California Pipevine

Aristolchia californica

California's host to the Pipevine Swallowtail butterfly.

The vines get carpeted in "flowers" before the leaves emerge if given sun & rich soil,

easy to grow. Can be propagated easily by cuttings (or by seed). It is typical in

woodlands or brush in many places in Northern California.

Only a few small populations in San Francisco. We're on the waiting list to get

some. I'm propagating tons of it from an unknown source in my garden, I wonder

how variable it is genetically?

Although it is true that it would require many pipevines to guarantee the long term

survival of a pipevine swallowtail population, especially an isolated one, it is

also true, I think, that one could get lucky and have pipevine swallowtails in

some if not many years with a considerably lesser planting of the pipevine. The

pipevine swallowtail is a strong flier, roams more than many species. I think

having a significant planting of its favorite nectar plants would also increase the

odds in your favor of having it around. Ideally there would be pipevines and

appropriate nectar sources all over the neighborhood(s) round about. They say

in the East the eastern pipevine swallowtail expanded its range 1000 miles to the

west, following the cultivated pipevines.



Since many caterpillars are parasitized by wasps (who lay their eggs on them)

and thus die (slowly being eaten alive from the inside by wasp larvae) before

turning into butterflies, the best way is probably to move the eggs, which are less

frequently attacked. An analogy is moving plants; seeds are the "cleanest" way,

the best way to leave behind pests and diseases. Second best method for moving

lepidoptera to a new site is to move the smallest caterpillars you can find, or the

pupal stage. However, perhaps pipevine swallowtails are attacked less often

than some species; I saw them at high concentrations at the San Francisco site

and in Louise's garden. They are quite conspicuous, black and orange, I suppose

poisonous from eating the pipevine!

Here's my profusely blooming Pipevine:

http://www.EDGEHILL.net/pipevine.gif Four years old, growing in super thick

rich pine/ivy duff. Supposedly you need a hundred yards of fenceline covered

with pipevine to support a sustainable population of swallowtails. I'm hoping I

could start with a few as I grow more plants, I've got just a hundred & fifty feet of

fenceline.
