Costata Romanesco Zucchini, organic seeds
Cucurbita pepo
Costata Romanesco Zucchini, organic seeds (Cucurbita pepo) This open-pollinated Italian heirloom zucchini is known for its gently nutty flavour and light green fruit with pronounced relief. Harvested at approximately 6 inches, the fruit remains tender and easy to pick. The Gaia packet contains approximately 4 seeds certified organic by Ecocert Canada. The current list identifies the cultivar as annual, organic, and heirloom. Kew accepts Cucurbita pepo, an annual in the Cucurbitaceae family originating as a Mexican cultigen and introduced in Québec. Keep the cultivar name with the planting to distinguish this Italian zucchini from other vegetables called Romanesco.
Gaia publishes no lot-specific sowing protocol or numbered maturity period. For summer squash, direct sow after the last frost when soil reaches at least 21°C, approximately 1/2 inch deep. Indoor starting is possible 3 to 4 weeks before planting in individual pots that limit root disturbance. Grow in full sun and fertile, warm, well-drained soil. Space bush plants 2 to 3 feet apart. Keep soil evenly moist and remove floating row covers when flowering begins so pollinating insects can reach the separate male and female flowers. Avoid planting into cold soil because emergence and early establishment will be poor.
Gaia lists plants at 24 to 36 inches high and 36 to 48 inches wide. Harvest fruit regularly at approximately 6 inches long while the skin remains tender and the flesh firm. Fruit left too long becomes larger and can slow production. Use promptly or refrigerate for approximately 4 days. Its texture and nutty flavour suit grilling, sautéing, gratins, raw ribbons, and roasted dishes. Freshly opened male flowers are also edible. Gaia publishes no numbered days to maturity for this lot, so use fruit length, tenderness, and appearance instead of an invented calendar date. Discard any fruit with unusually strong bitterness.
