1 g. Lacy Phacelia tanacetifolia seeds, ~500
Phacelia tanacetifolia is an annual herb that is a magnificent magnet for bees and butterflies. It grows erect to a maximum height near 40 inches with none to a few branches. The leaves, 1–8 in, are mostly divided into smaller leaflets which are deeply and intricately cut into toothed lobes, giving them a lacy appearance. Will survive a frost.
If you want to bring bees and other beneficial insects to your garden, start with Lacy Phacelia. This annual wildflower grows well in hot, harsh desert conditions, but it grows easily in other environments too. The Lacy Phacelia flower spike is light blue-violet and has bees busy all day long, with foliage that is fern-like and lacy in appearance. Give it a sunny location in the garden and water from the roots occasionally. Sprinklers can make the stems flop over.
Phacelia Tanacetifolia cover crop use is becoming more and more popular and is used similarly to buckwheat as a winter cover cover.
