I'm in love with Proven Winners "Supertunias" and have planted them every year for the last few years in a window box.
They out perform/bloom any Petunia I have ever grown, however they are a Petunia hybrid.
Anyway this year I planted the dark red variety "Black Cherry" and it has not filled out like the other varieties I have grown, nor done as well. Anybody here grow Supertunia Black Cherry?
Here is Black Cherry, which is looking pretty ragged now
but this pic was taken before it started going downhill.
