Tree Mallow (Lavatera arborea) is a woody stemmed biennial which has downy fan like leaves and pink dark veined flowers. Fast growing and low maintenance. Enough always self seeds to keep some plants coming through. In flower for a long time – from early summer until around September. It is a native plant to Ireland and usually grows in coastal areas. The seeds for these were saved from my garden which is a few miles inland. It should survive anywhere in Ireland once it doesn’t get a particularly harsh frost below -5°C.
