Overview

Frilly pinkish-blushed blooms frolic atop this whimsical cosmos. As the summer progresses, these dwarf charmers prolifically produce candy-striped and snow-capped semi-double flowers with abundant glee that rise above bushy bundles of feathery foliage.

A long seasonal, easy-to-grow annual, Cosmos bipinnatus ‘Cosimo Collarette’ continues to lift spirits well into autumn with staunch cut-flower potential.

Specifications

  • Position: Full sun
  • Soil: Moderately fertile, moist but well-drained soil, or peat-free general purpose compost
  • Rate of growth: Fast-growing
  • Flowering period: June to October
  • Hardiness: Borderline hardy (will need protection in winter in colder areas)

Care guide

Pot on and grow on in a well-lit and ventilated frost free environment (such as a greenhouse, coldframe or conservatory). Plant out after all risk of frost has passed.

Pinch out the growing tips to encourage bushier growth, and feed at regular intervals throughout summer with a high-potash fertiliser. Taller plants may need supporting with brushwood stems in exposed positions.

Planting requirements

  • In early spring, sow seed shallowly in seed trays and keep under glass, transplanting them into individual pots when large enough to handle. Harden off before planting outside after the frosts.
  • Alternatively, sow in-situ in mid- to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm (12in) between each.
