Despite all having 'lily' in their common name, none of those plants are true lilies :-) The lily of the nile (Agapanthus sp.) is/was a member of the onion family, Alliaceae (now assigned its own monogeneric family); the spider lily is a member of the amaryllis family, Amaryllidaceae; and the ditch lily is a daylily or Hemerocallis. There are separate forums for each of those but you may receive more responses by posting this is your local regional exchange forum. Just look for the two opposing arrows after the forum listings....these indicate those with exchanges.

I agree with Gardengal... None of them are lilies.
I can only add that many people would be happy to give you the "ditch" daylily (Hemerocallis Fulva) for free or for postage. This thing is very invasive (at least, in my zone). If you will not find them on your local forum, try Plant Exchange forum.

thank for all the good advice... i will look in those forums to see what i can find... :)
