Appreciation: Three in the Greig Rhododendron Garden

This garden in Stanley Park borders the pitch and putt golf course. Rhododendrons are featured, but there are lots of other plants - a magnolia path, and camellia path, several ornamental cherries, many perennials, some great clumps of Gunnera. Here are just a few rhododendrons in bloom.


Nothing is labelled, but there is a document: https://vancouver.ca/files/cov/ted-and-mary-greig-garden-50-rhododendrons-of-interest.pdf, and I think for once that my plant of interest is in it. It fits the description for 'May Day' not only in its timing but the description is: " ...a curtain of red, its tabular campanulate flowers drooping in dense fan-like trusses. This plant also features attractive matte green leaves that have thick, fuzzy cinnamon brown indumentum on their undersides. 'May Day' has a rather dishevelled habit, and will grow wider than it will tall."


I have posted Rhododendron calendulaceum at UBCBG in previous years. Surely that's what this deciduous azalea is, with its flame-looking buds and hairs on everything [edited, not it's not, see below].


I don't know what this yellow flowered azalea is. I guess I just like it because it's yellow and has hairy buds.

 

I would just like to say that I looked up the spelling of the garden name on the document title that I referenced (and I look it up every time I write the name) where the last name is spelled Grieg. On the file name, however, I see that it is spelled greig. There is another document in which it is Greig, so I have changed my thread title, but all my photo names this spring from there have the incorrect spelling.

Based on Ron B's comment in Identification: - Which is the real 'May Day'? that the coloured calyx is supposed to be characteristic of 'May Day', it has to be the case that my ID of the red-flowered rhododendron in the first posting is not correct.

 

The orange azalea is a Knap Hill Hybrid and the yellow is either Rhododendron luteum or a hybrid seedling derived from it. The species is pleasingly fragrant, has been asked for at independent garden centers in the past as "that yellow honeysuckle".
