Anemone × hybrida ‘Honorine Jobert’

Anemone × hybrida ‘Honorine Jobert’

Japanese Anemone

10365766861111|Anemone × hybrida ‘Honorine Jobert’|Japanese Anemone|

A robust, upright Japanese anemone valued for its late-season presence and clear white flowers held well above the foliage. The simple blooms are centered by a bright yellow boss of stamens and appear steadily from late summer into autumn. Vigorous and long-lived, this is a dependable border plant that brings structure and light to the garden as earlier perennials fade.

Anemone x hybrida 'Königin Charlotte'

Anemone x hybrida 'Königin Charlotte'

Windflower

10365766893879|Anemone x hybrida 'Königin Charlotte'|Windflower|

A tall, vigorous anemone producing soft pink, semi-double flowers on upright stems from late summer into autumn. Similar in stature and garden presence to ‘Honorine Jobert’, but distinguished by its fuller flowers and warmer colouring. It provides reliable height and movement in borders at a time when many perennials are finishing.

Anthemis tinctoria ‘E.C. Buxton’

Anthemis tinctoria ‘E.C. Buxton’

Chamomile

10365766926647|Anthemis tinctoria ‘E.C. Buxton’|Chamomile|

A long-flowering selection of Anthemis tinctoria, producing a steady display of pale yellow, daisy-like flowers from early summer until frost. In lean, well-drained soils it forms a strong, upright clump and maintains its flowering momentum over a remarkably long season. In wetter climates, an early autumn cut-back helps ensure reliable performance the following year.

Anthemis tinctoria ‘Sauce Hollandaise’

Anthemis tinctoria ‘Sauce Hollandaise’

Chamomile

10365766959415|Anthemis tinctoria ‘Sauce Hollandaise’|Chamomile|

A cream-flowered selection of Anthemis tinctoria, forming an upright clump and flowering steadily from early summer until frost. It shares the same long season and reliable performance as ‘E.C. Buxton’, particularly in lean, well-drained soils. In wetter climates, an early autumn cut-back supports continued vigour and flowering in subsequent years.

Anthriscus sylvestris ‘Dial Park’

Anthriscus sylvestris ‘Dial Park’

Cow Parsley

10365766992183|Anthriscus sylvestris ‘Dial Park’|Cow Parsley|

A dark-leaved selection of cow parsley with foliage deeper in colour than ‘Ravenswing’, forming a rich purple mound early in the season. Airy white umbels appear in late spring, carried above the foliage on open, branching stems. Plants self-seed freely, and selection of seedlings is required to retain the darkest leaf colouring.

Anthriscus sylvestris ‘Ravenswing’

Anthriscus sylvestris ‘Ravenswing’

Cow Parsley

10365767024951|Anthriscus sylvestris ‘Ravenswing’|Cow Parsley|

A striking spring perennial grown for its dark, mahogany-toned foliage and airy white umbels held on open, branching stems. The foliage forms a low mound early in the season, with flowers appearing in late spring before the plant begins to fade. Raised from seed, ‘Ravenswing’ will self-seed, and seedlings should be assessed to retain the deepest leaf colouring.

Aruncus dioicus ‘Whirlwind’

Aruncus dioicus ‘Whirlwind’

Goat’s Beard

10365767319863|Aruncus dioicus ‘Whirlwind’|Goat’s Beard|

A large, clump-forming perennial valued for its bold foliage and tall, plume-like white flowers in early summer. ‘Whirlwind’ develops into a substantial plant, best suited to moisture-retentive soils at the margins of woodland or in generous borders. Given adequate space and moisture, it forms a durable, long-lived presence rather than a compact accent.

Aruncus dioicus ‘Liz’s Goat’

Aruncus dioicus ‘Liz’s Goat’

Goat’s Beard

10365767287095|Aruncus dioicus ‘Liz’s Goat’|Goat’s Beard|

A refined selection of goat’s beard noted for its balanced, upright habit and finer texture than the species. It forms a leafy, bush-like clump that remains effective well beyond flowering, particularly in woodland conditions. The flower plumes are shorter and more restrained than typical forms, giving the plant a quieter, more foliage-forward presence through the season.
