At Lantern Court the pink-flowered weeping Higan cherry (Prunus subhirtella ‘Pendula’) is not far from Prunus ‘Snow Fountains’ by the salamander pool. There is a grove of the magenta-pink Sargent cherry, Prunus sargentii in the Conifer Collection and the Display Garden. One of the earliest and largest of our flowering cherries is Prunus subhirtella ‘Whitcomb’, on the southeast downslope of the Conifer Collection.
Serviceberries (Amelanchier arborea, A. laevis, A. x grandiflora) display their white flowers later in the month in all the gardens and also along the R. Henry Norweb Jr. Tree Alleé.
In the Layer Rhododendron Garden and the Eliot and Linda Paine Rhododendron Discovery Garden, heath, Erica is in full bloom and by mid to late April a number of small-leaved rhododendron including Rhododendron dauricum, R. mucronulatum and a number of showy cultivars including ‘Cornell Pink’ are to be seen. Forsythia 'Meadowlark', 'Northern Sun', 'Northern Gold', and 'Sunrise' will brighten up the Display Garden and Lantern Court, along with hellebores, Helleborus x hybridus that bloom throughout the month.
