Aristolochia macrophylla

Dutchman’s Pipe
Deciduous, Vines


Twining vines noted for curiously shaped flowers in rather sober colors; they resemble curved pipes with flared bowls or birds with bent necks. Vigorous growers; thin out unwanted growth in late dormant season or wait until after bloom. If plant is too thick and tangled for selective thinning, cut it to the ground before spring growth begins.

Aristolochia macrophylla

Native to the eastern United States. Large (6 to 14-in.-long), kidney-shaped, deep green leaves are carried in shingle-like pattern to form a dense cloak on a trellis; the vine will cover a 15- by 20-ft. area in a single season and was once a favorite for screening a porch. Blooms in late spring, early summer. Flowers are almost hidden by leaves; each is a yellowish green, 3 in., curved tube flaring into three brownish purple lobes about 1 in. wide. Thrives in full sun to heavy shade. Average to good soil and ample water produce the fastest growth and the largest leaves. Dutchman’s pipe will not stand strong winds. Short lived in warm winter areas. Easily grown from seed.
