Clarkia (Clarkia amoena, also known as Godetia) is a cool‑season annual beloved for its satiny, cup‑shaped blooms, soft pastel colors, and graceful upright habit. Flowers appear in shades of rose, coral, lavender, salmon, magenta, and white—often with watercolor blends and silky sheen. Clarkia is a classic cottage‑garden flower and a favorite for early‑summer bouquets.
What is Clarkia?
Clarkia is a cool‑season annual native to the western United States. It thrives in mild spring weather, producing abundant clusters of silky blossoms. It is frequently recommended in gardening guides because it grows well in lean soil, resists drought once established, and provides early color before heat‑loving annuals take over.
Why gardeners choose it:
• Satiny, cup‑shaped blooms with watercolor tones
• Excellent for borders, cottage gardens, and wildflower mixes
• Cool‑season performance with early flowering
• Upright stems suitable for cutting
• Thrives in lean soil and low‑water conditions
Growth Habit: Upright cool‑season annual
Bloom Colors: Rose, coral, lavender, salmon, magenta, white
Height: 18–30 inches
Sun Requirement: Full Sun to Light Shade

Planting Instructions:
• Direct‑sow outdoors in early spring or fall; Clarkia prefers cool germination.
• Press seeds lightly into the soil—light improves sprouting.
• Keep soil evenly moist until seedlings establish (10–20 days).
• Space plants 8–12 inches apart for upright, branching growth.
• Avoid rich soil or heavy fertilization; Clarkia blooms best in lean conditions.
• Deadhead spent blooms to extend flowering into early summer.
