It’s been a while since I have posted up on my blog, I should hopefully be posting more regularly again now that spring is around the corner. It feels like ages ago now but HAPPY NEW YEAR. I can’t believe that January is almost over already and spring is around the corner. That pasted super quick. My colleagues often tell me, the older you get the faster time flies. I hope it doesn’t go too quick this year as it promises to be a good one. It shouldn’t really be a surprise to you that I don’t like winter all that much like many, many people. December is a good month though. You have Christmas and New Year to look forward to and Christmas planning takes a good chunk of my time up. Though after the new year, January and February begin to drag and go on and on until I am so fed up. Then it’s suddenly spring and the world bursts into life. 

However, since it is winter, I have decided to do a post about winter colour in the garden. Before I started studying horticulture I was like most people. Winter was all about the cold, the wet and the grey but as I have been working in gardens for 4 winters now, I have started to see the beauty in the cold and the wet and the grey. Simply because it isn’t so dreary if you open your eyes. So many plants are flowering or have colourful bark that draws you in. When trees drop their leaves, you can see them in their full architectural glory and it’s as exciting as summer. If any of you reading this are gardeners, horticulturists or in a land-based industry then I know I am preaching to the choir. There are so many plants looking great in the garden now whether its flowers, bark, leaves or shape. Below is a list of a few which if you don’t know then you should definitely become acquainted with: 

·      Eranthis hyemalis or Winter Aconite – This plant has yellow low-growing flowers which are produced from a very small tuber between January and February. Worth taking a look at if you are looking for a plant to naturalise into woodland. I have often seen this plant used in a scheme with dwarf daffodils and snowdrops naturalised in colourful winter displays. 

·      Helleborus hybrids or Christmas Roses and Lenton Roses – This flowering perennial produces flowers throughout winter and into early spring in varying shades of colours from white and pale yellows all the way through to dark purples and pinks. A wide range or cultivars are available to suit everyone’s tastes.

·      Hesperantha coccinea or Crimson flag lily – Hesperantha is a great addition to any garden with its crimson flowers that appear from autumn until early winter. This plant flowers a little earlier than the others on this list but it is such as good plant that I couldn’t miss it out. In especially mild winters or in warmer parts of Britain such as South West England the flag lily may continue to flower sporadically through January and February. 

·      Skimmia japonica or Japanese Skimmia – It’s not the flowers that made this plant make the list, the berries of Skimmia come in all sizes and colours. Skimmia are an evergreen bush that produce berries from autumn that hold all through the Winter. Be careful though, there are separate male and female plants of Skimmia so in order for your female plants to produce berries there must be a male plant nearby. 

·      Daphne bholua or Nepalese paper plant – This Daphne produces pink flowers from early winter through to the end but it isn’t the colour that I love but the smell. Daphne’s flowers produce a strong sweet scent which is most noticeable on sunny cold days with a slight breeze. It hits you like explosion of scent that can sometimes be overwhelming but I often find myself searching around for the source to stick my nose in for a good whiff. 

·      Camellia cultivars or, err well…, Camellias – I am of the strong opinion that there is a camellia for everyone. This genus of plants is wide and varied, many flowering from winter into late spring with shades from white through to pink, with or without scent. My personal favourite at the moment is Camellia sasanqua ‘Pinafore Pink’, this may change as the season progresses though. Camellias are great plants in pots or in borders. I hasten to add however, that Camellias are acid loving plants so prefer ericaceous soil (fancy name for soil with a pH below 7). Pots are a fantastic way to grow the plants you love without having to lower the pH of your main borders. This way you can grow a large range of plants with less effort.

·      Erica carnea or Winter flowering heathers – Continuing on with the theme of ericaceous plants. The winter flowering heathers are usually in the Erica genus although there are also other genera of heathers which flower throughout summer such as Calluna and Daboecia. Heathers are low growing evergreen shrubs which are often used in winter garden schemes with conifers and snowdrops. Flower colour spans through from white to pink and on to vibrant purples. 

·      Galanthus species and cultivars or Snowdrops – I could write a whole separate post about snowdrops and in fact, I probably will. These tiny bulbs are beloved throughout the world and flower from autumn through to early spring. There are so many cultivars of snowdrops which are variants on each other that I couldn’t even begin to count them all. I do know a few though ‘Grumpy’, ‘Wendy’s Gold’ and reginae-olgae are some great choices for anyone looking for unusual snowdrops.

