Bloom Period: Late spring through first frost; red-orange, burgundy, and yellow bicolor blooms
Mature Height: 1–2 ft | Mature Spread: 1–1.5 ft
Planting
When: Direct sow in fall (once soil temps drop below 50°F, typically mid-to-late November in low desert) for natural stratification, or in early spring
Where: Full sun; tolerates poor, sandy, or gravelly soil as long as it drains well
How: Sow seed at a depth of about ⅛ inch and lightly rake in. Keep evenly moist until germination, which takes 15–45 days depending on soil temperature - warm soil (70–75°F) speeds things up considerably.
Can be planted during monsoon season; wait until after first or second rain. Water every other day until sprouted and thereafter until temperatures cool off.
Growing Tips
Unlike its perennial cousin G. aristata, firewheel is an annual (occasionally short-lived perennial) - it relies on reseeding to persist, so let some flower heads go to seed each season
Establishes a healthy taproot before winter frost when fall-sown, giving it a head start on spring growth
Extremely heat- and drought-tolerant once established; avoid overwatering, which invites root rot
Care
Deadhead spent blooms to keep the plant flowering continuously through the season
Naturally deer- and browse-resistant
Not susceptible to significant pests or disease
Safety
Toxicity: Generally considered non-toxic to dogs, cats, and horses
Pet Safe (Dogs): Yes - same genus and profile as other Gaillardia species; hairy foliage may cause mild skin irritation on contact but isn't a systemic risk if nibbled
