Description Also called Spike Phacelia, Spiderflower and Fiddleneck, Blue Curls can be found in roadside ditches in Texas, New Mexico, Arizona and Mexico. They will grow in sand, loam, clay, or limestone soils; they aren't really all that particular. They do like a bit of extra moisture although they don't want to have their feet in standing water. Be sure to give them well drained soil.
