This is a pretty mixture of pinks whites and blues, on a tall plant which makes for an excellent cut flower.

Out of stock



This  plant mix has pretty fluffy  flowers in shades of blue, pink , mauve, burgundy and white . The flowers grow on a well branched bushy plant. The flowers are good as a cut flower because they have tall study stems and provide a light airy texture to bouquets. But they are also a valuable plant in the garden, where the mid green, heart shaped foliage with scalloped edges creates a useful foil for the flowers. The flowers are produced throughout the summer, and bees and butterflies are attracted to their light scent. Remove the old flowers to encourage further flowering, and tidy up the plant. The plant likes a position in full sun , with   moist well drained soil, though will tolerate partial shade, and doesn’t have many pest and disease problems.  It grows easily from seed, and can be used in containers as well as in the garden. It flowers in the first year from seed, about 3 months from germination.



Sowing advice

Sow indoors in trays or pots in spring. Surface sow onto moist well-drained seed raising mix which has been firmed. Ideal temp. 15-18°C. Do not exclude light as this aids germination. Germination takes 10-15 days. When seedlings are large enough to handle transplant to 8cm pots and grow on in cooler conditions. Acclimatise and plant out once danger of frost has passed with 50cm spacing.
