Phacelia tanacetifolia / Fiddleneck / Seeds

Fiddleneck is an upright hardy annual with clusters of lavender-blue flowers for a long period over the summer, from June to October.  Plants grow to a height of 40-80cm, sometimes taller.  They are very appealing to bees and other insects and are good cut flowers. 

Plants grow best in full sun and well drained soils.  They look their best in wilder spaces and prairie-style gardens and grow well in cut flower beds.  They can be used to improve the fertility of soil, where plants are dug into the soil before flowering.   

Caution: skin irritant 

Pack of 1 gram (approx 600) seeds.  Sow the seeds outdoors in spring or autumn directly into cultivated soil.   Sowing instructions and a colour photo are printed on the packet.
