In the garden

Lactuca sativa 'Doppler' is a clump-forming annual in the daisy family (Asteraceae) cultivated as a lettuce. Its upright, clumping habit makes it straightforward to place in mixed beds or dedicated edible areas, and it will set flowers in mid to high summer if allowed to bolt. Plant in a site with full sun on a loam soil of neutral pH; keep the soil moist but well drained to avoid root stress. The H2 rating (half-hardy) means it will achieve best results as a summer annual in most UK gardens and may need protection from hard frosts—conservatory or greenhouse positions extend the cropping season. It tolerates south-, east-, west- or north-facing spots and copes with both exposed and sheltered conditions. Placement options include cottage and informal borders, patio containers and bedding displays; it also suits greenhouse production where steady leaf supply is wanted. If plants are left to run to seed they reliably produce flowers between June and August, providing a brief period of summer blooms before seed set.
