Final image these plants are NOT unknown...
41249 is the uncolored version of the Campions again scattered this is a plant we never could grow before which is a shame IMO.
41251 This is another version of Campions we could never grow from seeds.
41255 is a small version of scattered Poppies that we can NOT get from any seeds at least so the client says (Identical to item ID#3263) Only uncolored.
41256 is the small Orfluer that we can NOT grow (incidentally there is also a single version of the Orfluer that they didn't include in the Barrow for some reason which is a shame)
41259 as I previously stated is the 2nd to the last growth phase of the Vanilla plant... again as I have already previously stated.
41247 is the large clump of flax which we could never grow either,
41183 the client lists as decorative vines (we have never had access to this plant before either and it's rarely seen in UO) there are 2 versions they turn.
41189 the client lists as a round bush???, However others are right it is in game as the plants that give the Lava Berries (This plant has been in the game for a long, long time however it's never been used until Eodon, which I think it's nice they found a use for it and I'm hoping they will eventually give us the Tomato plants which are also in the game files but they have never given us.)
Hope that helps some...
I could give you the original plants they come from ID numbers if you want.
Also if you would like to come take pics of mine to add to your charts you are welcome to just PM me.
