Description

Yes, this really is a true blue Penstemon, true from seed! Azure blue trumpet blooms in abundance, with green and grey tinged foliage. An added bonus too - as this charming perennial may be treated as a annual, flowering in its first year. Highly versatile for borders, rockeries, bedding or the patio container.

Sowing Instructions

Sow from February to early June on the surface of a good seed compost just covering the seed with a thin layer of compost or vermiculite. Early sowings can be treated like Half Hardy Annuals and will flower in their first year. Germination takes 14-30 days at 15-18C (60-65F). Don't exclude light, sealing in a polythene bag after sowing is helpful.

Aftercare

To treat as a perennial cut down the stems to ground level in the autumn and cover with a thick mulch of compost.
