feed with balanced fertilizer at planting, supplying phosphorus and calcium for wall development.
Don't
- Do not let plants wilt between waterings or fruit walls stay thin and ends rot.
- Do not push heavy nitrogen, which grows leaves instead of peppers.
- Do not eat leaves, stems, or flowers, which contain solanine-type alkaloids; eat only ripe flesh.
