Nursery contributed plant descriptions

Who doesn’t love watching the ungainly antics of bumblebees or finding them asleep on your flowers? Soo cute! Well, this lovely annual native to Alameda County & Southern California, may be the #1 bumble bee magnet, seducing our fuzzy friends from near & far with its abundant stores of pollen & nectar. Exceptionally pretty, grape-candy scented, 1.5-2” intri cately marked, lavender-blushed-blue blooms are pre sented in many-flowered clusters atop upright, branch ing stems to 3’ tall and 16” across. EASY & fast, just provide decent soil with a bit of compost added for best bee-fest! Self-sows! *The tiny hairs on Phacelia can cause skin dermatitis for some people so be sure to wear long sleeves & gloves when gardening around them!
