The hotel I’m staying at apparently prevents me from uploading images for BPotD because of some sort of file size restriction, so I’ll have to find another venue for the rest of the week. In the meantime, I did have this entry I started to write last year until a question came up that has so far proven unanswerable, so I’ll share it instead.
The cultivar name ‘White Icicle’ for this flowering currant was published in 1986 in HortScience 21(3):362, by Dr. Gerald Straley of UBC Botanical Garden (deceased 1997). Commercially introduced in 1988 as part of UBC Botanical Garden’s plant introduction program of the time, it was a variant that had originally been selected in 1973 from Vancouver Island. Compared to other white-flowered cultivars, it is generally considered more desirable as it has pure-white flowers and it is a more vigorous plant overall. While visiting some public gardens in Washington and Oregon this past week, I’ve spotted it planted prominently near the entrances. It is, at least regionally, indeed deserving of being one of the Great Plant Picks.
The question I’ve yet to answer is why the Royal Horticultural Society’s Plantfinder (which we use as our initial reference for cultivar names in UBC Botanical Garden) lists the cultivar as Ribes sanguineum ‘Ubric’, and instead notes that White Icicle is a trademark (or a commercial designation with financial rights and responsibilities). I’ve searched the US, UK and Canadian trademark databases, and came up with zero results for the combination “white AND icicle”. I also don’t believe the Botanical Garden ever registered trademarks for any of its introductions, though more digging in the archives may prove me wrong.
