Salvia patens / Gentian Sage / Seeds

A great first year flowering Salvia, with spikes of gentian blue flowers from July to September/October.  The lobed flowers grow on strong stalks 45 70cm tall, and have an intense blue colour that contrasts well with other plants in a border. These are also good in gravel and Mediterranean gardens.  They attract bees and butterflies into the garden.


Gentian Sage grows best in sun to part shade and a wide range of well-drained soils.  A position in well-drained soil helps these plants survive the winter, as they are on the edge of hardiness.   However, they flower in the first year from seed, so make good annuals.  Salvia takes good cuttings. 

 

Pack of 20 seeds.  Sow in spring and summer.  Germination is erratic, so sow more than you need. Sowing instructions and a colour photo are printed on the packet.

Hardiness Hardy to half hardy deciduous perennial (RHS Hardiness H3)
Flowers July to September/October
Height 45 - 70cm
Spread 30 - 50cm
Conditions  Sun to light shade and well drained soil
Sow Sow in spring and summer.  Sow on the surface of a tray of moist seed compost.  Gently press the seeds into the compost and do not exclude light, which is needed for germination.  Keep at a constant 20C and seedlings emerge in 2-4 weeks, and can be erratic so sow more than you need.   Pot on young seedlings and pinch out the growing tips to encourage bushier plants.  Plant out after the last frost.   Overwinter summer sowings in a cold frame or greenhouse in the 1st year.   
Grow Position plants in sun and well-drained soil to help them survive the winter.  Deadhead during flowering.   Remove spent flower stems as necessary and remove the plants in autumn if you are growing as annuals.  For perennials, take basal and softwood cuttings in late spring or lift the tubers in winter and replant in spring.  In warmer gardens mulch the plant in winter and it may survive and live for several years.
