  1. 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

    DAHLIA CAMPANULATA

    Pendulous bell-shaped, golden-eyed, pale lavender flowers, up to 6 inches or 20 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. ... Learn More

  3. DAHLIA COCCINEA WILD FORM

    Numerous brightest orange-red flowers open in late summer on plants which have quite finely dissected, bright green foliage. Originating from the mountainous regions of Mexico, they can grow extrely large in the right conditions, especially in good soil and with shelter of a wall. Although often reputed to be tender, the plants that produced these seeds have lived happily outside here with no protection for more than 15 years. ... Learn More

    DAHLIA IMPERIALIS

    Reputedly the largest of all dahlias, this Mexican giant, in perfect sheltered conditions, can grow up to 5-8m tall, but not quite that tall in the UK! Enormous, dense clusters of large, golden-centred, pinkish-mauve flowers open on the strong, bamboo-like stems. These are thick and become woody at the base, and along with the dark green, divided, velvety leaves, often have a purplish tinge. Budding and flowering, usually in September, is initiated by a long warm autumn and days getting shorter. This magnificent beast is an unbeatable architectural plant for a warm exotic border or a large container in a greenhouse or tall conservatory. ... Learn More

    DAHLIA IMPERIALIS 'CAERULEA'

    As beautiful as it is rare, this is the not-often-seen pale blue form of this fabulous native Mexican tree dahlia. An impressive species, it reaches heights in excess of 8' (2.5m) in a single season, and to ensure successful flowering it needs to be grown in rich, well-drained soil, in a situation protected from frost. The enormous 6 to 8 inch flower blooms seldom appear before September or October, but even long before then it makes an absolutely stunning foliage plant with finely cut leaves in abundance covering the unusual bamboo-like stems. If you live in a cold place, and would love a treat...try a large pot in a tall greenhouse or conservatory! Seldom seen or offered. ... Learn More

  6. DAHLIA MERCKII

    Beautiful yellow-eyed, lavender-pink starry flowers open on branching stems, above shiny divided foliage, throughout the summer. It is soundly perennial here in Devon, but a well-drained protected spot is recommended elsewhere where it will makes a deep long-lived tuber. Very few seeds collected. ... Learn More
