Sweet pea's ??

I Am thinking of planting perennial scented sweet Peas for a change. i have been planting the usual annuals for a few years now with a great deal of success but was thinking for a change try Perennials ?. are perennials as strong scented as annuals ?
are they as easy to grow as annuals ?are the colours as strong as annuals?
what is the procedure after flowering ie pruning. thank you music. .

 

Virtually no scent.
Easy to grow. No need to keep cutting them to prolong the flowering season.
Colours are a pale comparison to the annual varieties. Pink, puce and white.
Cut back to ground in autumn like most herbaceous perennials. Very hardy (a friend's dog wees on her clump which grows up an old tree and it survives year after year).

 

They look great in hanging baskets!

 

Thanks Sussexgardener ,they do sound rather Lackluster, i think i will do what i have been doing for a number of years and stick with the annual sweet peas. i have built an extension of @ 2ft in height onto the top of my fence with plastic mesh to accommodate the height of growth i had last year, as the fence was six feet and they were drooping over to next doors garden . funny she asked me last week" when i was planting my sweetpeas" she said they had a beautiful perfume in her house in her vases ! music .

 

They are brilliant for scrambing through an old hedge or over a wall or fence - somewhere that doesn't require access, such as the annual varieties do.

 

Hi Music. As Sussexgardener says the colours are not as bright and the scent is not as good but they are very easy and practically self caring.
I grew them in my last garden which was very big and I had to have some low maintenance areas. There is a place for them in that kind of situation but if you want the real thing they don't stand up to annuals.
