Douglas Justice's August 2019 in the Garden | UBC Botanical Garden blog has lots of good photos this month - I recommend following the link and having a look. I had fun following it around the garden. I'll start where the blog ends - with Campsis x tagliabuana 'Madame Galen', on the Arbour near the food garden. The flowers here are past their prime now - you need to hurry on out to the garden if you want to see them. As Douglas mentions, the Campsis radicans in the Carolinian Garden are just getting going, in every meaning of the phrase. They are in the shade, or on the ground, so are not bloomers yet, but they are also doing a good job of spreading. All but the last photo are in the Marshall Grove, which is near the SW corner, extending three or four meters square; the first two are on Quercus rubra, then on Liriodendron tulipifera. You may have seen the recent thread on these forums: Trumpet Vine Death, in which the poster is complaining about new shoots emerging in many different areas of her garden on Vancouver Island. It's easy to see how this could be the case here, as it's doing such a good job of spreading even in the deep shade. Or maybe all these were planted?? I see that this plant is not officially considered invasive in the Pacific Northwest; the poster in that other thread would probably have a lot to say about that.
