Aristolochia littoralis is much hardier than it looks. The Calico Flower has survived in the ground in
our garden at temperatures in the low teens. The top completely dies back and then sprouts back in the Spring,
but for a flower like this it is worth the trouble and wait. In our area Calico Flower can be expected to
produce 5-10 feet of new growth each year. The roots are a little tuberous. Aristolochia littoralis is
fertile from seed. The common name for the family is Birthwort. I am sure this has more to do with the
medicinal uses than its own fertility which is impressive. Aristolochia littoralis grows 2" flowers that
are just plain unusual. That makes it entertaining in any garden.
