It is a pretty shrub conifer from Europe that has been offered by most conventional nurseries in the Midwest and East USA for decades.

The mother species here is slow growing of about 3 to 6"/year, but slowly can get to about 20 feet high eventually. I've seen some really huge ones in cemeteries 15 to 20 feet high. One can prune them back in late May or early June to keep them small for a long time; just don't ever cut below where there are green needles (the green zone). Cut off most of the candle growth in late spring is best. This species does get powerfully and commonly attacked by European Pine Sawfly that eats up the needles and by Pine Scale insects that look like white specks on the foliage. A number of dwarf cultivars are now offered, but still will need some pruning back.

Very susceptible to pine sawfly.

I have read in books that this plant was in introduced in the US from Europe in 1779. Pinus mugo or Swiss Mountain Pine is a shrub to ab...Read Moreout 3.5 meters tall (this varies) in its mountainous native habitat of central Europe, eastern Spain, and the Ukraine. This pine is root-hardy in most areas and thus useful as a container plant or Bonsai.

'GNOM' Very dense, globose habit, with a good deep green color. A 35 year old plant was about 4 meters high and broad. Distributed in 1927 by den Ouden & Son, Boskoop Netherlands. Very hardy. H:4' W:4'

'MITSCH MINI' This cute little bun-shaped plant is one of the slowest growing of all dwarf conifers and was selected by John Mitsch of Aurora Oregon. The needles are light green and both them and the branches are very short creating an impression of a clump of moss.

'MOPS' Mugo Mops is a very slow growing selection with a dense and globose habit becoming nearly as high as broad. It has been in cultivation since around 1951 and was distributed by Hugo Hooftman from Boskoop, Netherlands. The height after ten years is 30" high and 3' wide.

'WINTER GOLD' A low, wide and open growing plant to about 1 meter. It turns an attractive bright golden-yellow color in winter. Nice accent plant. It originated before 1969 in the Draijer B. V. Nursery, in Heemstede, Holland.

Mugo pines are used extensively in this area for screens and hedges. They can grow to over 6 feet tall but can be controlled by pruning....Read More They provide some much-needed colour during the long winter and look great with a bit of snow on them. They also provide habitat for birds.
