A dainty long-flowering annual from the Cape Floral Kingdom, with deep blue flowers from June through to August.  The plants grow 20-30cm in height, and the flowers cover the plant entirely when in bloom.  Plants do well in cottage gardens, pots and baskets.

Nemesia likes full sun or part shade and rich well drained soil.


Pack of approx 500 seeds.  Sow in spring for planting out after the last frost.  Sowing to flowering is normally 12-16 weeks, depending on conditions. Sowing instructions and a colour photo are printed on the packet.
