I wanted to re-attempt this photograph this year, but if you visit the forums link above, you’ll see why I couldn’t. This year, the Genista pilosa ‘Vancouver Gold’ (‘Vancouver Gold’ woadwaxen) that formed the yellow background in my photo was not blooming with the same density of flowers at the time that the Henderson’s triteleia was at its peak. It’s a small example of how springtime weather affects phenology or the sequence of growth and development events in the life of plants. It also makes it easy enough to imagine the troubles caused by seasonal asynchrony driven by climate change.
Triteleia is a genus confined to western North America, ranging from British Columbia south to northwestern México. Henderson’s triteleia or Henderson’s tripletlily is a species of southwestern Oregon and northwestern California. The plants in today’s photographs have been cultivated in UBC’s Alpine Garden since 2006.
