The Flora of the Patagonia Steppe

with Kiamara Ludwig
Monday, July 17, 2023 – 6:30 p.m. on Zoom or by phone
(if you are not a member but would like to be you can join

Kiamara is a skilled grower and gardener with experience in many specialized plant groups: geophytes, ferns, alpines and alpine-like plants, succulents, and bryophytes. Ms. Ludwig was one of the primary instigators in starting the Bryophyte Chapter of the California Native Plant Society (CNPS). She, and a small cadre of dedicated grower-gardeners, have recently rejuvenated the Western Chapter of NARGS. In 2020, she completed her four-year term as an Interpretive Student Aide at the Regional Parks Botanic Garden in the Berkeley Hills, where she continues with her main interest in plant propagation. While a long-time member of NARGS, she has until recently focused primarily on propagating plants for the rock garden group at the San Francisco Botanical Garden and for private clients allowing her to install rock gardens.

Supporting Each Other

Plants do not recognize race, economic condition, or social class. Plants can take root in any spot where they can find sufficient sunlight and moisture. Appreciating and nurturing plants can reduce stress, provide food, and promote community.

Nurturing plants can be for everyone, everywhere. Spending time around plants—gardening, spending time in a park, hiking through trees, or playing in a meadow—is good for mental health, promoting relaxation and relief from stress and worries. There are physical benefits to sunlight, fresh air, soothing scents. 

Whether you have a full garden, some house plants, or a few herbs on your windowsill, we encourage you to take time to appreciate the colors, textures and, and to share your interest with others. Share photos and web links, offer horticultural help and advice, talk to young people about gardening, growing food, and the role plants play in our world. We can all help shape the future for good.
