Bloom Period: Spring; indigo-blue
Mature Height: 6–12 in | Mature Spread: 6–15 in
Planting
When: Direct sow in fall in low-desert zones; as early as soil can be worked in higher elevations
Where: Full sun to partial shade; grows in rocky native soil or well-drained fertile soil alike
How: Loosen the soil surface with a rake or garden fork. Broadcast seed, mixing it with sand to help distribute evenly, then rake in lightly and press the soil to keep seed from washing away. Water immediately after sowing, then every 2–3 days until seeds germinate.
Growing Tips
One of the easiest wildflowers to grow - no special care required
Skip supplemental fertilizer; it encourages excess leaf growth instead of blooms
Reseeds freely, especially in rocky soil, and often shows up in charming, unplanned spots
Care
No pruning needed, though deadheading keeps plants tidy
Not susceptible to pests or disease
Safety
Toxicity: Not known to be toxic to pets or humans if ingested, though the glandular hairs and sap can cause contact skin irritation (a mild dermatitis) in people and animals Pet Safe (Dogs): Generally safe if nibbled, but the same irritating hairs can bother a curious dog's nose or paws on contact.
