I caught the addiction/illness after I bought my first house. The previous owners had put raised beds in, planted huge vegetable gardens and let them go to weeds. I wanted to fill them with something relatively easy to care for so I started looking at daylilies. One of the first nurseries I looked at was Maryott's. I couldn't believe the variety (or the prices for new intros) but I was mesmerized.
I wanted to try my hand at hybridizing because it seemed so easy in the sense of everything being so readily visible and manipulatable. That and I am a biologist by training so this was a way to do that at home. Lately I have been trying to get my younger cousins/nieces/nephews interested as an intro to science and gardening.
