READER QUESTIONS
Q : I love wisteria but am having a heavy time with it here in Minnesota . It ’s not form much progress up my wooden arbor . -James A. Reider , White Bear Lake , Minn.
A : Your wisteria is root - Oliver Hardy , but all the top maturation it couch on each class is kill by austere winter temperature . No wonderment it ’s not getting anywhere on your arbor . The two most common wisterias areW. sinensisandW. floribunda ; the latter is a scrap hardier . Its flower clusters are tenacious and more fragrant , but if your plant has never blossom , the best way to severalise which one you have is the manner in which it twines : clockwise forW. floribunda , counterclockwise forW. sinensis . If you find you are growing the less hardy species , you might giveW. floribundaa whirl , or even better yet , the nativeW. macrostachya . You might also consider wrapping the new growing in burlap for a little extra protection . If swaddling it is out of the question , you may have to square up on another vine . by the way , I hope your arbor is made of potent , thick quality : wisteria ’s anacondalike stems have brought down many a finely wrought strait-laced porch and summerhouse .
Americans seem to have a impregnable distrust of vines ; we spring up them much less than other garden plants . It believably comes from a Freudian hang - up about lush , twining , probing shoots and tendril or , more likely , our veneration of the self - significant , halter spell tough we see taking over in nature - porcelain Charles Edward Berry , Hall ’s honeysuckle , and kudzu . I ’d like to see increased function of vines and more inventive room of growing them . Why not plant different vines at the base of your arbor and let them fight it out ? You ’ll have more interesting foliage shapes and texture and more flowers over a longer point of time . And , should some establish not as hardy or as vigorous as others , you wo n’t be leave with a spare arbor . Why not be Darwinian and let the tough Minnesota wintertime weed out the weaklings ?
seek trumpet creeper — the plain crimson species ( Campsis radicans ) , not the cite assortment that are less hardy — for its mysterious - green foliage and howling junglelike red flowers in recent summer . It ’s vigorous and can climb up a wooden mandrel unassisted . Native Dutchman ’s pipe ( Aristolochia macrophylla ) is a gamble in hardiness , but give it a try . It ’s rambunctious and mold a deep shade with its bombastic , tropical - looking leave-taking . A hardy , fast - originate native whose foliage turn scarlet in the dip is Virginia crawler ( Parthenocissus quinquefolia ) .
