Partridge Pea
Chamaecrista fasciculata — Pea Family
A native annual wildflower in the Pea Family that blooms in summer suited to dry, sunny conditions.
Planting Guide
When to plant
Direct sow after the last frost date. For an earlier start, sow indoors 6–8 weeks before the last frost.
Spacing
Space plants 1.5–2.0 feet apart. Closer spacing fills in faster and suppresses weeds; wider spacing gives each plant room to reach full size.
Root system
Roots reach at least 12 inches deep at maturity. Plant the crown at or just below soil level.
Growing Conditions
Sunlight
Full sun — 6 or more hours of direct sunlight per day. This species does not tolerate shade and will thin out or fail to bloom in shadier spots.
Soil & pH
Prefers a wide pH range from acidic to neutral (pH 6.0–7.5). Most average garden soils fall in this range; a quick soil test confirms your starting point.
Watering
Low water needs. Water weekly for the first growing season to establish roots. After establishment, natural rainfall is usually sufficient except during extreme drought. Once established (typically 1 season), it shows strong drought tolerance and can go extended periods without supplemental water.
Seasonal Care
- Start seeds indoors 6–8 weeks before last frost, or direct sow once soil has warmed.
- Transplant hardened-off seedlings after the last frost date for your zone.
- Deadhead spent flowers regularly to extend bloom period and prevent excessive self-seeding.
- Established plants rarely need supplemental water; deep, infrequent watering beats shallow, frequent watering.
- Allow a few seed heads to drop for natural reseeding next spring.
- After the first hard frost, remove spent plant material to reduce disease carryover.
- No active care required. Check if self-sown seedlings appear in early spring.
Wildlife & Garden Value
Ecological benefits
- A legume that fixes atmospheric nitrogen, improving soil fertility for neighboring plants.
Landscaping uses
- Dry slope or hell strip planting where irrigation is difficult or unavailable.
- Rock garden or gravel garden specimen; excellent for low-maintenance landscapes.
