Plant description

Mounds of finely cut, filigree foliage clothe sturdy, upright stems that are topped with big (up to 12cm or 5in across) flower clusters. Initially flattened and lime green, these flowerheads gradually become dome-shaped, and open to greenish-white flowers. Their colouring acts as a wonderful foil for intense shades of plum and purple and the flowers last well after being cut and added to the vase.

Care guide

Visnaga may need staking, particularly in more exposed positions. This can be done in the early stages of growth of this hardy annual by creating a supportive framework, ideally with natural materials for the plant to grow through, which is preferable to reactive staking. Avoid cutting back some of the flowers before they have had a chance to set seed if you want to sow them for the following year.

Planting requirements

  • Sow shallowly in autumn and protect over winter in a frost-free location such as a cold frame or cool greenhouse. Prick out in early spring to larger pots and transplant in April to a sunny spot at 30-40cm (12-16in) spacings. Early sowings under glass can be made from March into a seed tray and kept moist, propagating with gentle heat (61°F or 16°C).
  • Pot on when large enough to handle. Can also direct sow in late spring into raked soil, 1.5mm deep drills, 30cm (12in) spacing, rows 30cm (12in) apart. Germination typically takes 21-30 days.
