  • Keeping on Keeping on

    By on October 16, 2017

    We may be nearing the end of October but that does not mean that the garden needs to be running out of steam. There are many places that we can look for colour and interest and also scent. The stars of the show at the moment are naturally the deciduous trees.

    Cercidiphyllum

    One of the foremost genera for me is the Katsura tree or Cercidiphyllum japonicum. Ultimately this is perhaps a tree for the largest garden as it can reach a substantial size, indeed it is the largest tree in Asia. The leaves are rounded and at the end of the year turn wonderful shades of red, gold and orange. Best of all is the scent which is carried powerfully all around the tree and smells variously of burnt sugar or toffee apples. It is by no means one of the fastest growing trees so you could plant one in order to enjoy it while it is relatively young. There are also dwarf cultivars which are really just very slow growing forms of the species including ‘Boyd’s Dwarf’, ‘Herkenrode Dwarf’ and ‘Kreukenberg Dwarf’. These could be accommodated in even an average garden.

    Sorbus is another genus which I defy anyone not to love. The family is broadly split into two groups, the Aria section of white beams and the Rowans which have light foliage made up of many leaflets. These make excellent garden trees as they do not cast too deep a shade as to exclude things from growing underneath. At this time of year the foliage is deeply alight and glowing. There are a huge number of cultivars with different leaf shapes, berry colour etc. If I had to pick one it would be Sorbus commixta which hails from Russia, Japan and Korea. It has a rather columnar habit with orange red fruits and the cultivar ‘Olympic Flame’ is perhaps one of
    the best of all trees for autumn colour.

    Viburnum xanthocarpum

    Amongst the best shrubs for berries are the Viburnums and amongst this family the Guelder rose or Viburnum opulus holds a chief place. The large maple like foliage positively glows in autumn along with glistening fruits which take on a translucent quality. My favourite is V.o. ‘Xanthocarpum’ which has orange yellow fruits that stand out  like pearls on a necklace. Undoubtedly, the most unusual if not downright sinister fruits belong to Decaisnea fargesii which hails from China and the Himalayas. The flowers are
    yellow-green borne in May but by September and October large groups of metallic blue pods like oversized broad beans hang beneath the foliage. The shape and colour gives the plant it’s common name of drowned or dead man’s fingers. Inside is a squishy mixture of pulp and seeds.

    Now is the best time to plant bulbs but it is also the best time to enjoy one in particular. Nerine bowdenii, a species of flowering plant in the Amaryllidacae family. Planted shallowly in full sun the narrow strap shaped leaves give way to clusters of bright pink flowers held in large umbels. The plant itself originates from South Africa though it is reliably hardy unless waterlogged and it is worth making sure there is good drainage. Clumps will increase rapidly and can be divided after flowering. After a disappointing summer it is reassuring to know that there is still so much to enjoy.

  • The Wisdom of Plants

    By on October 3, 2017

    Outside my window the trees are beginning to take on their autumn hue and many are already falling especially the horse chestnuts which have already been decimated by leaf miners. These insects live between the upper and lower surfaces of the leaf eating them from the inside. When the leaves fall they overwinter ready to reinfect the new leaves in spring. The multiplicity of different leaf sizes and shapes should give us all pause for thought. Why don’t all leaves look the same?

    Scientists have long known about the factors that limit leaf size. Leaves exist to capture sunlight for photosynthesis, so the larger the surface area, the more sun light can be captured. However, the size of the leaf cannot exceed the amount of available water. The evaporation of water from the leaves cools the leaves as well as drawing more water up from the roots to
    replace it. Thus a leaf which outgrows the availability of water will soon scorch in strong sunshine. In this way any amount of water creates an impetus towards growth whilst the availability and strength of sunlight restricts growth. Plants find a happy medium between the two according to their own specific set of circumstances.

    Yet recently, scientists working in Australia have discovered another variable. Cold. Plants may be just as wary of catching a chill as of catching too many hours of sunshine.  The more likely a plant is to experience freezing temperatures the more it will reduce the size of its leaves.

    Evolution & ecology produce leaf shapes

    But still leaves have different shapes as well as different sizes, something that can only be accounted for through myriad of tiny adaptations over the enormity of evolutionary time. Each small adaptation is passed down in genetic form from parent to progeny. The evolutionary and ecological history of a plant species is written in the shape and size of the leaf. Style also mirrors function when it comes to plants. They don’t dress up just for our benefit. Getting the style of leaf right for a specific environment can be a matter of life and death. Large round leaves gain more sunlight whilst leaves with sharper edges and rough textures are able to to shade themselves from the strongest rays preventing them from becoming scorched.  Large leaves, like those of a banana grow where cold is not a problem whilst small tight leaves such as bundles of pine leaves keep out the cold.

