Maureen K. Chilton Azalea Garden
May

The Mother’s Day crescendo of white, coral, pink, and purple azalea blossoms is one of the Garden’s most striking seasonal spectacles. Set amongst the dramatic rock outcrops, steep slopes and dappled shade of centuries-old native trees, this garden is beautiful throughout the seasons with plants in bloom nearly every day of the year. Alongside the azaleas and rhododendron, you’ll find a diverse assortment of flowering trees and shrubs, woodland perennials, bulbs, ferns and grasses. Collections in this garden include dogwood, mountain laurel, hydrangea, spice-bush, witch-hazel, epimedium, hosta, hellebore, snow-drop, and ferns.

Additional Information

Azaleas

Azaleas (Rhododendron spp.) are found in various places across NYBG, but they are the star of the show in the Maureen K. Chilton Azalea Garden, where the incredible diversity and beauty of these popular garden shrubs is on full display. The spectacle of the Mother’s Day slope covered in painterly swaths of pink, white, and fuchsia is all thanks to selections of Asian evergreen azaleas which peak around the second or third week of May. Don’t forget this garden has a lot of plant diversity and looks beautiful in all seasons!

The Collection

We’re not shy of azaleas here at NYBG! You’ll find 6,706 individual azalea and rhododendron plants, which represent 456 different species, hybrids, and cultivated varieties.

The Locations

Most of our azaleas and rhododendrons can be found in the Maureen K. Chilton Azalea Garden, but you’ll also discover them blooming in the Rock Garden and Native Plant Garden.

The Facts

  • Beginning in the late 1890s, a variety of species and cultivars were planted in the Fruticetum (part of the north section of the Garden that was lost in the ’30s when they built the Cross Bronx Parkway) and in decorative plantings at the Garden’s gates.
  • In 1910, a planting of 800 Rhododendron maximum, R. minus, and R. catawbiense from the Biltmore Estate in Asheville, North Carolina was installed on the slopes above Twin Lakes. This area was known as the Rhododendron Glade.
  • The Garden significantly expanded its collection of rhododendrons and azaleas in the 1940s. In 1940, 435 seedlings of unnamed hybrids of Rhododendron fortunei, all of which were raised by Charles O. Dexter of Sandwich, Massachusetts, were planted along the northern edge of the Thain Forest.
  • From 1943–1946, thousands of azaleas and rhododendrons representing hundreds of species and cultivars were planted in an “Azalea Garden” in the high shade of native trees along the Bronx River, in the southwestern portion of the grounds.
