There seems to be a difference of opinion between plant suppliers. Thompson and Morgan say Lord Andon's are scentless : Suttons say "deliciously fragrant" Question: Are Lord Anson perenniel sweet peas scented or not?
Perennial sweet peas are rarely scented. Is this variety an exception?
I've never yet been convinced that Suttons adverts or the blurb on their packets are written by gardeners
I've never known a perennial sweet pea with any scent and I've been around quite a long time
Dove, not that long surely I remember pterodactyls flying over Hyde Park! But I agree about the perennial sweet pea; awkward little bu....r that never really took off and certainly had negligable scent.
They can look pretty weaving in and out of an old picket fence around a cottage veg patch -in that sort of situation they look after themselves year after year - but unless I'd got that sort of garden I wouldn't grow it.
I've just done some googling, Lord Anson's Pea is Lathyrus nervosus rather than Lathyrus latifolius - the usual perennial sweet pea.
Apparently Lord Anson's Pea is a bit special and scented. However, it does seem to be a bit tricky to grow http://www.telegraph.co.uk/gardening/howtogrow/3303338/How-to-grow-the-everlasting-pea.html
I tried nervosus a few years ago and agree with what it says in Dove's link. I found it a weak grower - it then died on me just as it started to look as though it was doing ok.
