Description
If you’re a lover of all that is unusual, Dahlia 'Honka Black', (also known as Dahlia 'Verrone’s Obsidian') are going to be on your wish list. Are they black? Well, not quite, but they’re such a deep red that they’re almost black! But Dahlia 'Honka Black's charm extends beyond the colour of its petals. The unusual flower form is a definite attraction. It’s as if your garden were suddenly adorned with a constellation of black stars with brightly contrasting yellow centres.
With a maximum height of only 60-70 cm, Dahlia 'Honka Black' is easy to find space for in almost any sunny garden, and it lends itself well to being grown in containers too. Contrast it with white flowering plants or let your black dahlias have a bed all to themselves.
Gracy's gardening tip:
"Remember – it’s easy to save your dahlia tubers for replanting next year, and the year after, and the year after that."
