There were several things there I just loved. Beyond the experimental garden where they had different plantings and garden ornament which I always love to tour, there was a maze garden and children's garden of ABCs.
I loved this garden because it was a mix of common names and scientific names and they did not even stretch too far to find something for each letter.
For E they used Echinacea, it was too soon to tell it if was the purple variety or not, but that was my guess. For F they chose Floss Flower Ageratum houstonianum. I guess I never knew this name for this plant wish is a "Miller," like Dusty Miller, but then I saw it at the Rotary International Garden in Janesville, identified with this same name, so now I think this may be a Midwestern name for it and I still harken back to my Ohio roots when iidentifying plants by common names.
for Y they used the herb Yarrow and Z was for Zinna, one of my favorite flowers.....
