Phacelia grandiflora

Wildflowers Dicots Eudicots Asterids Boraginales Boraginaceae Hydrophyllaceae Phacelia

Giant flowered phacelia.

These cover hillsides in the year immediately after a fire, after that they become less and less common, but they can usually be found if you look hard enough. After the Jesusita fire they were all over Jesusita trail, but in 2013, 4 years later there were only about 10 on the entire trail. In 2013 they covered the burn area of the Cold Fire on Cold Spring trail.

The plant is covered with fine hairs, and if I walk through a thicket of them these hairs feel like tiny needles as they embed themselves into my flesh. A few hours later the affected skin develops a rash which feels rather like poison oak and lasts for several days. The results are not as virulent as poison oak, and it takes a fairly sustained scramble through the plants to achieve a rash; still it is best to enjoy the flowers without touching them.

Blue flowers a bit more than an inch in diameter.

Blooms Feb-July.
