  1. CYCLAMEN LIBANOTICUM

    Early in the year white or pale pink flowers open which gradually deepen in colour to a clear brilliant white. Possibly hardy in the warmer parts of the UK, it is best grown in an alpine house. It has in recent years proved to be quite hardy, tolerating temperatures as low as -12ºC in a sheltered, well-drained spot, but it will not tolerate both low temperatures and wet conditions. ...

  2. CYCLAMEN MIRABILE

    This species has attractive leaves often marked in pink or silvery-grey, and bears in autumn, pale pink flowers with a small purple basal blotch. These are generally sub-orbicular with shallow dentations at the margins. The upper surface often has silvery markings, but very often there are carmine-pink zones which are especially pronounced when the leaves are immature, and often ages to a silvery grey. In some forms the red colouring covers the entire surface of the leaf, ageing to an allover silver wash. This form is available in cultivation under the name C. mirabile 'Tilebarn Ann'. An intermediate form with a dark Christmas Tree shape in the centre, surrounded by a wide pink/silver band is named C. mirabile 'Tilebarn Nicholas'. ... Learn More

  3. CYCLAMEN PERSICUM

    These wild plants have large heart-shaped leaves, sometimes up to 3 or 4 inches across, usually green with lighter marbling on the upper surface. Very fragrant flowers bloom from winter to spring (var. persicum) or in autumn (var. autumnale) and usually white to pale pink flowers with a band of deep pink to magenta at the base, plants going dormant in summer. It is principally a tender plant which will not tolerate frost, but grown under glass it survives temperatures as low as -2ºC provided the leaves are dry. In pots, the tubers will grow in size quickly and it is common for them to reach a diameter of over 15cm (6 inches). ... Learn More

  4. CYCLAMEN PSEUDIBERICUM

The spring-blooming flowers have five reflexed, up-swept petals, and are fragrant and magenta-purple or pink, and have a darker blotch and a white zone at the end of the nose and is hardy to -15 C. In the UK it is usually grown in pots but will grow in sheltered spots outside. It has been given the Royal Horticultural Society's Award of Garden Merit. ... Learn More

  9. CYPELLA HERBERTII

    This exotic-looking beautiful flower opens in a quite unusual shade of french mustard! The individual flowers open for just a day or so, and then another flower opens on the same stem, making a long display as long as buds are produced. These plants will perform well in dryish warm screes but excel themselves in a container when they can multiply up. In the wild they are found from S. Brazil to N.E. Argentina. Few seeds collected. ... Learn More

  10. CYPERUS ALTERNIFOLIUS

    The "Umbrella Plant" makes an attractive feature in a bright window or sun lounge where it produces strong stems topped with striking umbrella-like spokes. On mature plants, sprays of white flowers appear. It may also be used as an impressive marginal plant in a pond or bog garden. If planted deeply it will survive the average winter although is best given winter protection. It is a native of the swamps of Madagascar and a relative of the famous Papyrus of the Nile river and is also sometimes called Umbrella Papyrus, Umbrella Sedge or Umbrella Palm. ... Learn More

  11. CYRTANTHUS BRACHYSCYPHUS

    Above narrow foliage arise slender, wiry stems, holding clusters of up to ten long-lasting, very bright, orange-red trumpets, which will re-appear throughout the summer, especially if watering is stopped for five or six weeks, then restarted. Intense, flaming orange is not a frequently encountered colour among the smaller bulb species, but this is a superb and glorious exception, an established plant with multiple flowering stems being a joy to behold. Although quite rare, this is one of the easier ones to grow. In the wild they are found in moist grassland or rocky stream banks in the Eastern Cape and KwaZulu-Natal. They are best planted in frost-free conditions, in a fertile well-drained loam soil with the necks at the soil surface, or in a frost-free container. ... Learn More

  12. DACTYLORHIZA PURPURELLA

    This beautiful flower is widespread in the British Isles where it is found at up to 600 m above sea level. It is the more northerly equivalent of D. praetermissa with a delightful stocky dwarf habit with deep blue-tinged, green leaves and compact crowded flower spikes of deep rich violet-purple flowers. The individual blooms are deeply coloured and have a characteristic diamond shaped lip. It grows well and bulks up, doubling annually in ordinary garden soil, which is ideally damp but well drained. ... Learn More

  13. DAHLIA AUTUMN DAZZLERS

    New! Dahlia australis, the true species, is a magnificent plant, with demurely nodding pink to lilac flowers, (which are bigger than the similar D. merckii, which is less vigorous and of smaller stature.) Sadly, we have found that it can be difficult to keep year on year. But one day, we discovered that the busy bees at Plant World gardens had pollinated a Dahlia australis plant with pollen from other lovely dahlia cultivars in our gardens. And what an amazing surprise we received when this handful of seeds germinated and finally flowered! A completely new generation of tall but elegant dahlias with numerous branching spindly stems, offering months of a complete spectrum of vibrant colour with surprisingly little effort. These will flower their heads off in virtually any sunny spot, until the first frosts cut them down. Almost constant-flowering, these lovely single flower forms, with the occasional dark-leafed specimen, make solid, stately, almost shrubby plants, which are very easy to integrate into the average garden border, and appear to be quite hardy, having survived for ten years outside untouched by winter. Not prolific seed producers but worth any trouble to grow. ... Learn More

  14. DAHLIA CACTUS HYBRIDS MIX

    Cactus Dahlias make for an impressive display, bearing curvaceous, spiky blooms in a range bright colours. Their star-shaped flower form means they stand up well to inclement weather, because they’re less prone to being weighed down by heavy rain, or blown about by wind, than other Dahlia types. They are easy to grow from seed and make excellent cut flowers. For best results grow in full sun in moist but well-drained soil, and lift the tubers in November to overwinter for the following year. ... Learn More

  15. DAHLIA CAMPANULATA

    Pendulous bell-shaped, golden-eyed, pale lavender flowers, up to 6 inches or 15 cm. across, hang from the enormous blooming panicle that can reach one metre across. Surely the rarest and grandest of all Dahlias, and seldom seen in gardens, it was only recently discovered in cool cloud forest at high elevations, (around 2000 m.) in Oaxaca, Mexico, where it is accustomed to cool days and not-too-cold nights. This gorgeous, statuesque, deciduous perennial tree dahlia, with towering height and bamboo-like stems can grow up to 3 m tall. It is late-flowering, from September onwards (in the northern hemisphere), bud formation being initiated by shorter day length. It will prefer a sheltered spot in cold areas, or alternatively it can make the most impressive greenhouse or conservatory plant you will ever see! After blooming, the plant may be cut down all the way to the ground as the stems die away. (Image courtesy of John McKenna) ... Learn More
