Mahonia
Mahonia xmedia Winter Sun' and 'Charity' both huge mahonia which provide a really dramatic display. The blazing colour is fabulous now. The evergreen leaves are leathery and spiky like holly. Mahonias are really good in shade and growing in some quiet difficult positions where many plants would struggle.
Corylopsis pauciflora buttercup witch hazel
This is just coming out and is in stock on the Nurseries looking good bed for the early spring season. It under plants successfully with epimedium and tiarella. I also think it looks very pretty to see the golden little flowers growing through the red dog wood, Cornus sibirica. It does lean towards lime free soil.
Hamamelis Witch Hazel
Lonicera fragrantissima
Sweetly scented and often unobserved most of the year, hidden in a hedge or a border. This honeysuckle makes a big bushey green shrub that must be pruned after flowering or it will become massive but the sweet scented flower is a joy in January. Its very hardy growing in my NE aspect and exposed to the open fields.
Camellia
Camellia
This is a beautiful show stopper bloom the appears from January and February and into early spring. Large rose like flowers in a multitude of colours. The foliage is evergreen and it is often grow as a climber against a wall or maintained as a large shrub. Never grow on an east wall as the early morning sun may scorch and burn off emerging buds. Its leaning towards disliking lime so pot in ericaceous soil.
Camellia sasangua
This is the evergreen early winter flowering camellia that can flower from November that you may not have seen.
Viburnum × bodnantense 'Charles Lemont' (below) or 'Dawn'
Viburnum tinus 'Lisa Rose'
I love this new variety. It is attributed as having greater resistance to viburnum beetle and a long flowering period. I've planted it in winter containers and it looks brilliant. If you get viburnum beetle you need to remove the lower foliage to prevent the beetle climbing up the stem and nibbling leaves. Your plant will easily recover if you do this.
Sarcococca
Prunus Subhirtella Autumnalis Winter flowering cherry tree
A cherry tree with winter blossom always needs a mention and was in my top 10 choices for Winter Colour last month.
Hybrid Winter Gold Collection Hellebores, Ice N' Roses.
Hybrid Winter Gold Collection Hellebores, Ice N' Roses.
These are varieties that are crossed with the Christmas rose helleborus 'Niger' They appear to have more vigour, bolder flower a longer flowering period and are more robust, flowering over the foliage and not in secret! They are much more substantial and establish well. The stronger coloured orientals crosses or Lenten roses will flower more towards late February march allowing you to plant a secession of one of the best early bloomers.
Violas and primroses deserve a quick mention. Excellent winter bedding plants for a burst of colour. Easy plants to mix into a border or brighten up a pot.
