Also known as Fiddleneck or Blue Tansy, Phacelia is an annual plant with ferny leaves and soft blue or lavender flowers.

It provides a very good source of nectar and pollen for pollinating insects including many species of bees and hoverflies.

Very easy to grow and generally pest and disease free, this plant prefers a sunny spot but can tolerate most soil types as long as it is well-drained.

  Phacelia provides food for the following creatures: 

  • Hoverflies
  • Short-tongued bees
  • πŸ¦‡
