How to care for Cosmos bipinnatus Hummingbird Lilac:

Grow on under glass and plant out once all risk of frost has passed. Pinch out the growing tips to encourage bushier growth, and feed at regular intervals with a high-potash fertiliser throughout summer. Plants may need supporting brushwood stems in exposed positions.

Sowing instructions:

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 between each.
