Description and Cultural Plant Tips

This is a dwarf blue  spruce that grows no more then 2 - 3 inches a year. It has a rounded shape and needs little pruning. It can be used as focal point in a shrub border, rock garden  or as a low hedge.

Plant slightly above soil grade in well-drained, slightly acidic soil. Mulch top of soil in a 2 -3 foot diameter circle. Water regularly until established, afterwhich, water requirements are low. Needs little to no pruning.

No serious diseases. Can attract aphids. See UC IPM for treatment options.

Master Gardener Comments

I now have three of these blue spruce in my shrub borders. They are a beautiful blue and look good with the various greens and golds of the other shrubs. They never need pruning and grow very slowly. I have one that is 20 years old and it is only 4 foot high. They have had no pests or diseases worth noting.

Varietals

P. a. Nidiformis - "Birds Nest Spruce", very compact with dark green foliage and grows as a flattened globe, much like a birds nest. Grows very slowly to 3 foot tall.
