Flowers for Christmas?
Of course, there’s no absolute assurance that winter plants will come up trumps for Christmas. But to encourage the best show possible, plant in the right place. For instance, the Algerian iris (I. unguicularis) enjoys poor soil at the bottom of a sun-baked wall, and dogwoods (such as Cornus alba ‘Sibirica’) must be grown in full sun to ensure their stems blaze bright scarlet.
If buying containerised plants now to put in the ground for Christmas, make sure they look healthy and show no signs of being pot-bound.
