Buy Phacelia tanacetifolia fiddleneck: Fast growing, and wildlife friendly

  • Position: full sun
  • Soil: any, fertile, well-drained soil
  • Rate of growth: average to fast-growing
  • Flowering period: June to September
  • Hardiness: hardy annual

    Lavender-blue, bell-shaped flowers, which are laden with nectar, form in densely-packed clusters on sturdy stems and attract bees and other beneficial insects in their droves. Perfect for wildflower meadows, or naturalised planting schemes, the flowers will last well after being cut. The fast growing foliage will help suppress weeds and makes an attractive groundcover. Scorpion weed can also be treated as a green manure crop, which will help enrich the soil. They self-seed freely.

  • Garden care: From early spring, sow into small pots filled with good seed compost and initially protect with a cold frame or unheated greenhouse. Pinch out the growing tips to encourage bushier growth and harden off before planting out. Alternatively sow direct in autumn into a sunny, well-prepared seed bed. Easy to grow, if you do not want the plants to set seed, remove the spent flowers as they fade.

  • Sow: March-May or September-October

  • Flowering: June-September

  • Approximate quantity: 25 seeds.

  • Humans: Skin allergen

Would buy seeds again


Seeds sown for gteen manure.




Happy hapless gardener


I ordered the seeds late in the season as I struggled to find the name of the plant or a seller. I had the original plants in a mixed selection from Unwins and spent a long time looking for their name online until I looked at Crocus and there they were! Crocus had the seeds and when they were delievered they were sown into pots. They grew beautifully and this year I will be planting straight into borders. A real pleasure to have come across Crocus and I will be using you again. I would heartily recommend you. Thanks!




Bee's love these


So easy to grow. I don't use the phacelia as a green manure, I just grow them for the bees. I have an area set aside for wildlife but the grass (couch) just takes over. The phacelia plants compete easily and unfortunately although they don't out compete the grass, it's easy to throw a few more seeds in and they still thrive, so there's always plants in flower.
