A big thank you again to Eric in San Francisco (Eric in SF@Flickr) for offering today's image via the BPotD Flickr Group Pool (original image). An intriguing pattern expertly captured, Eric – thank you!
I believe this is the fourth member of the Crassulaceae to be featured on BPotD, preceded by Dudleya pulverulenta, a cultivar of Aeonium arboreum and Sedum spathulifolium. If you visit those pages, you'll note that a pattern emerges – most of the Crassulaceae are succulents.
Although this particular plant is being cultivated in the Strybing Arboretum in San Francisco, this species is actually native to southern Africa, where, like many succulents, it grows in an arid environment.
For local readers, you might like to visit Riverview in Coquitlam to attend this year's Treefest today (rain or shine!). This event celebrates the nearing-a-century-old arboretum on the grounds of the Riverview Hospital. See the web site of the Riverview Horticultural Centre Society) for more information about this heritage site that is not yet permanently protected from “development”.
