Rating neutral as new in my garden. I did not plant it--it just showed up Spring 2015. It sure is pretty and delicate. I will keep it to see what it does...

I planted Phacelia Tanacetifolia by my raised bed. My intention was to attract as much bees as possible. It did not work. The plants are there, beautiful and tall; however, there are not bees, or butterflies. Anybody knows what's going on?

I agree with the other posts about how hover flies, bees, bumble bees LOVE this plant - especially the hover flies and native bees!!

The Fernleaf Fiddleneck, as called by Seeds of Change, loves full hot sun and goes completely flat in rain (or overhead watering), be warned. Installing soaker hoses has helped immensely, allowing it to bloom repeatedly and not be overwhelmed by the heat or the mauling affects of water. Once it is flat, it resents man handling, as it seems to be quite brittle and more apt to break than bend. The foliage is worth having, however, especially in a composition with a bolder leaf form. If you want to attract bees, have some of this around, it is busy 24/7. I got a second self seeded batch in late summer, in the direction of where my plants flopped. Also, it is a bit prickly, not something you want to grab. Last update is that the little guys that grew from the late summer seed batch died in th... read more

The flowers are very attractive to hover flies and other beneficial insects, however this plant is also excellent when used as a green manure.. To use in this manner the plants are turned into the soil before they reach the flowering stage, adding goodness and humus.

A U.S. native, P. tanacetifolium is grown as an annual in colder climates. Give good drainage and full sun. Self-seeds readily; deadhead to prevent unwanted seedlings.
