This double-flowered variety of Kerria (Japonica Pleniflora) is also known as Bachelor's Buttons, Jew's Mallow and Japanese Rose. A really pretty shrub to have around the garden at this time of year. I really like the combination of the 'custard powder' yellow of the blooms against the lime green of the leaves.
It will grow just about anywhere and if left to its own devices can reach up to 6ft tall. It will also spread by suckers which grow from its creeping underground root system. A plant which is best kept in check by pruning out all the old flowering stems.
William Kerr a protégé of Sir Joseph Banks, the famous 18th-century naturalist and plant collector, bought this particular variety back from China in 1804. By 1838 it was so common it was to be found in the gardens of labourers cottages!
