Plants which possess silver foliage can compliment a garden in many different ways, they provide a distinct contrast planted alongside green foliage and they can provide an all year round interest, brightening up an otherwise lacklustre area of the garden. But, it is not only a dull area that can benefit from the addition of a glaucous colour, a great attribute of silver/grey foliage is the ability to reflect sunlight and conserve water, this is enhanced by the hairy type foliage or a waxy texture of the leaves which many possess.
Many of theses plants are native to hot and dry areas and therefore drought tolerant, requiring low maintenance and will perform well in a full sun area of the garden with well drained soil.
Silver foliage adds elegance and a cool sophistication to the garden and can be found on large trees down to small ground cover shrubs and perennials. Eucalyptus, the snow gum tree, is one of the hardiest of Eucalyptus and the grey
tinged leaves on white twigs radiates an impression of silver, complimented by a grey /white smooth trunk.
Pittosporum tenuifolium ‘Silver Queen’ is a large shrub which can grow to a height of four metres. Its latin name denotes thin leaves, these having white markings on the edges, giving an affect of a silvery foliage. It is an ideal plant for coastal areas. Popular small to mid-sized shrubs are lavender and Helichrysum, both release pleasant aromas, the latter being more known as the Curry plant due to its distinct curry fragrance.
With regards to small shrubs and perennials, there are plenty available and more to choose from. Convolvulus cneorm is a small shrub native to the mediterranean and displays silk grey hairs on its evergreen foliage, hence it being more known as the Silver Bush. Santolina or Cotton lavender is ideal for ground cover and filling in gaps within the borders, the yellow pompom flowers provide a nice contrast with the silver fragrant foliage.
Another popular ground cover is the perennial Lambs Ear or
. It is also known as Silver Carpet and has oval, woolly silver leaves with fine hairs and is suitable for the front of borders, covering areas with its carpet, mat forming
characteristics. There are numerous other silver foliage plants, the following are popular;
- Senecio cineraria/Silver Dust
- Sea Holly/ Eryngiums.
- Cardoon/Cynara cardunculus
- Honeywort/Cerinthe major
- Rose Campion/Lychnis coronaria
- Brunnera macrophylla/Jack Frost
If not already in possession of silver leaf plants, then why not incorporate some into the garden, either in shade or full sun areas and if every cloud has a silver lining, then surely every garden should have some silver foliage.
They maybe all around us now and covering large areas of the garden, often regarded as a hindrance when it comes to the maintenance of a neat and tidy garden. But, alas, leaves falling to the ground is a message from nature which one should take heed of, and that message being leaf matter is the best natural and free mulch available for the gardener and grower.
Fallen leaves can be found residing in many areas, from resting on the lawn to wind blown corners of the garden and now is the time to sally forth and gather. A large pile of leaves can be transmuted into leaf mould, the decomposed matter formed when the leaves have decayed over time. The leaves can be stored in plastic bin liner bags with a few holes
pierced in the sides and bottom, once full, a sprinkling of water is advisable then storage in a shady area of the garden is essential and the following autumn the rotten leaves form a crumbly rich surface mulch.
To be left for a second or third year will allow for increased decomposition of the leaf matter and this, with its added microbes, can then be used as a conditioner and soil enhancer which can be dug into the soil to aid in water retention for drier ground and for improving drainage in heavier soils. If preferred a leaf storage bin can be constructed and there are numerous methods of construction, one composed of chicken wire which permits air to travel through, being the
most simple. Once a large amount of leaves have been placed into the bin, apply a sprinkling of water and then cover with some black plastic sheeting on top to encourage the decomposition.
Leaf mulch is high in nutrients which will pass slowly into the ground below. As with all mulches it prevents the ground from drying out during the summer months and from becoming too cold or even freezing in the winter months. It also reduces the opportunity for the unwanted plants referred to as weeds to grow.
The leaves can be gathered regularly as they fall with hand tools such as a rake or broom, a lawn mower can be used on a higher setting to collect leaves from the lawn whilst shredding at the same time. If the leaves are not collected soon after falling, then they will dry out and loose their nutrients.
If your own garden is devoid of fallen leaves then maybe ask the neighbours, I am sure they would be happy with the assistance of leaf clearing. Or vice-versa, others in the neighbourhood may require leaf mulch too. The coming together can create a community free leaf mulch, this way the local gardens will never be without a mulch or compost.
