Dahlias for Sale

Dahlia Tubers in Premium Sizes

Dahlias are wonderfully colourful and prolific tuberous plants that fill the late summer garden with a glorious range of flowers that continue until the first frosts. In the garden, you can have a display ranging in size from little pom-poms to huge "dinner-plates up to 25 cms (10") in diameter and in a range of shades from white and cream through yellows and oranges to pinks, reds, lilacs and purples: even near-black. About the only colour you won't find is a good blue. In the house, dahlias are a superb cut flower and the plants produce so many blooms that you can cut daily without impacting the show outdoors.

Dahlias are tender, so they should not be planted out until the frosts are over, around late May. To get a head start they can be potted up earlier and grown on in a light, frost-free place until it is a little warmer.
They are available as tubers (for potting up), as rooted cuttings for planting out in May, or as larger pot-grown plants for instant impact from late June onwards. Give them plenty of organic matter in well-drained soil and full sun.

Dahlia Classification

Involute petals face inwards, to the centre of the flower, and revolute flowers are outward facing. 

Single Flowered: One outer ring of florets, which may or may not overlap, and make up a disc in the middle.
Anemone Flowered: One or more outer rings of ray florets (usually flattened) around a mass of tubular florets, with no visible disc in the middle.
Collarette: One outer ring of ray florets (usually flattened) that overlap, and an inner ring, or collar, of small florets, with a visible disc in the middle.
Waterlily: Wide but shallow, fully double, open blooms with wide ray florets. The depth of the bloom is not more than one third of its diameter.
Decorative: Fully double, with no visible disc in the middle. The ray florets are normally wide, and either flat or twisted, and typically have a blunt end.
Ball: Fully double, and form either a near-perfect or flattened ball. The ray florets are rounded at the tips.
Pompon/Pompom: Fully double & spherical, with florets largely involute along their length (longitudinal axis).
Cactus: Fully double, typically with pointy ray florets, most of which are narrow and revolute for over 65% of their length (longitudinal axis) and either straight or involute for the rest.
Semi-Cactus: Fully double, typically with pointy ray florets that are revolute for between 25% and 65% of their length, wide at the base, and either straight or involute for the rest.
Star (formerly Single Orchid): One outer ring of florets around the disc. All the ray florets are either involute or revolute.
Double Orchid: Fully double, no visible disc, with triangular centres. The ray florets are narrow, and all of them are either involute or revolute.
Paeony: Several outer rings of ray florets around a central disc. The florets are flat or slightly involute at the base, and the rest is flat slightly revolute.
