Natural History Notes: This is a very tenacious vine that aggressively climbs nearly any wall or surface. It is so named for its 3-pronged claw-like climbing appendages. It is usually evergreen, though in the cold it may lose some of its leaves. It is often used for screens or to soften a hard wall appearance in landscaping. Also, cat’s claw gives off an impressive color display in early summer, with its many bright yellow trumpet shaped flowers. A major benefit for Arizona landscaping is that it is drought tolerant, even though it does have a more lush quality with regular irrigation. Its tenacity and hardiness make it very hard to eradicate, if unwanted.
