Zone 3.
Juniperus horizontalis ‘Hughes’ – A very low growing Juniper which makes it ideal for mass planting, the silvery-blue foliage forms a dense ground-hugging mat which turns a light purple in the colder winter weather. ‘Hughes’ looks great on embankments or even trailing over walls and rarely needs pruning except to contain the planting edge. Grows 12-15″ high by 6-8′ wide. Z3.
Juniperus chinensis ‘Pfitzeriana Aurea’ (syn. Juniperus x media) – A taller Juniper cultivar which is excellent for smothering weeds with its dense growth habit.

Grows 4′ high by 6-8′ wide. Hardy to zone 3.
Juniperus sabina ‘Scandia’ (syn. ‘Skandia’) – Another of the ground-hugging Junipers with bright green foliage year around. It is a good choice for stabilizing slopes or mass planting and is often found in commercial landscapes due to its durability. ‘Scandia’ is quite drought tolerant once established and is suitable for Xeriscape gardens. Grows 12-24″ high by 6-7′ wide. Zone 3.
Juniperus horizontalis ‘Gold Strike’ – Absolutely brilliant gold new growth tones down to chartreuse by summer and only gets better in winter when it shifts to coral-pink tones. It is a sport of ‘Mother Lode’ that may scorch in full sun in interior landscapes. The growth is somewhat mounded but it still makes a great groundcover. Grows 6″ high by 3′ wide in 10 years. Zone 3.
