KevinI do have thoughts in my head as to what they might look like. It would be mind boggling to have a 'Oddity' x 'Killer'.
I will have to get brave and give the heuffelii a try next year. Bring on those yellow/golds Kevin.
Cheese Summer seems to hold that lovely yellow/gold color for a long period of time. Oh to try that one here in the Pacific Northwest.
