The Royal Series is the only Aubrietia awarded the RHS AGM. This soil hugging perennial carpets the ground in a profusion of bloom early spring. Plant in crevices of walls or on a steep bank to flow over into a waterfall cascade of colour. RHS AGM.
Pomponette Mix boasts masses of tightly quilled 4cm button, fully double flowers on neat, compact plants. They bloom repeatedly from late winter to late spring in vibrant shades of red, rose and white.
This dwarf Marigold flowers earlier than most other varieties on vigorous, bushy plants. The stunning double flowers provide an array of both single and bi colours, range in tones from creamy yellows and rich tangerines to vibrant oranges and warm reds.
Campanula Pusilla is distinguished by its production of enormous numbers of elegant, lavender-blue bell-shaped blooms. It grows horizontally with rosettes of shiny green heart shaped foliage, rarely exceeding 10cm in height. It will spread indefinitely.
'Helen Campbell' is a particularly attractive variety which produces scented white flowers throughout the summer The extraordinarily long stamens protruding from the scented flowers and the long seed pods, give the flowers its spidery appearance.
Cobaea scandens is an impressive climber and is one of the fastest-growing and most trouble-free vines you will ever grow. Extremely attractive when scrambling upward through trellis work, archways, over small buildings or old trees.
Cobaea scandens alba will appeal to anyone who longs for something with panache and visual impact. This rare variety has clear white flowers and will fill the air with a very pleasant honey scent throughout the growing season.
I like magnificence in the garden. Either those plants which over perform, or those which are so rare that they stop one in ones tracks, or those that designers call 'statement plants'. Crambe cordifolia is one such plant. All about stature, plant them and stand well back.
Give the devil his due Crocosmia has never looked more appealing. 'Lucifer' is an aptly-named variety because its flowers are the hottest coloured of all - a searing paprika red. The fiery-red flowers with orange-yellow throats are held on gently arching stems.
Cyclamen coum is adored as a cultivated ornamental plant. The flowers vary from white to rosy-purple with every hue in between and sometimes of such quantity to obscure the leaves. The dainty blooms open from early winter and continue unabated into spring.
Ivy-leaved cyclamen, Neapolitan cyclamen. Wildflower of the British Isles
There are few plants that offer such ornately decorative foliage. no two plants are the same and a mass planting of Cyclamen hederifolium in the late autumn or winter is more fascinating than the most intricately detailed Persian carpet.
Whether you are into the culinary arts or edible landscapes, you may want to put this plant at the top of your list. Chosen by the RHS as one of the top plants of the last 200 years, Cardoons are aristocrats in both the ornamental and the vegetable world.
Sweet Williams are one of those lovely old-fashioned flowers, easy to grow and famous for their spicy-scent. The Auricula-eyed Group are irresistible, dense clusters of flowers in patchwork colours, dark tapestry rubies, fuchsia, scarlet, purple and white.
D. spectabilis features nodding, pink heart shaped flowers which dangle enticingly from arching flower stems. Planted with other shade lovers, it can easily be the most breath-taking showstopper in the garden when in full growth.