It is advisable to avoid leaves which have been lying on roadsides, they may contain toxins. Certain leaves will break down faster than others, Horse Chestnut leaves taking longer than Oak leaves. The leaves from Walnut and Eucalyptus do contain a natural herbicide, this may inhibit the growth of plants within the area the mulch or mould is
The splendour of the autumnal colours from bright yellow to orange to a crimson red, it is one of natures finest displays, the deciduous trees then sleeping for the winter months. They took nutrients from the ground to assist their growth during spring and summer, and now is the time to give back to nature and this can be achieved by gathering the fallen
leaves and making a leaf mulch or mould full of natural nutrients.

It is a month which at times can show signs of spring and entice one to partake in some gardening. Indeed, if the weather is genial then February is the ideal month to prune those plants which belong to the RHS category of Group Six pruning.
Essentially, these are the plants which flower late summer to autumn and on the current new seasons stems and growth.
Examples of plants which adhere to Group Six pruning are:
As these shrubs flower on the same years growth a hard prune is required during the month of February and as in the case of the hardy Fuschias almost down to ground level, this can be extremely therapeutic too for the person who is doing the pruning. Perovskia ‘Blue Spire’ which exhibits a wonderful display of blue-lilac flowers, also known as Russian Sage, will benefit immensely from a hard prune back to its basal shoots. Perovskia thrives in many coastal areas and in many soil types and with aromatic leaves akin to sage and an appearance similar to lavender it makes an excellent low lying hedgerow.
Buddleja Davidii also known as the ‘Butterfly Bush’ can be cut down, using large pruners, to approximately half a metre from the ground, this will encourage upright shoots with a slight arching habit and will be greatly appreciated by the butterflies.
As a rule of thumb for shrubs which adhere to Group Six pruning, cut back the previous years flowering stems to one or two buds from the older framework.
Certain types of Clematis will also be required to have a hard prune in February, this is particularly the case for Herbaceous Clematis, Gypsy Queen and Clematis Viticella. They all flower on the current seasons growth in late summer and if they are not pruned annually the stems will be devoid of flowers and only up high will the flowers grow and most often amongst a tangled mass of growth. It must be noted that Clematis has its own pruning group classification, those which flower in late summer fall into Clematis Group 3, whereas, those which flower in early summer and on older wood or the previous years growth fall into Clematis Group 2. If unsure when to prune, then observe the time of year the Clematis will come into flower.
For the kitchen gardeners, autumn raspberries will fall into Pruning Group Six.
All old canes should be cut back down to ground level in February and the new canes will start to grow in spring and then fruit in late summer. It is important not to mistake summer raspberries for the autumn variety, as they fruit on the previous years canes, which would result in a loss of crop.

MISTLETOE the ‘air-plant’
Mistletoe, its true name being Viscum Album, is synonymous with this time of year particularly with the tradition of ‘Kissing under the Mistletoe’.
There are many ancient mistletoe traditions, the best known being the Scandinavian legend Balder, the god of peace, who was killed by an arrow made from mistletoe and was resurrected by the other deities. The goddess of love was then entrusted with the
mistletoe and regarded it as symbol of love, hence, any person passing beneath shall receive a kiss. Mistletoe is an evergreen parasitic shrub with white viscous berries and of the natural order Loranthaceae. It is a native of Europe and North Asia and requires a host plant with which to grow on, such as an apple tree in the garden. Orchards benefit from the growing of mistletoe on their fruit trees, thus yielding a return during the winter months when the trees are dormant. This is what makes the mistletoe so unique, it is also known as an ‘air-plant’ that is it is not rooted to the ground but it attaches itself to other plants, the correct
name for such a plant is an Epiphyte, this word originating from the Greek words epi (upon) and phyton (plant).
The bark and the leathery mistletoe leaves are of a yellow-green colour and are oval- lance-shaped, mostly in pairs. In spring, there are inconspicuous yellow flowers which consist of four triangular sepals, a similar number of anthers and an ovary with simple stigma. This is followed by poisonous white berries, however, they are devoured by birds most notably the Mistle Thrush, the seeds becoming attached to the branches of trees by their agency. On germination the embryo pierces the bark and penetrates to the wood and here it draws most of its food from the tree, but it manufactures carbohydrates in its leaves.The constituents of mistletoe can vary due to the host plant with which it grows on
and it is believed the Druids regarded the mistletoe which grew on an Oak was the superior, although Oak being a rare host. It possible to grow your own mistletoe and there are numerous fact sheets and websites available including the following:
