Cauliflower Winter Parotis F1 Seeds | Hardy Roscoff Type | Fosters Seeds

Cauliflower Winter Parotis F1 is a premium Roscoff-type winter cauliflower developed for dependable production during the coldest months of the growing season. Its strong, upright plants develop an impressive frame with abundant foliage that naturally protects the developing curds from frost, wind and adverse winter weather. This outstanding F1 hybrid has been bred to produce uniform, deep, dense white curds of excellent quality, making it a popular choice with professional growers as well as gardeners looking to harvest fresh cauliflowers when little else is available from the vegetable plot.

Taking approximately 250 to 270 days from transplanting to harvest, Parotis F1 rewards patience with superb crops from late March into early April. The curds are well covered by healthy wrapper leaves, helping them retain their bright white colour and excellent texture throughout the winter. One of the variety’s greatest strengths is its tolerance to stem frost together with good resistance to curd splitting and looseness, allowing reliable production even after challenging winter conditions or slightly delayed planting. The compact, dense heads are ideal for steaming, roasting, cauliflower cheese, soups and freezing.

Sowing & Propagation

Sow seeds from May to June in seed trays, modules or a prepared seedbed using a quality seed compost. Cover the seed with approximately 1 cm of compost and keep evenly moist during germination.

Once seedlings have developed several true leaves, harden them off before transplanting into fertile, moisture-retentive soil during June or July. Space plants 60 cm apart with 60 to 75 cm between rows, allowing sufficient room for the large plant frame to develop throughout the winter.

Growing On

Choose a sunny, sheltered position with fertile, well-drained soil enriched with well-rotted organic matter. Apply a balanced fertiliser before planting and maintain steady moisture during establishment. Once established, the plants become robust and continue growing steadily through autumn and winter.

Rotate brassica crops each year to minimise the risk of clubroot and other soil-borne diseases. Protect young plants from pigeons and cabbage white butterflies with insect-proof netting where necessary. The vigorous foliage provides excellent natural protection for the curds, while the variety’s good frost tolerance helps maintain crop quality during prolonged cold spells.

Harvesting

Harvest from late March through early April, depending on planting date and local growing conditions. Cut the curd while it remains firm, compact and brilliantly white, leaving several wrapper leaves attached to protect it during handling. The dense heads retain excellent texture and flavour, making them perfect for fresh cooking, freezing and a wide range of traditional dishes.
