Phacelia purshii
Miami mist
No garden should be without this uncommon annual with its delicate charm. No more than two feet tall it produces pale blue flowers with deeply fringed petals that produce a blue haze. Bees adore all the Phacelias and this one is no exception. It blooms in mid-May, starting bloom as Phacelia bipinnatifida is ending bloom, doing well in open fields and wood edges.
This plant wants to germinate in early winter so scratch in place in the fall. It will bloom for about three weeks, set seed and the whole plant will die quickly. Gather the seed and scratch it in where you want next year's display or let it drop; pull the plant and throw it on the compost heap or let it fade away under the new growth of other plants.
