Hardy Perennials

Artemisia stelleriana 'Mori's Strain' is a superior, dense, mat-forming selection. Uniquely shaped silver-white felted leaves with deeply divided, rounded lobes, it forms very attractive low mounds, giving an attractive ground-hugging carpet. Its foliage makes a wonderful foil for more colourful flowering plants.

Prized for its beautiful silvery foliage, the fine grey-white stems of Artemisia ludoviciana bear silvery-white leaves that are fragrant, fuzzy and soft. This finely textured plant adds a different element to the garden, the texture and leaf form setting them apart from those other garden plants with rather less refined foliage.

Aquilegia var. stellata 'Barlow Mix' is one of the really exceptional doubles forms of Aquilegia. It is the first Aquilegia series with fully double, spurless flowers. Stylish and elegant, with a graceful upright habit they grow to around 80cm tall. It produces many stems and makes an ideal cut flower.

Native to Canada and the US in all states east of the Rockies, this superb variety is quite unlike the usual Aquilegia. Growing just twelve to eighteen inches tall, with dark-green foliage and eye-catching, scarlet and lemon-yellow flowers which hang like drifts of softly illuminated lanterns.

Aquilegia atrata is a beautiful free flowering species that is native to the alpine meadows and forest clearings of Switzerland and Northern Europe. With many branching stems of deepest coloured, almost black flowers. This is an outstanding, highly sought species that would be a showstopper in any garden.

In addition to having one of the most unusual names, Antirrhinum braun-blanquetii, is also one of the few hardy perennial species of snapdragon. Named for Josias Braun-Blanquet an influential 20th century Swiss botanist it bloom the first year from seed producing numerous spikes from which delicate yellow, large snapdragon blooms appear.

Japanese Anemones are among the best late summer and autumn border flowers. The flowers open from round, silk-covered buds and in summer rain, look like pearls glistening in the border. Blooming from August to late October, they help push the show into autumn and provide colour when most gardens begin to fade.

Anchusa italica is a wonderfully statuesque plant with vibrant, gentian blue flowers, dense foliage and lance shaped mid green leaves. 'Dropmore' is a 1905 selection that is still available today. They will thrive in a sunny border and make a great companion to rich plums and purple tones.

Alcea rosea ‘Queeny Salmon’ is a knockout hollyhock, shorter, showier, and dressed in ruffled petals the colour of antique blush silk. It flowers its heart out in the first year from seed, the blooms are fully double, almost peony like, a beautiful soft pink that catches the light.

This gorgeous award winning Hollyhock has the distinction of being the shortest in the Alcea rosea family. 'Queeny' is a dwarf Hollyhock that reaches only 60cm in height with fully double blooms. Unlike the tall varieties, it is a perennial that can also be used as an annual as it will bloom in its first year.

Alcea ficifolia is reliably perennial and unlike the biennial forms which produce a single spire, they produce many upright stems, resulting in a bushy form. ‘Happy Lights’ is a beautiful strain, a bold blend of white, pink, purple, red, and yellow blooms. If sown early they will bloom in their first year.

For most of the year Ajuga is a pleasant, quiet achiever, a very versatile low growing ground cover, with evergreen, rosette-like foliage that hugs the ground like an evergreen carpet but those weeks in spring when the blue flowers appear are simply quite magical.

Ajuga genevensis is used throughout the world yet this relatively uncommon form is less well known. This very well behaved, evergreen groundcover has deep gentian blue flower spikes and is by far the showiest of the species. It is often the plant of choice for smaller areas or along edges and pathways.

Agave xylonacantha 'Blue' is the beautiful blue-green leafed form. Rare in cultivation, this dramatic specimen is armed with the most bizarre large white teeth of all the family. One of its previous names, Agave carchariodonta was in reference to the teeth (odonta) of the Great White Shark, Carcharodon carcharias.
