Picea glauca (common name White spruce) is another native spruce that is hardy to the far north (Zone 1).
Picea glauca ‘Dent’
This picea has white spring growth that is quite striking. My plant is about 2 m high, but because of neglect and crowding over the years, it developed a very loose habit. I hope to gradually correct the shape and try to get a better picture next season.
Picea glauca ‘Golden Kling’
If I remember correctly, this plant was acquired form RBG plant sale many years ago. As far as I can tell from the name tag, it is Picea glauca ‘Golden Kling’, but I cannot find any information for such a name on any sources. It appears to be a small plant with somewhat weeping habit. The most interesting feature is the creamy golden colour foliage from spring to summer.
Picea glauca ‘McConnell’s Gold’
It has beautiful creamy golden foliage in spring. Its growth rate is expected to be 4-8 cm/yr. Found by Joe Stupka at a Christmas tree plantation owned by Dick McConnell situated near Edenburg, PA (from Edwin of Netherlands).
Picea glauca var. albertiana ‘Conica’
I used to use this as bonsai, and the remaining stocks were spread around the garden everywhere. As it turns out, this is one of the most useful plants for use in garden. It can take full sun to full shade, grows slowly, hardy and requires no maintenance (other than watch out for spidermite). It can get winter burn from extreme cold wind facing south in full winter sun, but usually it manages to recover in a couple of seasons depending on the severity. It has a tendency to have some branches revert to the species, and if not prune away will eventually take over the whole tree.
Picea glauca var. albertiana ‘JW Daisy’s White’
This is the more commonly available Alberta spruce with white/cream new growth. It is quite a sight to see a conifer completely covered in cream colour foliage in spring. The colour will eventually fades to the normal light green similar to the common Alberta spruce. I think its growth rate is much slower than the normal Alberta spruce.
Picea glauca var. albertiana ‘Pixie’
This is a very dwarf form of Alberta spruce that is very much at home in a rockery garden.
It was found by W.Goddard of Canada.
Picea glauca var. albertiana ‘Rita’
This plant is supposed to have creamy spring growth similar to ‘Daisy’s White’ but probably slightly more yellow. It is still young, and is going to be a nice dwarf conifer. It was a gift from Darren of Whistling Gardens.
