Ginkgo biloba 'Spring Grove' (Spring Grove Dwarf Ginkgo)
It seems there are several clones going around under this name because there are at least two different dwarf Ginkgo trees at Spring Grove Cemetery in Ohio. We don't know which this is or if it is both; we started with more than one plant. But we do know they are dwarf and very attractive in conical growth habit.
Hydrangea quercifolia 'Queen of Hearts' (Queen of Hearts Oakleaf Hyrdrangea)
Another remarkable release from the U.S. National Arboretum's shrub breeding program in McMinnville, Tenn. in 2013 for which they should be rightly proud. Blooming a week later than other sections and holding its mature inflorescences even longer it really extends the season. The inflorescences are 9 inches long and age to pink while the plant grows to 6 ft. tall by 9 ft. wide.
