Categories: , SKU: BONtub Tag:


This vigorous variety, introduced in 1982, is one of the earliest Giant Dahlias to flower. When grown 2 up for showing flowers could easily reach 35 cm across! It is still a popular variety for showing, regularly featuring in championship winning exhibits. The well-formed blooms of bronze and yellow blends have petals which evenly overlap and have a slightly reflexing habit giving the individual blooms good depth. Good stems and a long footstall means that a good stem for cutting can be achieved by removing 2-3 pairs of buds below the terminal bud though removing more will result in bigger blooms.

Dahlia Pot Tubers  

The tubers we offer are dahlias which have been grown for a full season in the confines of a 4” or 5” pot, so that a small compact tuber is produced. They are ideal material for the exhibitor with a heated greenhouse or propagator to enable their own propagation. Tubers are available from DECEMBER to FEBRUARY and are packed in polythene sleeves with vermiculite. We strongly advise unpacking on arrival and if necessary store tubers in a cool frost free environment until required for setting away. A minimum of 50F (10oC) is required for propagation, water sparingly until growth is evident. Should any tuber fail to have shown any signs of growth by the end of March then please contact us so we can aim to organise replacements as rooted cuttings. Please note Pot Tuber numbers are limited so order early to avoid disappointment.

Also available as mini plants or garden ready