    Leaf Shapes

    An individual plant may even go so far as to change the characteristics of the leaf according to its own circumstances, how much shade falls on it or what the atmosphere around it is like. Plants are beset by many ecological challenges. Their response over time has been ingenious and hopefully in an era of man made climate change this will prove their salvation and ours.

  • The Ripeness and the Harvest

    By on September 18, 2017

    There is a wild abundance in our fruit garden at the moment particularly on the top fruits. Though the late summer has been poor the early part of the year was good for pollination with plenty of fine warm days that started early and no frosts to speak of. This meant that the flowers and reproductive parts of the plants were undamaged and that foraging insects had plenty of opportunity to do their work. This meant a good fruit set and because ripening takes place over a long period the cold, wet, dark summer has not affected the ripening.

    Plums, damsons, apples and pears are weighing down the branches. But what to do with all this abundance? I know that I have extolled the virtues of preserving fruit with alcohol before but winter is coming! I like to use fruit as much as possible especially with meat. Try mixing together some mustard and honey and spreading it over chicken pieces. Pour some oil in a roasting tin and put in a couple of onions and half a dozen dessert plums such as ‘Victoria’ which you have halved and stoned. Add some fresh thyme and roast for 30-40 minutes and serve with mashed potatoes or polenta.  Of course the classic dish has to be the crumble and I’m sure that there are
    as many different takes on this classic as there are people out there making it. To me you can’t beat apples from the garden (whether they are dessert or cooking it doesn’t seem to matter) and blackberries from the hedgerows around.

    If you don’t yet have a fruit tree then you should think about planting one. Even if you have a small garden there are dwarfing varieties of apples and
    pears on the market and you should find a good selection at your local nursery. There are also many varieties suitable for containers. The very best time to plant is when the trees are dormant and leafless from late October to March. This means that you have time now to be looking in catalogues from mail order suppliers, online or at the nursery to find what you want. Great as it is to have one of everything or to go for the unusual it is better to grow what you will use the most. There are many multi-purpose varieties of apple that are available.

    Apples are one of the easiest tree fruits to cultivate and they make a good looking garden tree as well as a useful one. The blossom is pink and white and the fruit can be used in many different ways. ‘James Grieve’ is one such variety which is excellent for cooking or eating straight from the tree. So called ‘Family’ trees are also available which have several varieties are grafted onto one rootstock. Buy one from a good nursery as the vigour of each variety needs to be matched if the resulting tree is to grow evenly. If you are planting a whole orchard it is better to dig over the whole area and plant all at the same time but if you are just adding one or two fruit trees then dig individual holes. Make sure that the hole you dig is wider and deeper than the rootball and then you can fill in the gaps with soil enriched with organic matter. Firm the soil down gently and water well. Don’t forget to support your new trees. Whether bare root or pot grown the trees will need staking for their first year and dwarf trees will need strong stakes for their whole life. If you are thinking of buying already trained trees then they will need support on wires, trellis or fences.

    What more can I say except “Eat, Drink and Be Merry!”

  • Amongst the back woods of North Carolina

    By on September 5, 2017
    The Smoky Mountains

    The Smoky Mountains

    August is holiday time and it seems that everybody has been travelling. I was no exception having planned a getaway to North Carolina a state on the eastern coast of the USA. The state is situated along the Appalachian mountains which run like a spine down the eastern seaboard of the country from Maine down to Georgia. Anybody familiar with the work of Bill Bryson will have read his hilarious account of hiking the Appalachian Trail.

    North America has a huge range of conditions from arctic to subtropical and climate is the main factor covering their distribution. Altitude and land mass are also important as the same trees that can be found growing high in the Appalachians can grow near sea level in Canada whilst the Great Lakes create a warmer climate than if the area were all land. Similarly atmosphere also affects habitat, whilst some trees can tolerate extreme aridity others require more rainfall or humidity.

