It's celandine time. The lesser celandine (ranunculus ficaria) They make a stunning yellow carpet massed on banks on countrywalks. And then they disappear until next year.
If you get them in your garden (unless it's one of the cultivars like "Brazen Hussy")they are very hard to get rid off. They propagate primarily by small tubers and bulblets and spread quickly. But in the countryside at this time of year when the sun shines they are a joy.
