It's all yellow today at Langford, as I made my way around the Phase 1 grassland, which seems to be a sea of colour!
Birds-foot trefoil, or Lotus corniculatus to be scientific, is now in full flower. The flower buds when in development are red in colour, but when in full flower, it is a bright canary yellow colour. It is the foodplant of the common blue butterfly, Polyommatus icarus - which is in flight now (on warm days!).
Related to birds-foot trefoil is hop trefoil, or Trifolium campestre. The flowers are similar in shape to the previous species, but are tiny and are borne in spherical shaped clusters. A common species throughout much of the UK on dry grasslands, roadsides and other grassy areas.
The very common and widespread meadow buttercup, Ranunculus acris is now in full flower. Unlike it's close relative, the creeping buttercup, or Ranunculus repens, it does not send out runners.
The aptly named pineappleweed, or Matricaria discoidea, does indeed smell of pineapples when crushed. It is a very common plant found on open ground throughout much of the UK.
And finally, can anyone tell me what this soon-to-be yellow flower is....answer next week.