    Walnut fruit

    North Carolina is extremely fortunate in having over six hundred species of native trees, shrubs and vines as well as countless herbaceous species which thrive in the diverse climate from mountains to piedmont to coast. The large
    forests are mixed with coniferous and deciduous species. When I was there this year I was immediately impressed with the large numbers of walnuts which we some of the most visible trees owing to the large fruits that were held dangling from the branches. The most common species was the black walnut (Juglans nigra). The leaves one to two foot long divided into leaflets which are smooth above and hairy below. The large fruits were two uncles in diameter green on the outside, with a yellowish husk that stained hands and fingers like tobacco. The trees were between 60 and 100 feet high and grew plentifully. Many of the trees I saw were home to tent
    caterpillars. What at first I took to be spider webs was the home of these caterpillars, six species of which occur in North America. They are a social caterpillar building nests from silk which hang in the branches of trees. They are often considered a pest because they can defoliate an entire tree. Though I am no expert they looked like Malacosoma americanum as well as something from a horror film!

     Tulip tree seedling

    Another recognisable species which abounded in impressive stands was that well loved denizen of gardens and parks the tulip tree (Liriodendron tulipifera). Growing as they did in close proximity to other trees they had not developed the large rounded crowns that you see in our gardens and parks. Nevertheless they were impressive at 80-100 feet tall though they can reach 150 feet. Numerous seedlings sprouted up wherever you went waiting for an older tree to fall so they can shoot up. Many of the most impressive of
    North Carolina’s native trees are chronicled by the Archangel Tree Archive which is worth looking at.

    As in many deciduous forests spring is one of the most colourful seasons and the large areas covered by Rhododendron catawbiense hinted at what must be a spectacular sight when the purple flowers emerged. They formed dense thickets with large glossy leaves that were impressive even out of flower.

     Paris ssp

    Beneath the shrub layer many other plants abounded in the moist humus rich medium decomposing on the forest floor. I was struck by the preponderance of trillium though alas too late for flowers! I could also see Paris plants made obvious by the whorl of leaves clasping the stem. Some were beginning to ripen their fruit capsules. All in all it was a fantastic visit to one of the most bio diverse areas of the world.

  • A Few Perennial Favourites

    By on July 20, 2017

    Broad beans. This might be an unusual way to start a sentence but I thought I would mention how well my early sowings had done. They have come to an end now but we have enjoyed them. Because they are such mainstays of the vegetable patch and I have been patiently expecting them since they were sown last winter it is like saying goodbye to old friends. I prefer to pick them when the pods are small and the beans only about the size of a 5p coin. They can be used raw as an addition to salads or put straight into a risotto and allowed to cook with the rice. My absolute favourite has to be broad beans liver and bacon with the liver floured, fried gently and only just done. The gravy is to die for though it’s hard to find companions who will eat offal so it is often a solitary pleasure.

    I have heard many tales of woe from growers of runner beans and peas this year who planted and were caught out by a dry spell. I have to confess to a some disappointment myself. A family holiday meant that the pigeons enjoyed the peas before I did and my next batch of peas and beans have needed a lot of water to get away at all.

    I have had more success in the herbaceous border and with my containers. The regale lily bulbs (Lilium regale) have put on a magnificent show. The large trumpet flowers white inside with a yellow throat and a pink back are filling the warm air with scent. It is a thick heavy scent and you feel that you have to wade through it once it has you in its grasp. Of all the bulbs that I take from containers and plant in the garden these lilies are some of the most successful. They like plenty of sun and good drainage. I always put a handful of gravel underneath them when planting. I usually plant in groups digging a hole big enough to lift them straight from the container into the ground without breaking them apart.

    Lilium regale

    Another scented favourite are the Philadelphus also called mock orange. They are members of the same family as hydrangea and are really indispensable garden shrubs. They give a good display even on poor or chalky soils. Most have white fragrant flowers borne in June or July. The old flowered wood should be cut out after flowering leaving wood produced this season to take its place. They can become large shrubs over time though if this happens the whole thing can be cut to ground level from where new growth will spring.  The most commonly encountered is Philadelphus coronarius which is a strong upright growing species even in dry ground. The cultivar ‘Virginal’ is still perhaps the best double.

    Danger does lurk deep within the border in the hooded flowers of monkshood or aconitum. Though highly poisonous they are worth having for bed use as they are so amenable as to soil and aspect. A. x bicolor, A. carmichaelii and A. napellus are all good to have and will spread the flowering season from early summer to Autumn.

    Aconitum vulparia also known as A. lycoctonum is also worth growing. It gets its common name ‘Wolf’s Bane’ because it was used as a poisonous bait for wolves in olden    days. Like its blue relatives it has dark divided green leaves though the hooded flower is white or parchment colour and quite tall.

    From edible beginnings to poisonous ends the garden has everything to offer.
