So walking distance from home this weekend ... Well the big news is that Grass-poly (Lythrum hyssopifolia) is back and in bloom at Skelton Lake.
Then some interesting trees near the canal in Woodlesford. First this stunning form of Sycamore (Acer pseudoplatanus f. erythrocarpum). Like its purple-leaved cousin the best forms always seem to be planted, but it does occur spontaneously as well. I'm not sure of the origin of this tree, but its looking good.
Then Green Alder (Alnus viridis), and self-sown Red Alder (Alnus rubra).
And then another alder, but which one? This is a shrubby species with small leaves that left me scratching my head. I eventually came down on the North American form of Grey Alder (Alnus incana subsp. rugosa) that looks nothing like the tree from this side of the 'pond'. It seems quite variable across its range, as indicated by the number of varieties in Sell and Murrell, but I found enough images online to provide confidence that my ID was likely to be correct (unless anyone knows better?).
