Hydrangea macrophylla Lacecap has flat, lacy flower heads: a centre of tiny blue flowers ringed by larger open petals in shades of mauve, pink and blue, from summer into autumn.

Colour depends on your soil: acidic soil or ericaceous compost gives bluer flowers, while alkaline soil brings out pinks. Lovely in borders, large pots and partial shade, and popular with pollinators.

Supplied in a 4L pot. Free collection from Ashton Hayes.
