Picea pungens 'Glauca Pendula' / Weeping Blue Spruce

Picea pungens 'Glauca Pendula' is a vigorous, irregular weeping or creeping selection of Colorado spruce with bright silvery-Blue colored, sickle shaped needles, especially in early spring and summer. A specimen will grow only as tall is it's final staked height. From that point, the terminals will "knuckle over," sprawling in all directions. One of the keys to identifying this plant is the tendency for terminal branches to turn obliquely upward.

Since ultimate height is determined by culture, note that this strongly growing conifer will extend from the terminal buds at a rate exceeding 12 inches (30 cm) per year creating a massive specimen in the landscape in pretty short order.

This cultivar originated as a seedling selected in the late 1800s by Koster & Co. Nursery, Boskoop, The Netherlands. This conifer is also known by a plethora of names, including 'Kosteriana,' 'Kosteriana Pendula' or 'Koster's Pendula.'

We think we have a Slenderina and are wondering if we ever need to prune it or just let the leader grow after it has reached the height we have staked it to.

it's really hard to prune spruce and have a satisfactory result. This species only does a single push of growth per year. If you mess something up, you'll have to live with the result for a long time.
