Hydrangea Sweet Marshmallow 5 litre

Full mophead flowers with a bright pop of blue, and lots of them, from June to October. Sweet Marshmallow is part of the Flair and Flavours range from Proven Winners: compact, hardy and low maintenance. Keep it blue with ericaceous compost in a pot, since alkaline soil turns it pink.

Good to know: 1 x 1m. Full sun, well-drained soil. Fully hardy. Cut back by a third in spring. Toxic if eaten and may cause a skin allergy, so wear gloves.
