Picea glauca'Pendula' is a graceful, narrow-upright selection of White spruce with a strong central leader and steely Blue foliage on stiff, strictly pendulous branches that cascade down the trunk and flare out slightly at the tips. After 10 years of growth, a mature specimen will measure 10 feet (3 m) tall and 3 feet (1 m) wide, an annual growth rate of 1 foot (30 cm).
This cultivar originated as a spontaneous weeping mutation found in the 1860s in Trianon Park, Versailles, France. French botanist, Élie-Abel Carrière formally described it in botanical literature in 1867 in Traité Général des Conifères. In the Latin language "pendula" translates into "weeping or pendulous."

I have a question. I was told that it was a slow grower and that you could trim the leader back. How much can I trim back and when can I trim it?
Hi Linda ... you were told wrong. I've seen this one put on a foot or more of growth every year. Typical mature specimens measure upwards of 20 feet tall. Pruning spruces is an art form in itself. It's very difficult to do and rarely comes out right. Honestly most people don't even try to do it. I especially recommend not messing with the leader.
I recently planted a tree that was tagged weeping white spruce, however I was told it was a Weeping Norway Spruce. Upon some research I see they are quite different. On the tree I have the top (I think its the leader) is hunched over and not growing upright. Is this ok, should I be doing anything to help it along or straighten it?
Hello Lisa. You are correct in the Picea glauca 'Pendula' and Picea abies f. pendula grow with very different structure. It sound like you plant is knuckled over. That leader will eventually reach the ground and start rambling around. At this point in the season, the new growth has likely hardened off to the point that, if you try to straighten it, it'll break.
The best you can hope for is to stake up a weaker branch which may or may never achieve apical dominance. Also be aware the weeping Norway spruce will only grow to the top of its highest stake, then knuckle over once again.
I have a Weeping White Spruce that I think has reached maturity because even the leader is now weeping. My question: Can I remove the fence I've had around it for protection from deer? or will the deer graze the lower branches destroying the characteristic look? Thank you.
