Cosmic Comet Sedum Sunsparkler is a hardy succulent in the Crassulaceae family, bred from sedum species native to rocky, well-drained habitats across the Northern Hemisphere. It belongs to the Sunsparkler series, selected for exceptional cold hardiness, compact habit, and ornamental color that performs in Zone 4 through Zone 9.
It forms tight, low-growing clumps of small, fleshy leaves in blue-green with rosy-pink edging that deepens in cooler temperatures and bright sun. The foliage is smooth, plump, and tightly packed into a neat mounding habit that stays tidy without pruning.
Sedum 'Cosmic Comet' produces cheerful pink flower clusters on upright stems in late summer to early autumn, drawing bees and butterflies to the garden. A cooler night temperature drop in late summer can encourage more abundant flowering. The blooms naturally attract pollinators and produce pollen, which is worth noting for allergy-sensitive households.
It handles dry heated indoor air well. Move it outside in summer. You can leave it up to ten days without water. It does well on a sunny balcony, in a rock garden, or along a dry border where wind, rain, and fluctuating autumn temperatures occur. Sedum 'Cosmic Comet' is pet friendly, non-toxic to cats and dogs. The leaves shift color across the seasons from blue-green to deeper burgundy tones.
