That is just cruel. All those desirable plants.
No, not into variegated plants as such.

Is this research for your site?

I'm always on the hunt for more information. Buddlejas have really suffered from cultivars being renamed so one plant winds up with several names, plants get mis-named and cultivars become extinct.
Flight's Fancy, Trewithen, Elstead Hybrid and Lady de Ramsey are examples of lost B. weyeriana cultivars that may just have been renamed plants of the common ones (Sungold, Golden Glow etc.).
I am trying to rationalise these names on my site.
