Print page

Latin name:Caltha palustris
Common name: Kingcup or marsh marigold
Type of plant: Marginal and bog plant
Hardiness: Hardy
Flower colour: Yellow
Height and spread: 25cm x 45cm (10in x 18in)
Description: Chunky British native plant with giant buttercup-like flowers.
Tips: Cut foliage down in summer if it looks scruffy, to encourage a neat new batch to set off summer-flowering marginals.
Latin name:Iris laevigata
Common name: Water iris
Type of plant: Marginal
Hardiness: Hardy
Flower colour: Purple
Height and spread: 80cm x 30cm (32in x 1ft)
Description: Architectural plants with fan-like foliage and spectacular, large, typical iris-shaped flowers produced in early summer.
Tips: Use where the foliage contrasts with bushier waterside plants as the flowering season is short.
Latin name: Lobelia 'Queen Victoria'
Common name: Lobelia
Type of plant: Short-lived marginal
Hardiness: Half hardy
Flower colour: Red
Height and spread: 90cm x 30cm (3ft x 1ft)
Description: Unlike bedding lobelias, it is a tall, upright perennial with purple-red leaves and red flowers.
Tips: A real eye-catcher deserving pride of place in your planting scheme, where its bold colours are set off by plenty of green foliage.
Latin name:Typha minima
Common name: Bulrush
Type of plant: Marginal
Hardiness: Hardy
Flower colour: Brown
Height and spread: 75cm x 45cm (30in x 18in)
Description: Miniature bulrush, with narrow reed-like foliage and short, stumpy brown heads in summer.
Tips: Leave plants standing as late as possible in autumn and winter for the shapes and bulrush seed-heads.
Latin name:Zantedeschia aethiopica 'Crowborough'
Common name: Arum lily
Type of plant: Marginal
Hardiness: Half hardy
Flower colour: White
Height and spread: 90cm x 60cm (3ft x 2ft)
Description: Architectural plants with large, arrow-shaped foliage and big white arum flowers in mid-summer.
Tips: Stand pots in deeper water than is usual for marginal plants. The layer of water insulates the roots in winter, protecting them from cold.
