Anybody remember the name of the lady who did house plant demonstrations on Johnny Carson? She had a show on PBS, too. She was quite fastidious and persnickety and Carson would have fun screwing up her performance as she would criticize his inability to follow directions.
The Plant Lady was Thalassa Cruso.
Yes, Thalassa Cruso. I have saved many a houseplant by referring to her book, Making Things Grow.
