Solanum crispum 'Glasnevin'

Plant details

The Chilean potato vine is just the thing to give a sunny wall an exotic look. It has wiry stems, which need tying up to wires or trellis for support, clad in small semi-evergreen leaves which remain on the plant in all but bad winters. The potato-like flowers, each with lilac petals around a pointed yellow centre, appear continuously from mid-summer to mid-autumn. The variety 'Glasnevin' is the one to choose, as it flowers more prolifically and is also slightly hardier than plain Solanum crispum. This is trouble-free once established. Plants enjoy moist but well-drained soil that is neutral to slightly alakaline in pH. To propagate, take cuttings from summer to early autumn. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).

Solanum Crispum planted last Autumn , label showed it to be a climber, it has turned out to be a bit of a thug , not a climber at all, but had to be tied in and has now pulled my fence down , the flower are really wonderful and prolific but obviously the plant is not suitable for the position against a fence !!!
I shall have to cut it right down and think again , would a small leaf Ivy be better ? Can anyone suggest one that will not become a thug and will be beneficial for my insect / bird wildlife ....

Thanks Wendy7, I have one against a fence and whilst I love it, I will now prune it to try to keep it in check. I have small and larger leaved ivy (given so don't know names)on same long fence and has spread over last4years but I'm hoping birds will nest so I just trim it like hedge.

I have mine against a wall growing through a flowering cherry which gives it extra colour late summer and provide a little screening in the winter when all the leaves on the trees have gone. I too originally thought it was suitable to grow as a climber on trellis attached to the wall but it is not. The main stem grows very thick and wrecks the trellis. I don't prune and it flowers reliably each year. Every plant has a place but not on trellis for this one!

Very much a thug I grew mine next to a chain-link fence but it's just spreading everywhere, so I am going to do some pruning to keep it in check.
