    You can find lots of good photos by Douglas Justice in his April 2021 in the Garden - UBC Botanical Garden blog. I posted the first ones he mentioned, Rhododendron praevernum and R. barbatum, last month at Mid-March, 2021 | UBC Botanical Garden Forums, so I got to do ones that were new to me today.

    I think this is R. pachytrichum, next to a very tall R. barbatum. This is not supposed to be new to me, but I have not learned the name at all yet.

    R. lutescens at Kingdon Ward Way (this isn't new to me - I recognized one all by myself in Stanley Park, having learned it here).

    This group is on Staunton north of Upper Asian Way. I think the mauvy-coloured flowers are the same species.

    Rhododendron principis must have the softest abaxial (leaf underside) surface of any plant. It didn't seem to rub off, so I wondered if that was indumentum, but it seems to be, according to Rhododendron principis - Trees and Shrubs Online, which says "lower surface covered with a white to fawn two-layered indumentum, the upper layer spongy, lanate-tomentose, composed of ramiform hairs, the lower compacted". I probably am not successful here in showing you how wonderful this feels. The flowers are a little past their prime, but that was irrelevant.

    Time out for my favourite rhododendron of the day: R. parmulatum 'Ocelot'. I have seen this before, posted one photo and went on about how it was such an incredible pale yellow that I could not capture in my photo. I didn't think of that at all today, and I have no idea if the colour here is representing what I saw. I only noticed the great purple markings on the outside of the flowers. That photo is at March 13, 2015 - Five Rhododendrons | UBC Botanical Garden Forums, and if you go to look, check the next posting of Daniel Mosquin's photo of R. barbatum, in which he totally captures the vibrance of the colour in those flowers.

    Back to the blog, for my second favourite of the day - Rhododendron leucaspis, in the Asian section of the alpine garden. This has today's best all over hairs.

    "This has today's best all over hairs."

    I guess the name Rhododendron hirsutum must already have been taken.

    I know. I always feel bad when some plant doesn't get the best name because some other less worth plant has taken it.

    Here are two rhododendrons that were not in the blog.

    Rhododendron floribundum. I think I just saw this in Stanley Park yesterday. That's a second one I've learned from my visit.

    Rhododendron calophytum

    First cane across Rhododendron calophytum at the Exbury Gardens in Hampshire many years ago. A very beautiful plant, but very ungainly IMO. Looks like it is of the same habit in Stanley Park Wendy.
    Brought back happy memories of family visits, so thankyou.
