I never used Plantstep. I have an Appleworks database and could move things over to Excel. I have 250 daylilies. As far as identifying them, see what daylily people in your area have at test gardens. Do you have an AHS club in your area?
I have had some luck with club members identifying things for me. I don't hybridize, I just grow things I like and sometimes that is because of the name, and sometimes it is because of the color. My husband shares my addiction and helps me plant and he does most of the watering. There are 70,000 daylilies but if you consider where you got the plants, you can narrow that down. You have to take measuring tape and note the height of the scape, and size of the blossom. That cuts down possibles as well. I label everything now but had a problem with the lawn cutting service blowing away tags so we keep a computer record where we plant things and my husband did some garden diagrams of locations.
