A simple and elegant member of the buttercup family, forming vigorous clumps of many branching stems, which carry single white flowers with a yellow centre. 90cm (3ft) high. For good to moist soil in sun or partial shade.

Known as Fair Maids of France, originating in the moist mountain meadows and open woodland of Central Europe. A truly superb plant with double white flowers on attractive branching stems to 60cm (2ft) or more high.

Anyone who knows me will also know how I love buttercups in any form! And what a gem this one is double yellow flowers like little buttons held on wirey stems to 18" in height.

This pale-flowered form of our native Meadow Buttercup has a subtle beauty and charm. Its flowers are freely produced in May to June, on stems 30-60cm (1-2ft) tall, each individual flower of the palest shining lemon-yellow. Do not allow to self sow otherwise the resultant seedlings will be a mix of predominately typical yellow flowers with only the odd pale yellow thrown in. A moisture-retentive soil is best

Possibly the best of the double flowered varieties, with nicely restrained foliage adorned with delicate pale green to silver dappling and tight rosettes of double yellow flowers.

A real curiosity on the nursery, double flowered miniature "roses", sappy green in colour and displayed against silver marbled foliage.

A perennial from Europe, with large, pale green, hairy leaves appearing in late winter followed by large, yellow, cup-shaped flowers in spring. Prefers a hot dry site. Dies back during summer. 30-45cm (12-18").

A fantastic pool margin or bog plant, happiest with its feet in water, where it will produce masses of large, shiny-yellow, five-petalled flowers throughout summer. A native of Britain and Europe up to Siberia.120cm (4ft).

A clump forming perennial, suitable for the rock garden or herbaceous border and cultivated for its glaucous foliage and bright yellow starry flowers. 30cm (12").

Attractive bold, bronzed foliage and rosy flower heads in summer. 90-120cm (3-4ft) in height.

A statuesque and handsome foliage plant, producing large heavily corrugated foliage in spring, at the time it is reddish-purple in colour changing by mid season to a strong green before ending the season with a spectacular display of autumnal tones. During midsummer it adds to the display by producing tall spikes of creamy-green, star-shaped flowers appearing well above the foliage. 75cm (30").

A wild collected plant, the new growth is a wonderful rich cinnamon-brown colour which is followed later in the year by tall, elegant creamy flower spikes. 90cm (3ft).

A particularly good form of rosemary, with strong upright stems and freely produced light blue flowers.

Medium sized clear, cadmium-yellow flowers with a dark eye, on long stems in later summer and well into autumn. A most cheerful plant and very rewarding to the grower; ideally suited for a sunny site, where the bees and butterflies can also appreciate the flowers. 90cm (3ft).

Large golden yellow flowers with a black centre. A very sturdy plant and robust grower tolerant of many situations but revelling in an open site. Long lasting blooms are great for cutting and bringing into the house. 60-75cm (24-30").
