Named varieties of tree peaonies are quite pricey. I hope you are not casing the joint for what to pinch!! The most expensive ones are also usually the first to die!!

I'm dying to know what you need this info for? I have visions of someone you are not keen on offering to buy you a plant - and you saying "Oh, I'd like a....................". Ha Ha.

Maybe you just won the lottery or got a supermarket trolley dash kind of prize in the garden centre. Wow, imagine that!!

I suppose the most expensive are the ones that are hardest to propagate, to speak in general terms. Either that, or 'new' cultivars which are in short supply, or unusual/rare plants.

Go and have a browse in your loacl Garden Centre and check out the prices for the range they have there.

The most expensive plants are the ultra rare they is a seller in San Francisco who specialises in the ultra rare stuff some of the prices can be quite high also amaryllis flowering size bulbs are very costly.Have a look at the website below I have purchased a few items from this sellar.

Definitely Tree peonies imported from Japan where the main man only produces one or two of some varieties. (No point coming here we do not have any).
As for small plants which are rather expensive, Hepatica japonica forms. For a plant the size they are they must count as expensive (seen them at £50 plus) Again imported from Japan and in very short supply. And no we have none of them either.

There was a snowdrop (just one) on ebay that sold for about £130 earlier this year.

Hi Bulbaholic

Hi Steve, I must say that I really don't understand galanthophilia. I love them but not enough to get that excited - wee white things, yes? Now, crocus or iris, that is a different matter altogether, lol.
