General
This annual is one of the best of all pollinator attractors of all. Bees simply love the ample, long-lasting, purple flowers. It is vaiously called Phacelia, Purple Tansy, Scorpion flower, or heliotrope.
Latin
Phacelia tanacetifolia
Family: Boraginaceae
Difficulty
Easy
Season & Zone
Exposure: Full sun
Zone: 3-10
Timing
No need to start Phacelia indoors. Direct sow every couple of weeks from last frost (end of March on the coast) to mid-June. This will produce a full summer of flowers. Seeds will germinate in 12-30 days.
Starting
Sow 5mm (¼") deep, and space or thin to 10-20cm (4-8") apart.
Growing
Ordinary, well-drained garden soil is what makes Phacelia thrive. It will die back during a long, hot stretch of weather, so it's ideal for the cooler seasons of spring and fall. Plants may self sow.
Note: Some people have a bad skin reaction to the plants, so wear gloves when pulling out finished plants.
