Oddly, as many gardens as I tour each year, I haven't seen many of Oscie Whatley's cultivars. Kyle Billadeau did have a bed of his cultivars but for some reason, I didn't take individual pictures.
Several used to grow here, my favorite was RAM, which grew here for many years. It was a huge yellow with a white wire edge.
Like many, I have greatly admired Butter Cream.
Enjoying all the pictures, thanks!
