There are several cultivars that are related or similar to ‘Squarrosa’, but there seems to be a good deal of confusion on the names.
- ‘Squarrosa Aurea’ - outer yellow leaves against greenish-blue inner leaves, dwarf, slow growing to a rounded, slightly upright plant, to about 3 ft (0.9 m) in 10 years.
- ‘Squarrosa Intermedia’ - a bluish, semi-dwarf form, produces long shoots and needs trimming.
- ‘Squarrosa Lutea’ - sulfur-yellow foliage, grows slowly into an irregular globe, eventually 3-4 ft (0.9-1.2 m).
- ‘Squarrosa Minima’ - miniature globe-shaped form, less than 1 ft (30 cm) in 10 years, olive-green foliage.
- ‘Squarrosa Sulphurea’ - sulfur-yellow foliage, especially in spring, globe shaped shrub, dense.
- squarrosa: from the Latin meaning rough, with reference to the scaly leaves which spread outward.
