Double Black Hollyhock (Alcea rosea)
 
Double Black Hollyhock is a highly sought-after and difficult-to-find variety, valued for its near-black, fully double blooms and dramatic presence in the garden. The densely layered flowers create a rich, velvety look that stands out strongly against lighter plantings and foliage.
 
This variety produces tall, commanding flower spikes and is especially popular among collectors, cut-flower growers, and gardeners seeking uncommon color forms. True double black selections are far less common than single or dark red types, making this one a standout choice for specialty gardens.
