Decorative Perennial Vine For A Trellis
Q: I am looking for a decorative perennial vine to adorn my vegetable garden
trellis. Blue passion flower has been recommended. What do you think?
A: I have personal experience with blue passionflower (CQ), Passiflora
caerulea, in my garden. I will never plant it again. It is highly invasive by
means of roots and seeds and is the very devil to control. A friend had a
horrible skin reaction from pulling the vines. This is not the same vine as
maypop, Passiflora incarnata, whose edible fruits also make excellent
ammunition for childhood “wars”. Depending on the size of your trellis,
consider instead one of the compact clematis varieties, like ‘Abilene’, ‘Akita’,
or one of the Boulevard series of clematis.
