What do these mean?



Aristolochia californicum, Dutchman’s Pipe, is named for its distinctive, ornate flower. It is often found in shady, moist areas but also under the dry shade of oaks. After winter dormancy it sends out branches along the ground and into neighboring vegetation to a height of up to 20 feet. The heart-shaped, apple-green leaves drape intermittently along the vines, growing at times to about four inches in length. Within its native range the emergence of the foliage corresponds to frequent sightings of the pipevine swallowtail, whose larvae feed exclusively on the vine. Happening upon a twenty foot vine covered in feeding caterpillars is quite a sight. In the garden, dutchman’s pipe seems to thrive with a little shade and regular water. It is at least semi-deciduous in winter.
