‘Walls may not seem the most hospitable of environments, but the plants that survive there can be surprising’. This week’s challenge is all about flowering wall plants, so we’ve focused on the few walls we actually have on site.🌼🧱
The former hospital buildings in the Countryside Centre don’t offer much in the way of flowering species, but the old brick walls 🧱 and lime mortar support wall‑rue and maidenhair spleenwort sitting tight in the joints 🌿. Lime mortar stays slightly porous and holds a bit of moisture, which is why these masonry specialists persist here.
As these aren’t part of the flowering brief, we headed over to Rising Sun Farm and the sandstone wall around the livery yard. This wall has been repointed in places, and modern cement pointing changes the wall habitat - harder, less porous, and no longer offering the same conditions that support true wall plants. Even so, several areas along the wall have cracks where the repointing has dislodged, leaving gaps - some small, some quite large - that catch blown soil and run‑off 🪨. These are the spots that support the opportunists we spotted this afternoon: common daisy , smooth sow‑thistle , field forget‑me‑not , common nettle , herb‑Robert finished flowering and already set seed , and one of the small willowherbs 🌼🌱🌸.
True wall plants such as wall‑rue, maidenhair spleenwort and species such as ivy-leaved toadflax anchor directly into the mortar rather than relying on blown soil - a clear contrast with the opportunists using the dislodged gaps on the farm wall.
Two walls, two very different conditions: lime mortar still holding its specialist ferns 🌿, and repointed sandstone offering gaps 🪨 for opportunistic plants 🌱 that simply make use of whatever spaces are left.
