Shouldn't be too hard. Swallowtail Garden Seeds has a terrific selection.

At least online, just like all the others that have pink poppies. Swallowtail Garden Seeds does not have Linum lewisii. To give them the benefit of the doubt they may be calling it ''common flax''. Their pink poppies are in a mixture, not sold separately.

Since pink poppies are fairly common and Linum lewisii is fairly common it is curious that it is difficult to find both.

I just discovered the ''sources'' forum. I will go over there.
