Yellow Orchid Vine
Callaeum macropterum
An unusual vine with yellow orchid-like flowers and decorative paper-like seed pods native to Baja California and Sonora.
A Sonoran native hardy in USDA zones 9-11; it is drought- and heat-adapted and takes light low-desert frost with only minor dieback, sprouting again in spring.
AMWUA Notes
A low-water Sonoran native vine well suited to desert-modern designs, offering distinctive flowers and seed pods with minimal upkeep.
Care Guide
Water every 10-14 days in summer once established; this desert-adapted vine is quite drought tolerant but blooms more reliably with occasional deep soaks.
Prune in late winter to shape and thin tangled stems and to guide new growth onto its support; it is a well-mannered climber that rarely overwhelms structures.
Needs little fertilizer; a light spring feeding is sufficient in poor soils.
Essentially pest-free in the desert.
Bright yellow orchid-like flowers appear in late spring and early summer, followed by decorative papery winged seed pods; it may thin or partially die back in hard frost.
Soil, Feeding & Propagation
Grows in well-drained rocky, sandy, or decomposed-granite desert soils; drought- and heat-adapted and tolerant of poor alkaline ground.
Needs well-drained soil.
Low feeder.
Seed from the winged pods, or semi-hardwood cuttings.
6-10 ft apart on a trellis (15 ft mature spread)
Well-mannered, non-invasive roots that rarely overwhelm structures.
