Cat's Claw Vine
Macfadyena unguis-cati
In the United States:
Invasive
· also called catclawvine, yellow trumpet vine
Listed as invasive. Check local regulations — several jurisdictions restrict planting.
This vigorous climbing vine produces large, trumpet-shaped yellow flowers in early spring, drawing honeybees primarily for nectar during its brief but intense bloom period. It offers moderate pollen rewards and can contribute to early-season foraging in subtropical climates. The plant climbs aggressively using claw-like tendrils, requiring regular pruning to control growth and prevent it from overwhelming nearby vegetation.
