There are few sights more stirring than a wisteria in bloom, and 'Amethyst Falls' offers all the romance without the unruly habits of the Asian cousins. This refined selection of the native American wisteria, Wisteria frutescens, pours out cascades of fragrant, lavender-violet blossoms in late spring, with smaller flushes through summer, a soft echo of springtime returning again and again.
For the first sixty-five years in the books, this vine was filed as a kind of soybean. Linnaeus named the plant Glycine frutescens in 1753, frutescens meaning turning shrubby, and there the classification sat until 1818, when Thomas Nuttall looked again, decided a woody climber of the southern riverbanks deserved a genus apart, and named the vine for his friend Caspar Wistar, the Philadelphia anatomist. Somewhere between the man and the plant a vowel slipped, Wistar becoming Wisteria, and the misspelling has outlived everyone involved.
Some years ago the late Lynn Lowery, a pioneer of Texas native plants, found a fine selection of native wisteria near the dam of an East Texas reservoir. The dam was known as Dam-B, and Lynn gave that name to the plant, though some contend the true name was Damn Bee. Woodlanders thanks Dr. David Creech of Stephen F. Austin State University in Nacogdoches, Texas, for the start of this and several other fine plants.
A rare white form of the well-behaved native. Wisteria frutescens var. nivea is a twining, woody, deciduous vine with compound leaves and short clusters of pure white flowers that open with the foliage, far less rampant than the common Asian wisterias and, in white, a genuine rarity. This form was virtually unknown to American gardeners until Woodlanders brought the plant into the trade.
The white form of the latest-blooming native. Wisteria macrostachya 'Clara Mack' is a twining, deciduous Kentucky wisteria with compound leaves and long, hanging clusters of pure white flowers, a splendid white version of a species normally blue. The racemes run longer and open later than those of the other native, Wisteria frutescens, extending the native wisteria season.
