A native species of North America, this is a more compact form than its Chinese and Japanese cousins.
This makes it ideally suited for large pots, which can be placed under pergolas or arches to transform them into a charming feature, well-suited to a cottage garden. If the garden is large enough, then plant them out against the wall of a house for an incredible late spring and summer display. Its dense clusters of lilac-blue flowers seem to drip from its twining stems and they emit a delicious fragrance, so make sure you plant it near a seating area or entrance if you can.
Garden care: To get lots of flowers, the twining stems need pruning twice a year - once in summer (about two months after the flowering has finished) and again in mid-winter.
