This photo reminds me why my son (13 now) loves lobelia erinus.
I generally plant perennials.
But this beautiful flower has brought my son and I close, planting them together each year.
Something wonderful to do besides football, racing, and such!
It is so refreshing to read that you and your son garden together. He will remember the wonderful times you have shared and you have given him a love of plants which will last him a lifetime. Thanks for your comments.
