@Edrmorris @justinehud But it’s wind borne pollen from species like ragweed that causes allergies such as hayfever, not sticky pollens collected by bees.
@Edrmorris@BioInFocus Yes, counter-intuitive, but White Spruce is dominant at the interface of taiga and tundra: so-called Picea glauca var. porsildii.
@emilyrondel@BlackOutdoors1 I remember seeing some nice Sycamores along the Humber River in or near Rowntree Mills Park (Finch Ave) some years ago. I grew up in Toronto...
@emilyrondel@BlackOutdoors1 There are true Sycamores in the Humber Valley and perhaps also the Don and possibly planted elsewhere, but ‘urban sycamores’ are mostly London Plane-tree, Platanus x hispanica.
@emilyrondel@BlackOutdoors1 What? Sycamores and maples are in different families: Platanaceae and Sapindaceae. There’s a Sycamore Maple (Acer pseudoplatanus) and Acer platanoides (=sycamore-like maple)...
@emilyrondel @BirdStudiesCan Even beloved garden plants like Buddleia davidii have in southern Ontario graduated from being essentially annuals to perennials. One only need look at lower mainland BC to see its potential as a serious weed.
@emilyrondel @BirdStudiesCan Dating myself here, but I remember when dog-strangling vines (Cynanchum spp.) were a novelty restricted to Hamilton, Toronto and Ottawa. No such thing as a benign exotic!
