This evergreen Digitalis canariensis (Canary Island foxglove, Isoplexis canariensis) survived the winter with the protection of an unheated glasshouse. Although capable of surviving a temperature as low as -4C, it is best to avoid freezing temperatures wherever possible and to use a free draining compost.

The evergreen shrub Olearia semidentata (Chatham Island aster, swamp aster) is endemic (naturally occurring) to the Chatham Islands. The flowers made a great welcome to the Marengo Community Garden, Orkney which is sheltered from the wind by drystone walls.
