Cuphea Growing Guide
Crop Rotation Group
Fertile, well-drained soil or roomy containers.
Can tolerate light frosts in warmer areas, where cuphea can be grown as a short-lived perennial.
Mix a light application of a balanced organic fertiliser into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.
Combine with other annuals, such as salvias.
Single Plants: 20cm (7") each way (minimum)
Rows: 20cm (7") with 30cm (11") row gap (minimum)
Sow and Plant
Sow cuphea seeds in moist seed starting mix and keep them warm until the seeds germinate. Most gardeners buy cuphea plants, which often are grown from rooted cuttings. Allow 30cm (12 inches) between taller varieties.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
This is a great summer flower for a sheltered spot or growing in a greenhouse.
Snip off older branches in midsummer to keep plants looking neat, and to prolong flowering.
Cuphea are rarely troubled by pests or diseases.
