Dahlia
Name: Pronounced DAY-lee-a
Description: The native forms are quite simple
and daisy-like, but breeding has resulted in some wonderful flower forms, including
complete globes full of petals (pompoms), spiky and spidery forms (cactuses),
and ones with curled tubes of petals like sea anemones. Origin:
Dahlias are native to Mexico and South America, and have the vibrant intense colours
associated with that part of the world. Availability:
Main season June - October. Varieties:
Dahlias and chrysanthemums with many-petalled flowers are closely related and
often hard to tell apart. Dahlias have hollow stems, with raised joints where
the leaves attach. Their leaves are smooth, usually with points, whereas chrysanthemum
leaves are soft, with rounded edges. Care Tips: Dahlias
are thirsty flowers, so check water levels regularly and remove leaves to reduce
transpiration. Trivia: Facts:
The National Collection of dahlias is held at Varfell Farm, Long Rock, Penzance,
Cornwall. For a few days each September the collection is open to the public,
when over 10,000 dahlias can be seen in full flower, against the stunning backdrop
of St. Michael's Mount. For more information please visit their website at www.wgltd.co.uk
History: Dahlias were first recorded by Westerners
in 1615, when they were called by their Mexican name, acoctli. They disappeared
from record until 1787 when a botanical expedition 'rediscovered' them, and sent
seeds back to their headquarters in Europe. Their existence was kept secret for
another ten years however.
