Where can I buy cheap perennials?

[Pannacotta]

I need an on-line supplier ideally and need to find lower prices than £4-6 per plant as I have a large flower bed to plant up.
Any suggestions please?
TIA

The cheapest I have found is Parker's wholesale here but you need to buy in multiples i.e Agastache "Black Adder" is £7 per five. Quality is very good usually.

Can't help with online but to bulk it out a bit, it might be worth putting a request on Freecycle as people might have plans to split clumps and may be able to offer some for free.

eBay

grow from seed and/or take cuttings from friends. Fill it with annuals this year - just scatter seed around (nigella, california poppies, whatever)

also many garden centres do £1 perennials early in the year

off to look at porridge's website - you need at least 3 of everything anyway so multiples not a bad idea

Ooh lovely Parkers website - getting credit card out now

That Parkers website is great. Thanks

Thanks all, Parkers are very good prices.
They dont have everything I need but is a good start and yes will check out local nursery for bargains and ebay (cant face Freecycle or taking cuttings, am too impatient!).

Join your local gardening club - many have plant and seedling swaps at this time of year.

Can second (third) J Parkers - I made a £70 order from them last month, all came in great condition. I've just made another order for me and my friends.

Probably shouldn't post this, but if you put the code GWS77 at the bottom of your basket page, you get 20% off everything until 1st May
