Q.autumn joy sedum no color in blooms
I am a novice gardener. My sedum is at least 15 years old and never knew it should have color in its blooms. It blooms great but blooms are grey. It gets 6 to 8 hours of sun a day and spreads every year. Is there anything I can do to get color in the blooms? It seems very healthy, thank you.
Perhaps your plant was mislabeled from the nursery. This does happen.
Autumn Joy is a color that is easy to pick out in the garden, so it would seem you have a different Sedum Variety.
Hab Grey fits your description.
