Plants for Damp Shade
There are a number of plants and shrubs which will survive in, and be happy in damp shade. These are not bog plants but plants which tolerate partial shade conditions which are damp as opposed to dry shade.
Illustrated above centre is Digitalis purpurea, Foxglove of which there are several varieties including a pure white 'Alba'. Digitalis will grow in sun or shade and will grow where it is damp. They are biennials which flower in the summer and will self seed around the garden to produce new flowers year after year. Digitalis are easy to grow - more tips on growing Digitalis. One cautionary note is that all parts of Digitalis are poisonous.
Illustrated left is Hosta well known for being shade and damp tolerant, some varieties more so than others. Ideal Hostas for damp shade are H.fortunei 'Albomarginata' large Hosta 75cms with green and white ivory variegated leaves; H fortunei albopicta large 75 cms variegated hosta ; H.'Frances Williams'(sieboldiana) smaller 60cms blue green leaves; H. 'Halcyon' smaller Hosta at 30cms blue leaves. Hostas are generally easy to grow; more tips and images on growing Hostas
Illustrated centre is Fritillaria meleagris, the snakes head fritillary, a bulb happy to grow in shade and quite wet soils, see below.
Many of the plants listed below are easy to grow and are labelled green wheelbarrow More difficult plants are labelled an amber wheelbarrow means more difficult to grow.
Ideal plants for Damp Shade
|Fritillaria meleagris common name Snake's Head Fritillary is a lovely delicate bulb which flowers in spring and has chequered bell like flowers in shades of purple and F. Alba a white variety both are fully hardy. Good in damp soil and will tolerate some shade they are easy to grow and once established will multiply and populate a suitable damp area of the garden and come up reliably each year. They are low growing up to 25/30cms.|
|Persicaria common name Bistort commonly grown are P.affinis, P bistorta, P. milletti (image left) all have flower heads which are spikes and in varying forms of pink, and reds. All have a preference for damp soil and will tolerate partial shade, Bistorta is the most commonly found and has the RHS award will flower for a long time in the right conditions can be slightly invasive towards plants around but ideal clump forming maintenance free perennial plant.|
A number of Hellebores are suitable for damp shade and make a lovely late winter and early spring display. Helleborus orientalis 'The lenten Rose' is particularly attractive as is the H. Niger 'The Christmas Carol' both are tolerant of shade and damp soil . Hellebores make a neat clump and are generally trouble free apart from a risk of black spot. They look particularly good in a wood land setting such as under planting Rhododendrons, some of which will grow in shade.
Hellebores are easy to grow plants which spread and self seed in a well-behaved way; tips and advise on growing Hellebores. They are also suitable for growing in containers for winter bedding scheme.
|Pulmonarias, image left, are ideal and tolerant of damp shade. They are a small, low growing, late winter flowering perennial which are good for ground cover. Pulmonaria are also a good source of nectar for bees emerging in late winter. Pulmonarias are easy to grow and form neat clumps if left undisturbed. They are generally blue, pink or white and look good with early flowering spring bulbs. Pulmonarias usually flower around February.|
Cornus, common name 'dogwood', are an easy to grow deciduous shrub which have great winter colour with striking red stems as illustrated left the variety Cornus Alba and also 'Elegantissima' and 'Sibirica' for good winter red colour, and Cornus sericea 'Flaviramea' for yellow stems.
Cornus have a lovely variegated leaf and creamy white flowers in late spring and summer. To maintain the winter colour Cornus are best cut back hard every one to three years in early spring to make sure of strong colour in the stems for the following winter. The stems are coppiced, that is to say cut to the ground. Cornus are easy to grow, trouble free and an ideal shrub for a damp area of the garden.
Cornus are often grown for winter colour on the stems look best if grouped and grown together on mass.
Alchemilla mollis will grow in partial shade and damp conditions. Alchemilla is a herbaceous perennial and very easy to grow but carries a warning as it is a vigorous self seeder and will pop up everywhere once established. It is not difficult to remove or thin out and in situations where ground cover is needed it can be very effective. Alchemilla looks good growing with Primula many varieties of which are also tolerant of these conditions.
Alchemilla can look a bit ragged and tired later in the growing season. To improve this cut back all of the foliage right to the ground and it will rapidly replaced with fresh green foliage for the rest of the season. If the plant looks brown and tatty around late June/July be bold cut back and within a couple of weeks it will look fresh again.
One of my absolute favourite plants, which is so colourful and graceful, is Thalictrum, the variety illustrated and good for partial shade and damp conditions is T. delavayi. It is a tall, herbaceous perennial which comes up reliably every year. The variety illustrated is 'Alba' but more common and widely available is its purple variety, which produces tiny fluffy purple flowers and tall stems which sway around in the breeze and need no staking. There is so much to recommend Thalictrum, tall and graceful, lovely flowers leaving attractive seed heads. More about growing Thalictrum and images of this delightful plant which is so easy to grow.
|Astilbe is a great plant for damp conditions and is tolerate of partial shade. Astilbes come in many different colours mainly pinks, purples white and cream. The Astilbe illustrated, Astilbe 'Professor van der Wielen' is a bright white variety and like all Astilbes, easy to grow. Astilbe will flower reliably for many years and is good value for money. Astilbes look good with ferns many of which are tolerant of shady damp conditions. The flower heads are soft and fluffy and a good mix in the border. An easy to grow reliable plant which needs no real attention or maintenance.|
|Meconopsis Grandis 'Branklyn' the Himalayan Blue Poppy is a stunning plant but not easy to grow and can be short lived. It needs a sheltered shady spot in moist, acid soil. It will not tolerate warm dry spots. It is a native of Tibet where summers are cool and wet and winters cold and snowy which are the conditions it is most happy in. It is ideal in a woodland garden, a shady area and will tolerate coastal conditions. Meconopis grow to around 1m, it is summer flowering and fully hardy. Meconopsis can short lived and if grown in a dry spot will be Monocarpic, i.e. die after flowering so the right spot is crucial. Some varieties are Monocarpic by nature and so selecting a variety is important. M. betonicifolia and grandis are not by nature monocarpic and have the RHS garden merit award and would make a good choice. The Himalyan Blue Poppy is a plant which thrives better in the norther parts of British Isle and Scotland as it likes conditions which cooler and wetter. Recommended varieties with award of garden merit are M.baileyi, M 'Jimmy Bane', M. 'Huntfield' and M. 'Barney's Blue' It is a bit tricky to grow rated amber wheelbarrow|
