Flowers

In Lancaster County, we have our own flower trial garden where ag scientists evaluate more than 900 varieties of flowers every year. They study how each plant handles Pennsylvania’s climate and pests. At the Southeast Agricultural Research and Extension Center near Spooky Nook Sports, staff monitor the plants for their growth and uniformity, plus the flowers and foliage.

Here are the top-performing varieties of a few popular plants over a period of several years. Information on dozens more plants, from achillea (yarrow) to zinnias can be found online.  

To see the plants in person, the flower trials are open June 1 to Aug. 31 from dawn to dusk.
