In the garden

Cosmos bipinnatus 'Lemonade' belongs to the genus Cosmos in the daisy family and derives from a species native to the Americas. The cultivar provides a sustained display between July and October, making it useful for late-summer and autumn colour. Place the plants in a sunny, south-facing position with some shelter from strong winds; full sun and a sheltered aspect support longer flowering. Rooting into neutral, well‑drained loam or sandy soils is ideal—avoid heavy, waterlogged ground. The label H4 indicates average garden hardiness in the UK, so choose a protected spot in colder sites or grow in containers that can be moved when severe weather threatens. Where space allows, use Cosmos bipinnatus 'Lemonade' in mixed borders, cottage-style beds and containers, or sow in a dedicated cutting patch for vase work. Its upright habit suits it to background or mid-border positions where stems are easy to harvest. Expect a continuous run of blooms from July to October, which also makes it practical for regular cutting to bring colour indoors.
