Hellebore 'Blackthorn Strain' is a carefully selected seed strain, with delicate pink flowers backed with pink and green, the stems, petioles and often the anthers are an enchanting ripe berry rose. The saw-toothed foliage is pewter-blue above, burgundy-grey beneath.

Originating from one of the country's top hellebore breeders. Hellebore 'Black Beauty' is a choice variety. The deepest plums and purples open from slate coloured buds, many plants having the extra bonus of the dark foliage of their parents.

Based on hybrids bred by the doyenne of the Hellebore world, Helen Ballard, these must be some of the finest and most beautiful of the race we have to offer. Large flowers are produced in a variety of colours from dark purple to white - often extravagantly mottled and marked.

Herniaria glabra is a relatively unknown perennial that deserves to be used more often in our gardens. The nursery industry calls it ‘Green Carpet’ and well they should. This lovely bright green creeper spreads effortlessly in all directions. An excellent choice for between flagstones or as a lawn substitute.

Compared to the traditional candytuft, this beefy species offers a decadent flower display. In mid spring, the whole plant disappears under an abundance of flat, light violet to pinkish white blossoms, creating a lasting mound of colour. Iberis gibraltarica is a lovely plant for rock gardens and well-drained borders.

The Kniphofia hybrids have extended both the flower colour and height range. The usual fiery reds and oranges work particularly well in a planting scheme based on 'hot' colours - use them to light up sultry August borders. The cooler yellow, cream, ivory and sometimes green flowers is more restful.

Lavendula angustifolia is an excellent plant for low informal hedging and as a specimen evergreen for borders and formal gardens. Flowering generally begins from mid to late June to early July. The flowers have a rich sweet scent and are highly attractive to bees and other beneficial insects.

The development of bananas is a source of both pride and amazement to those unfamiliar with banana culture. Musa acuminata is a 'dwarf variety' with broad, long, graceful leaves, and is extremely suitable for containers or gardens.

Musa Balbisiana is a fruit bearing variety and one of the progenitors of the present-day commercial bananas. The clumps of lush, dark foliage make it ideal for creating a jungle landscape. It develops large colourful inflorescence of bright red and maroon.

Despite its American provenance Panicum virgatum was originally taken up by German landscapers and gardeners. Renowned for its steely coloured blue-grey to blue-purple leaves, but it is the contrast between the rigid, stainless-steel foliage and purple-pink froth that really charms.

'Emerald Chief' is a good Panicum virgatum selected seed strain. Hardy with sturdy upright deep green growth and great autumn colour. The panicles open red pink in late summer and its foliage turns from green to a lovely deep gold. This chief stands up tall throughout the winter months.

A Passiflora that produces very fragrant, unusual flowers. The flowers are white, except the base of the corona which is purple; the filaments are curly, as long as the petals, 5 to 7cm across. The edible fruits possess pleasant flavour, kind of sweet and a little tart.

With their arching, strappy, sword-shaped leaves, Phormiums make a dramatic statement in the garden. They are versatile evergreen plants that tolerate a range of conditions and look at home in a variety of different planting schemes.

Rosularia is a rosette forming succulent that closely resemble other Crassulaceae such as Sempervivum and Echeveria. It distinguishes itself in spring time when the small green clusters change to a vibrant rich reddish tone. Rare yet hardy, they are seldom seen other than in specialist nurseries or rock garden collections.

Sagina subulata is one of the best low growing ground covers. Irish moss is most often used as a ground cover, softening paths and stepping-stones. It gives a lush accent to rock garden and terraces. For a luxurious carpet of green, few plants can match Irish Moss.

Saxifraga x arendsii 'Purple Robe' are compact, free-flowering, and easily raised from seed. These charming perennials quickly form an evergreen verdant mat. Excellent as alpine plants for a rockery or trough, use them spilling over low walls, as a path edging or green roof.
