    Cypripedium parviflorum var. pubescens Z5 –
    RHS Index of Garden Plants, Mark Griffiths

    Thanks again, Beverley. I should point out that the Index of Garden Plants is wrong for this plant, since it grows natively in what would be considered a zone 2. I’m not certain whether this is due to Royal Horticultural Society being UK-based and not having a zone 2, or whether Cypripedium calceolus is less hardy than the North American C. parviflorum (is it?). In any case, when it comes to North American natives, a better “zone guide” than books authored overseas is the native distribution of the species. I’m not stating that to disparage the book, but rather just to point out the reality of distant authors canonizing bits of information that disagree with local knowledge. I’m fairly certain that one day Asian and African plant enthusiasts will say the same about what we in North America state for zones about their native plants.

    In my writing above, I neglected to mention this tidbit–please don’t dig up lady’s slippers from native sites and plant them in your garden. In some jurisdictions, they are endangered and / or protected. The only arguable justification is when an area is slated for development and the individuals will be destroyed.

    Regarding Cypripedium in Nunavut, I can only say my research has yielded “inconclusive” so far. Apparently, Cypripedium passerinum extends as far north as Churchill, Manitoba, which is about 120km south of the Manitoba / Nunavut border.

    Good point about not relying on one source of information for hardiness. It’s good to check with local gardeners, nurseries, etc. and if they’ve had success with a certain plant or if they have any recommendations regarding care. A nursery up the road in Woodland, WA occasionally sells Mexican fan palms (Washingtonia robusta)! When I enquired about hardiness, the woman replied that, with a southern exposure against a warm wall, some people here have had success.

    Neither Florida nor Nevada have any native cypripediums. That was an interesting find!
    Love the Botany Photo of the Day, and this entire website. Thanks for taking the time to host and maintain it! I will have to look for your trillium photos now! : )
