|Rambling across a mat of delosperma |
Low-growing pipevine species with dark purple, narrowly arrow-shaped leaves. The vines can grow up to 3 ft long, but tend to grow to form a mat rather than twine upward. Native to the U.S. Southwest, it is host to the pipevine swallowtail caterpillars, who have developed immunity to the plant's toxins. Curiously shaped flowers are pollinated by small flies, which explains why they smell musty rather than sweet. We bought a pot of this plant which turned out to have many plantlets, so we put it in a few places. The only place it survived is our rock garden, where it seems happy but not overly vigorous. It has taken to sending its trailing stems across other low-growing inhabitants of the area, most notably an ice plant with which it contrasts nicely.
||well drained soil, heat and drought tolerant
Thus far, no sign of any caterpillars, and I must say I'm not surprised – if I were a butterfly I might look for a pipevine with more substantial leaves to feed my babies!
|I haven't noticed the flowers yet, but did find these seedpods in early September |
In our garden, this plant grows in the following areas: Houston rock garden, rock garden zone

|Jim Baughman||Jun 13, 2021||Hi, I'm looking for a place that sells Watson's pipevine plants or seeds. They are host to the pipevine swallowtail...I remember the plants from my youth in Arizona. Do you sell them or know who might?|
I haven't yet managed to collect seeds, and don't know of any mail-order source for plants or seeds (I got mine locally). Good luck finding some.
