Phacelia tanacetifolia is a beautiful plant, ideal as a cut flower and beloved by bees and an excellent attractant of lots of beneficial insects like lacewings and ladybirds. The hungry nymphs of both these insects then munch away on less welcome aphids.

Phacelia tanacetifolia can later be dug in to build up the organic content of your soil or I love it as a cut flower.

Sowing, Seeds, Planting Sow direct March-June or August-October. Make sure the ground is weed free and work the soil to a fine tilth. Sow thinly and if growing as a cut flower thin to 10cm (4in) when the seedlings are about 2.5cm (1in) tall. Thin again 3-4 weeks later to 30cm (12in) to give them enough room to grow on without competition. Thinnings may be transplanted elsewhere in the garden or composted.
Care Tips Each crop should flower for up to six weeks, make repeated sowings every 8 weeks for a succession of flowers and a source of pollen and nectar for bees. Autumn sowings can be left to over winter as ground cover to supress weeds and also as a green manure. If growing as a green manure, dig in prior to flowering or cut down and compost the foliage. Will self-seed freely unless faded flowers are removed.
Flowering May-September
Vase Life Strip the bottom leaves and then sear stem ends in boiling water for 10 seconds. Leave in cool water, ideally overnight before arranging.
Harvesting Each crop should flower for up to six weeks. Autumn sowings can be left to overwinter as ground cover and a green manure.

I grow lots of plants to attract wildlife but last year I was surprised how much they preferred this plant to other plants. It was very easy to grow and it seems to have self-seeded so I hope never to be without this plant again.

If you have any spare soil or vegetable beds that you have nothing growing in then do chuck down a few handfuls of this. A mid summer sowing will see quick germination and the plants normally over winter well giving a bumper flowering show or sow in spring for flowering the same year. Bees and hoverflies love the soft navy blue wisteria scented flowers. Its often used as a green manure but how you can dig it in before allowing it to bloom is a crime I certainly could not.It will self seed a little.
