Pinus strobus 'Pendula' is a loosely branched, strictly weeping form of eastern white pine that requires staking at first to obtain the desired height. Later, somewhat dominant lead shoots will develop, but will then continue weeping, eventually forming a large mound. Needles are generally abundant, long, and blue-gray to blue-green in color. Branches often grow outward in a sweeping form. This conifer will eventually become a large tree and makes a fantastic and elegant form for the garden that has the room for it.
After 10 years of growth, depending on staking and the tree's individual habit, a mature specimen may measure up to 15 feet (5 m) tall and wide, suggesting that lead shoots will extend at a rate of 12 to 18 inches (30 - 45 cm) per year.
This cultivar is one of the oldest and best-known selections in the nursery trade. Its first mention in botanical literature was in J. Nelson's 1866 work, Pinaceae: Being a Handbook of the Firs and Pines.
