Of course I'm in Scotland and this is Benmore Botanic Garden, a wee way west of Glasgow. There are 11,000 plants from all over the world - particulary Asia and the Americas - including an impressive collection of more than 300 species of Rhododendron. (For no other reason than I like this picture, I'm showing a close of up a Magnolia, of which there are a few...)
The giant redwood entry avenue is an impressive start but the local topography is the star. Well that and the rainfall. This botanic gardens gets more than three times the rainfall in Edinburgh, where a pretty impressive botanic garden is situated (certainly one of the top half dozen in the world). An average of 2,500 mm (100 inches in UK money) rain falls in each year, helping maintain these luscious moss cushions - consisting of a Polytrichium-like moss over the top of Sphagnum.
And finally, what is it about the Himalayan Blue Poppy (Meconopsis betonicifolia). Every botanic garden worth its name has at least a half dozen. Benmore did...
And just to whet the appetite of all phycologists in my readership (yes you) and those who look down, rather than up at the trees, a river looking like it should be full of algae but wasn't.
[*Late addition: it seems my geography has let me down. In my rush to claim the northernmost (top) UK botanic garden title for Benmore Botanic Garden, I just used my road map and pointed it vaguely northward. My internet research indicates that while Benmore is 56 degrees and 1 minute north, Edinburgh just pips it at 55 degrees and 57 minutes. My apologies to everyone in Edinburgh for this slight. What's four minutes between friends?]
