This week’s challenge for #Wildflowerhour was to find as many of the Brassica family in flower as possible. I’m rather pleased with the number I’ve found, though I’m not 100% sure of my plant IDs, so if you think I’ve got any wrong, please do comment below. And I’ll edit this post if I need to, to reflect the corrected information.
American winter-cress (Barbarea verna): this is the identification I’m least confident about, as it’s a plant I’ve not seen before, and only a couple of flowers were actually open, but the leaf shape seems to fit.
Common whitlowgrass (Erophila verna): his plant is very common in my area but it’s one I often overlook because of its small size. It’s a pretty wee thing though.
Cuckooflower (Cardamine pratensis): found earlier this week but this is a new photograph as I’ve since revisited the site. It’s certainly earlier in this particular location than in the other places I’ve usually found this plant, which, I suspect, is due to aggressive cutting by the local council in those other locations (Cardiff Bay and Hamadryad Park).
Hoary mustard (Hirschfeldia incana): Argh, so many plants that look similar! The only reason I’m reasonably confident about this one is that I’ve posted a photo of it previously on Twitter and an expert named it for me.
Sea radish (Raphanus raphanistrum ssp maritimus): This is another plant previously identified by one of the Twitterati and, though this was a slightly different location, it was also on the shores of Cardiff Bay so hopefully I’ve got this one right.
Wavy bitter-cress (Cardmine flexuosa): The bitter-cresses always confuse me but, though it’s hard to see them, these flowers have six stamens, which is a key ID point to confirm this as Wavy rather than Hairy bitter-cress.
Shepherd’s-purse (Bursa pastoralis): The purse-shaped seedpods of this lovely little plant make it unmistakable, thank goodness.
