Flared lavender-blue trumpet flowers with bright blue pollen, and loved by bees and butterflies, open on hairy stems bearing toothed, hairy leaves, very late in the season, from May into August. This astonishing tough perennial (yes! A bone-hardy perennial phacelia) is native to cold Douglas Fir and Redwood forests in Northern California and Oregon, and makes an amazing display in any open spot.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
