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.

How to use it

Uses in the garden

Harvest fruit at approximately 6 inches long while it remains tender and easy to pick. Harvest regularly. The packet contains Approximately 4 seeds. Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season. Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots. Before outdoor planting, gradually acclimatize young plants to wind, sunlight, and changing temperatures over several days. Follow the stated spacing so air can move between plants and each plant receives adequate light, water, and nutrients. Water at soil level when the surface begins to dry, then adjust frequency for weather, drainage, and container volume. A light mulch can reduce splashing and moisture swings after the soil has warmed and plants are established.
