The Q&A Archives: Change Of Color In Lupinus

Question: WE have planned lupinus from seed we harvested from a plant we have had and the color was pink. This year some pink ones have come up and then there are alot of purple ones, we are not sure were the purple color came from. Sometimes I know that a flower will change to a certain color when it gets old.

Answer: It is common for saved seed to produce a plant that is not the same as the parent, especially if the parent was a hybrid. In many cases the color, size, or habit of the new plant will resemble the species more than the parent plant. It sounds like this is what has happened here with the color. If you are careful to only allow the pink ones to seed down, and always pull the purple ones out right away, you might be able to develop a strain of reliably pink lupines over a long period of time, but there is no guarantee.
