A kind thank you to sagellyn@Flickr for providing today’s photograph (via the BPotD Flickr Group Pool | original image). The photograph was taken at a Vancouver nursery, Southlands. Thank you, sagellyn – always happy to feature something South American in origin.
Native to south central South America (Bolivia, Uruguay, Paraguay and Argentina), Echinopsis oxygona is a member of a genus of cacti collectively known by the common names of Easter lily cacti or sea-urchin cacti. I prefer the latter name myself, especially after viewing the third photograph in this series on Echinopsis oxygona.
I often write about plant names, it being a particular interest of mine. There are few groups of plants more confusing to those who would attempt to name and classify them than the cacti. Exhibit A: a listing of accepted names and synonyms in the genus Echinopsis – roughly one hundred and thirty species are recognized, but the page contains over five hundred and thirty names, more than four published names (on average) for each species!
Botany / horticulture resource link: Take the time to learn about the diversity of form and colour in both species and cultivated maples through these two extraordinary photo galleries: the maple photo gallery and the Acer palmatum cultivars photo gallery. The garden hosts these on its discussion forums, but the resource was built by people from around the world (and a big thank you to all of you!).
