With exceptionally beautiful bronze foliage, and large, single flowers in a flamboyant mix of rich colours - deep reds, orange, pinks and gold, this makes a wonderful cut flower. It can even be very easily grown as a half-hardy annual and will flower the first year from seed, and is related to the famous and expensive "Bishop Series. Alternatively, you can save the tubers, when formed, for ensuing years, simply leaving them in the ground in milder areas. Absolutely spectacular in bedding and containers. ... Learn More

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

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

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

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
