About
Aster alpinus 'Goliath' is a perennial that typically reaches heights of up to 40 cm during its flowering period. This low-growing plant forms dense clumps and features a layer of slightly coarse, hairy leaves shaped like narrow lance or spoon forms, all in a vibrant green hue. From early summer until late autumn, it produces solitary, daisy-like blooms in a purple-blue shade, each adorned with a yellow center.
