Paperflower

Name: Paperflower
Brand: Outdoor Dream Builders

Psilostrophe cooperi

A resilient desert native whose papery yellow blooms intensify with the monsoon rains and last for months.

Hardy in USDA zones 8-11; an evergreen low-desert native that shrugs off frost and extreme heat alike across low and mid elevations.

AMWUA Notes

Among the toughest, lowest-water flowering perennials, blooming for months on rainfall plus rare deep soaks.

Care Guide

💧Watering

Extremely drought tolerant — water every 2-3 weeks in summer and rarely in winter; it blooms hardest after monsoon moisture and needs sharp drainage.

✂️Pruning

Shear the mound back by a third once the papery flowers finish and turn tan to renew growth and prompt more bloom; a hard late-winter cut keeps it compact.

🌱Fertilizing

Never fertilize; rich soil causes weak, floppy, short-lived growth.

🛡️Pests

No notable pests; overwatering is the primary risk.

☀️Seasonal Notes

Evergreen mound that flowers spring through fall, peaking with the summer monsoon; reseeds modestly. The dried flowers persist as papery tan bracts.

Soil, Feeding & Propagation

🪨Soil

Lean, rocky, gravelly, fast-draining desert soils; thrives in decomposed granite and caliche; rots in rich or wet soil.

💧Drainage

Needs sharp, fast-draining soil.

🌱Nutrient Needs

None — thrives in lean desert soil without fertilizer.

🌰Propagation

Seed; direct-sow and it reseeds modestly into gravel. Short-lived; not divided.

📐Spacing

2 ft

🌳Roots & Placement

Minimal; a short-lived mound renewed by light reseeding. Overwatering is the chief risk.

Placement Tips

•Mass in rock gardens and gravel beds for a low, long-lasting cushion of yellow.
•Keep at the front or middle of a desert border where its 1-foot mound stays visible.
•Site in the hottest, driest, most reflected-heat spots — it thrives where others struggle.
•Let it reseed lightly into decomposed granite for a naturalized look.
