Cosmos Sea Shells Red Seed brings a distinctive twist to the classic Cosmos look. The Sea Shells type is known for rolled, tubular petals that create a fluted flower form, giving sunny South African beds and cutting rows an unusual textural finish.

Why Grow Cosmos Sea Shells Red?
- Unique sea-shell petal form adds interest beyond standard Cosmos blooms.
- Red-toned flowers provide strong seasonal colour in sunny beds and borders.
- Excellent for cut flowers, pollinator gardens and cottage-style plantings.
- Easy, quick and rewarding from seed in warm conditions.
- Regular cutting helps keep plants flowering.
Garden Uses
Plant Cosmos Sea Shells Red where its unusual fluted petals can be seen up close: along paths, in cutting rows, in mixed annual borders or in pollinator-friendly displays. It works well with zinnias, sunflowers and other warm-season flowers that enjoy full sun.
Growing Notes
- Direct sow into prepared, well-drained soil and keep evenly moist until seedlings are established.
- Avoid overly rich feeding; Cosmos can become leafy and soft if pushed too hard.
- Deadhead or pick flowers regularly to encourage a longer flowering display.
- Protect young plants from frost and stake taller plants in exposed, windy positions.
