Larger agave, but still slow growing like most in a temperate climate. Attractive blue tinged erect saw toothed leaves.
Clumping plant for clay, pond margins or moist soils. Attractive tall pink fluffy flowers, over palmate foliage. Cut back after flowering to the ground and it will resprout when the conditions are right.
Upright intermediate between 'Autumn Joy' and 'Purple Emperor', green foliage infused with purple, darkening as the season progresses. Rich pink and rose colours late in summer, wonderful amongst grasses and salvias.
White outward-facing bell flowers clustered on tall stems over a rosette of bright green foliage make this a very attractive garden plant. A suitable ground-cover for colonising difficult areas, particularly in the wild garden where it can be left to ramble freely.

Old fashioned cottage plant with intense blue flowers, easily grown but best in clay based soil.
Leafy plant from saxifragaceae family, useful for ground cover in dry shade where acanthus and euphorbia can take over. Good drainage and neutral to alkaline soils preferred.