·      Rubus thibetanus or Ghost Bramble – This plant is vicious with its barbed white stems and can sometimes be invasive. On the other hand, if you have a large amount of space to fill which is low maintenance then this is the plant for you. All you need to do it cut it down to the ground every year in the early spring or every second year whatever works best for you. This plant is deciduous so loses its leaves in winter but the stem colour on snowy days is so worth being a human pin cushion when pruning. 

·      Ophiopogon planiscapus ‘Nigrescens’ or Black Grass – Black grass is actually a grass at all but in the Asparagaceae family meaning it is related to the Asparagus that appears on our plates in the summer. You can’t eat this one though as its dark purple berries produced after flowering will give you a stomach upset. This Ophiopogon is an evergreen perennial plant, the leaves on this cultivar are a dark purple almost black. A great addition to any shady garden. 

I have decided that in this next part I would like to talk about 3 different plants which all have their own unique qualities that make them an excellent choice for any winter garden. Hopefully I will keep on track and not waffle on too much but I am going to share with you why I love these plants so much. 

Cyclamen coum

Cyclamen coum growing in a slate wall.

Genus: Cyclamen coum

Family: Primulaceae

Common name: Eastern Cyclamen

Growing conditions and why to grow it: Cyclamen coum is an excellent choice for a low growing ground cover plant as it spreads rapidly in the right conditions. I have often found the leaves, although all a similar shape, can vary in size and can sometimes have a silver lining across the top surface. The flowers are pink with a purple base where it attaches to the flower stem and appear from early winter into spring. Cyclamen coum prefers a sheltered position in partial shade. It grows best in a fertile and well-drained soil. What’s better is that this plant will come back year after year and hopefully spread through a border.

Interesting facts: The name Cyclamen comes from the Greek Kyklaminos which refers to a circle. This alludes to the coiling stem on the seed vessel. Coum refers to the island Kos off the coast of Turkey which is part of the plant’s native range. 

Cornus ‘Anny’s Winter Orange’

Genus: Cornus

Family: Cornaceae

Common name: Dogwood

Growing conditions and why to grow it: There are so many impressive dogwoods it was hard to choose but this is my personal favourite. Although, ‘Midwinter Fire’ and ‘Kesselringii’ are up there with the best too. ‘Anny’s Winter Orange’ has orange through to red stems that draw your eye like fire in the winter months. In the picture above, it has been paired with Skimmia japonica ‘Scarlet Dwarf’ so that the reds pick each other up. This Cornus doesn’t really mind where it is put just preferring sun or partial shade. It really is an all-rounder.

Interesting facts: This dogwood can be cut down each spring before the leaves appear to replenish the winter stem colour each season but can also be left to grown taller and cut down every 3-4 years. Like many plants, this plant can be propagated by hardwood cuttings. Cuttings taken in the winter when the stem is bare. 

Hamamelis x intermedia ‘Jelena’

 

Hamamelis cultivar, probably 'Jelena'

Genus: Hamamelis

Family: Hamamelidaceae

Common name: Witch Hazel

Growing conditions and why to grow it: This plant is a little pickier than the other two liking well-drained to moist soil, in full sun or partial shade in acidic to neutral soil. Easy requirements to fill if you work down in Devon like I do. This is a medium to large deciduous shrub which produces hundreds of subtly scented orangey to red flowers from January to February.

Interesting facts: Hamamelis virginiana is a relative of my chosen plant. This witch hazel has bark and leaves which are often used in the production of cosmetics. It is sold as a treatment for acne, skin irritation, inflammation, an anti-bacterial facial and protection against skin damage. 

Here are a few book choices which have helped me in the past:

I hope you have enjoyed reading this post, I certainly had fun writing it. Until next time!

Some extras which didn’t make the list above:

·       Some Hydrangea flower heads stay on the shrubs over winter.

·       Many flowering perennial plants which flower in summer have seed heads which will last throughout winter until cut down.

·       Miscanthus among many other grasses turn varying shades of brown over the winter providing architectural interest.

·       Conifers are old but gold when it comes to winter schemes – yellow or blue cultivars give a pop of colour on dreary days.

·       Winter bulbs such as crocus, Chionodoxa and daffodils work well together to plant the under story of borders.

·       Berries are important for the ecosystem and many plants produce spectacular versions of their own which hold their own against some of the showier flowers such as hollies, sacred bamboo and rowan.
