Q: I’m interested in night-blooming flowers and found Dutchman’s pipe online. Is that something I could grow successfully?

A: Dutchman’s pipe, Aristolochia macrophylla, will grow very well as a perennial deciduous vine. The flowers are insignificant. However, those of its annual cousin, calico vine, Aristolochia elegans, also called Dutchman’s pipe, are a dramatic checkered purple. Both are quite vigorous, so give either one an arbor at least eight feet tall and wide.
