Phacelia Tanacetifolia is a quick growing hardy annual green manure that germinates at low temperatures. It will grow up to 1m in height and is tolerant of cold temperatures and may over-winter if it's not too cold. It suits most soil types but is particularly good in dry ones.

Phacelia does not fix nitrogen but is a very rapidly growing annual nitrogen holder. It is particularly good at attracting bees, hoverflies, and wasps.

Phacelia has beautiful, scented purple/blue flowers, new seedlings are generally ignored by slugs and once grown will produce dense fern-like foliage. It smothers weeds and has an extensive root system that improves the soil structure. However, it does self-seed very easily so if it is used as green manure dig in before flowering or cut down and compost the foliage. It flowers from 6-8 weeks from sowing for a period of 6-8 weeks.
