Yuca Vine
Merremia aurea
A Baja California vine with bright yellow summer flowers that dies back in winter and returns each year.
Root-hardy in USDA zones 9-11; the top freezes off in the mid-20s°F but the caudex resprouts each spring, and it thrives in intense low-desert heat with little water.
AMWUA Notes
A low-water Baja native vine that regrows from a water-storing root after frost, offering bright summer color with minimal irrigation.
Care Guide
Water every 10-14 days in summer once established; the large caudex-forming root stores water and gives it strong drought tolerance, so avoid overwatering.
Cut back the dead top after frost or in late winter; it regrows from its swollen root each spring, so hard seasonal cutback is routine.
Little to no fertilizer is needed; it grows readily in lean desert soils.
Essentially pest-free.
Bright morning-glory-like yellow flowers appear summer into fall; the top dies back with frost and resprouts from the caudex in spring.
Soil, Feeding & Propagation
Grows in lean, well-drained rocky or sandy desert soils; the caudex-forming root stores water for strong drought tolerance.
Needs well-drained soil.
None — thrives in lean desert soil without fertilizer.
Seed, or division of the swollen caudex.
6-8 ft apart on a trellis (10 ft mature spread)
Water-storing caudex resprouts after frost; non-invasive and well behaved.
Placement Tips
- •Give it a trellis or fence to climb about 10 ft for a warm-season screen or accent.
- •A refined lower-water alternative to Queen's Wreath where a smaller seasonal vine is wanted.
- •Site where its winter dieback and spring return fit the design, not as year-round cover.
- •Plant in full sun; the swollen root makes it very forgiving of drought.
