the pretty flower i want is mixed up with another purple flower. separating them will take a bit of work and some care. i will want to wait until the seed pods are ripened and collected. at that point there will be no flowers to identify one plant from the other. so they will need to be flagged and removed carefully. i might even want to keep the other piece until i am sure i have the right plant. go slow and very careful grasshopper. and if i am very very lucky i just might get the plant that i want. what could possibly go wrong ? ! ?
