The plant lighting up this container display in a shaded walkway in Stromness, Orkney, was probably the cultivar Heuchera 'Limeberry’ (alum root). The leaves forms a mound of bright green-yellow and the plant thrives in a container with adequate nutrition and regular watering.

Plant of the Week – Heuchera (Alum Root)

Mix of Heuchera varieties

This week we are taking a look at one of my personal favourites – Heuchera! These evergreen perennials display beautiful lobed leaves in a plethora of different colours and shades throughout all of the seasons. However, while the foliage steals the limelight, we must not forget about the panicles of delicate flowers which bloom from spring to summer.
