White and very spiky the dwarf semi-cactus Dahlia 'Playa Blanca' will shiny like a small star in your garden galaxy from mid to late-summer through till the first frosts show that winter is on its way. Although the spiky white flower with its yellow centre is smaller than that of regular dahlias, this rather cheeky flower won’t rule your galaxy alone! The plant of Dahlia 'Playa Blanca' is compact, bushy and clump-forming and will produce a large number of flowers. You can help ensure that the flowering goes on as long as possible by cutting off the dead heads of the flowers when they fade.
