As seen in the rose garden at Queens Park, New Westminster. Unusual features. There's a fuchsia "tree" so our guess was older plant.
What is usually seen is the garden form 'California Glory', this appears to have the same flower shape.
Thanks, Ron. I had assumed that Fremontodendron 'California Glory' was merely a selection of F. californicum. I should have known this, not least because of UBC's connection with Rancho Santa Ana Botanic Garden (Roy L. Taylor was director there following his tenure at UBC). According to Missouri Botanical Garden's webpage, "'California Glory' was introduced by the Rancho Santa Ana Botanic Garden in 1962. It is a hybrid cross between F. californicum (native to rocky soils and slopes in sunny mountain areas of California, Baja California and central Arizona) and F. mexicanum (native only to San Diego County and Baja California and is included on the CPC endangered list). Prior to 1893, Fremontodendron was known as Fremontia (reportedly discovered by explorer John C. Freemont in 1846)."
'California Glory' has a glorious flower, big and wavy etc. And perhaps a more glorious flowering: mine was packed this year. Christianson's Nursery near Mount Vernon, WA also had 'Ken Taylor' recently. The one gallon plant seen there had the more prim flower shape, presumably in the manner of at least one of the wild species.
