Common name:Weeping Colorado Spruce
Botanical name:Picea pungens 'Pendula'

Picea pungens 'Pendula' is broadly spreading selection of Colorado spruce with lax, strictly weeping lateral branching. If not staked, this conifer rambles along the ground. The branches just hang limply down creating a pole like appearance with the bottom branches creeping across the ground. It is a robust growing plant, with terminal buds extending 1 foot (30 cm) or more on a yearly basis. Ultimate height is determined by the height of the stake used to support the young plant. Needles are bright Blue that fade to dark green in their second year. Internal and shaded foliage is also more green than Blue in color.
