Hardy Perennials (Part 3)

Dicentra

Dicentra spectabilis

Now Lamprocapnos spectabilis, Bleeding Heart has become a popular addition to the cottage garden, its unusual flowers born on arching stems over fern-like foliage make an attractive show in early spring. Although it is one of the first border perennials to show it is worth noting that it is one of the first to die back in early autumn, so tends to look better in an informal setting. Thrives in any good moist soil in sun or partial shade but it does not respond well to being moved. There is a yellow leaved form available.

Dierama

Dierama pulcherrimum, Angel’s Fishing Rods are beautiful, evergreen perennials for an informal setting. They have arching flower stems covered in funnel shaped flowers in a range of shades of pink/purple and white over grass-like foliage. They prefer a sunny sheltered spot in moist soil and are another plant that does not like being moved although they actually grow from corms. Personally I have struggled to grow them and have only managed a few flowers at best, probably because my garden was too cold and damp. A member of the Iris family from South Africa there are many species and cultivars in cultivation including the well established Slieve Donard hybrids bred in N.Ireland.

Digitalis

Digitalis or Foxglove is a genus of both biennial and short lived perennial plants. The native Digitalis purpurea is common everywhere and well known, however some of the species and hybrids are less seen. Broadly speaking, being woodlanders, they all prefer a moist soil in dappled shade although D.purpurea seeds itself almost anywhere and I have had an excellent plant growing from a shady rock crevice in the past. Pam’s Choice is a naturally occurring garden hybrid found by a keen amateur gardener.

Draba

Draba cuspidata

Drabas are alpine members of the brassica family and originate from Central Europe and even the UK, they are cushion or mat forming plants, the most common garden specie being Draba aizoides. As with most alpines they like a gritty open soil in a sunny position. The plant pictured above was grown from a “lucky dip” collection of society seed out of curiosity.

Epimediums

Epimedium grandis

Epipactis hardy orchid

Epipactis helleborine

I have included this for its novelty value, possibly Epipactis helleborine, I am no expert when it comes to orchids, just seeded itself into my ‘woodland’ garden, flowered and disappeared.

Eryngium

Eryngium giganteum ‘Miss Willmott’s Ghost’

Eryngium giganteum or the Giant Sea Holly is colloquially associated with Miss Willmott of Warley Place, who by all accounts was a formidable lady, because of a story in which she was said to scatter the seed of the eryngium in any garden that she visited that she considered to be dull. Unfortunately the story has been debunked in recent years. Eryngiums are basically thistles and require a sunny spot in well drained but moist light soil to grow well. There are several cultivars available ranging from silvery white to steely dark blue.

Eupatorium

Common name Joe Pye Weed, this is a fantastic plant for adding height and late colour to the border, growing to over 6′ its purple flower heads remain until the first frosts. This is one plant that I have introduced to my new garden, late to surface, its flowers have been covered in butterflies and other insects since the end of June and it is still going strong.

Eupatorium rugosum ‘Chocolate’ is a different plant altogether smaller in stature with dark green/red leaves and contrasting fluffy white flower heads it is rather striking. Now reclassified as Ageratina altissima which just doesn’t have the same ring to it somehow.

Euphorbia

Euphorbia or Spurges are a massive and diverse genus ranging from annual weeds to trees, with shrubs and even succulents in between. The plant above is a typical garden cultivar the many species and cultivars have a range of colours including acid green and even orange. A well known member of the genus is the popular Christmas plant the Poinsettia (Euphorbia pulcherrima). The plant that is getting all my attention at the moment is the annual garden weed Euphorbia peplus, it only appeared a couple of years ago and is proving to be a nightmare! All of them, that we are likely to come in contact with, have a toxic sap which can cause painful blisters on someone who is sensitive.
