As the long, grey days of winter approach, do dormant plants leave your garden looking bleak and bare, with you feeling somewhat the same? Now is the time that many succulents shine their brightest! When other plants play dead to survive the winter, some outdoor succulents respond to the environmental stress of winter chill with a brilliant display of color — just when we need it most. For winter interest, succulents are hard to beat in any climate. Certainly, some outdoor succulents in winter go dormant and die back. Others truly die when they get too cold. This is not a list of winter hardy succulents, though many of them are hardy. Instead, this is a list of succulents that light up the garden in winter with colorful foliage.
Succulents for Winter Interest
Why Succulents Change Color in Winter
For a better understanding of how stress makes succulents more colorful, I have done a deep dive. For now, let’s agree that the cold of winter is a form of environmental stress that requires a change on the part of the plant. The two main pigments plants develop in response to environmental stress are Anthocyanin (An-tho-SY-an-in) is a blue, red or violet pigme... (blue, violet and red shades) and Carotenoid (Kair-AH-ten-oid) is a yellow, red or orange fat-... (yellow, orange and red).
As daylight shortens, and temperatures drop, succulents decrease the amount of green-pigmented chlorophyll they produce for Photosynthesis (FO-to-SIN-thuh-sis) is the process plants us... More. This makes other pigments in the plant more visible. Further, production of carotenoid and anthocyanin increase, to combat the stress of falling temperatures. Anthocyanin, in particular, acts as a plant antifreeze that protects the water inside plant tissues from turning to ice that would kill the plant. This is why so many cold-hardy succulents flush a brilliant shade of burgundy. The protective anthocyanin is shining through the leaves.
Although some succulents are hardy just to 30 °F ( -1 °C ) and others can take -30 °F ( -34 °C ) those that are colorful in winter all develop this color as the temps drop through 40 °F / -15 °C.
