Border Plants

BORDER PLANTS

Modern gardens can be an extension of a home's living space. The indoor living space is subject to fashion as replacement furniture is modernised and moved around to maintain interest and keep up to date with new technologies and the latest fashions.

This suits comfort, taste, appearance and socialising.

The garden, (the outdoor living space) is just the same as ideas change with healthy living through fresh foods and exercise, relaxing on the patio after a stressful days work and socialising around a barbecue being just as important as choice of that special must have plant.

The garden has developed over the years from the narrow cottage garden border where a few choice plants would grow, often from cuttings or suckers obtained from a friend's garden. These often had scented flowers such as border pinks, iris and herbs such as thyme, sage, lavender, rosemary and mint to be used in the kitchen. Borders often had honeysuckle growing up border fences.

Garden space got bigger after the last war when there was a steady demand for fresh vegetables and some fruit was necessary as there was no supermarkets, and people wanted to grow colourful flowers to raise spirits. There was a continuous flow of new vegetable varieties, fruit, flowers and other garden plants.

The garden enthusiast could indulge in a massive extension in the range of plants available to fill their borders. Slowly garden centres and specialist nurseries have grown to meet this need to try something new, different or just the latest fashion.

The Modern Garden

The pace of change has been huge as gardens are now smaller to meet housing needs where space for building gets priority over garden space. However, the pace of life is faster, more demanding and stressful and the need for a place to relax in all the more relevant. The garden may be smaller but can still be designed as a place to chill out, and be visually attractive and easy to look after.

Today's popular plants are those that are easy to grow, pest and disease free, have long lasting colour from flowers or foliage, give good ground cover and are not invasive or grow too tall. People want colour but without too much effort.

The herbaceous border would be fine if the plants did not need staking and climbers are great if they are self clinging. If only it were that easy.

It is possible to create that attractive garden border with colour all year round and easy to maintain, but most often there is a fair bit of graft to perform before we reach for the sun lounger on our sunny patio.

Choosing Border Plants

Anemone Honorine Jobert

Choice of plants is always a personal matter, but garden centres have such a wide choice that plants can be tried for a few years then dug up to be replaced by the next garden fashion accessory if they have any failings. My own garden goes through major transformations as many of my previous plant favourites especially roses, succumb to diseases in clean air devoid of sulphur. Global warming will also affect the choice of plant as warmer summers and winters are not to every plants liking and we also take the opportunity to try those more exotic plants that we might manage in a better climate. I'm assuming that our Scottish climate will get warmer and hoping that we wont just get warmer summer rain and a lot more of it. What's the point of a warm wet summer and a dry winter and spring!

Spray chrysanthemums

A larger garden has scope to have colour all year round with a wide choice of plants, but many smaller gardens can be an absolute treasure with just one well grown plant giving a burst of colour for a couple of weeks that will be remembered for a long time. I have noted several Dundee gardens with one brilliant azalea, one Rhododendron praecox, one philadelphus, or oriental poppies.

Wherever there is only room for a very limited number of plants it is better to select good plant combinations where they will all be at their best at the same time. If you have a garden where there is a wee bit of colour over many months but scattered around here and there, the impact is lost. Try a red quince under-planted with daffodils, or a Forsythia under-planted with Fosteriana tulip Red Emperor. A later early summer combination is flag iris, oriental poppies and pyrethrum. Another good spring combination is the lemon yellow broom Cytisus praecox amongst a drift of dwarf early red tulips and blue grape hyacinths all flowering together.

It is important to make the most from the space available, so plants can be very accommodating growing happily together, but at different depths. My winter border of coloured stemmed shrubs are attractive from October to the end of February. Then they get pruned to ground level as the snowdrops take pride of place to be replaced by the crocus two weeks later. Another couple of weeks later then the tulips take over and in July my lilies get the border to themselves being supported by the young shoots of my cornus and other coloured stemmed shrubs. Lilies are also useful companions to dwarf Japanese azaleas where they both grow happily together.

All Year Round Colour

Fuchsia Mrs Popple

Where there is scope for a range of border plantings consider trying to get year round colour. I have borders around all sides of my house so those that need a warm south border will be different from those in the northern shady border. No point putting crocus here as they need sun to open up the flowers, but snowdrops are perfect as they are happy in the shade.

My borders start the flowering season in winter with Jasmine climbing over a fence under-planted with snowdrops. Aconites are nearby in a drift surrounding a pure white Christmas Rose, the Hellebore.

My first herbaceous plants are the yellow Doronicum next to the blue Pulmonaria, then a drift of hyacinths pushes through the bed of flag iris, extending the flowering season.

The garden bursts with colour in spring and early summer but by August other garden areas have their moment. Fuchsia Mrs Popple, having just survived last winter is now in full flower and combines well with the white Anemone Honorine Jubert.

A spring drift of another Anemone called blanda dies down for a summer rest to be replaced with Cyclamen hederifolium.

As autumn approaches the michaelmas daisies have their display and this year I am also trying a drift of spray chrysanthemums, usually grown for cut flower but with tops removed to encourage them to branch into a wide plant which will be self supporting. I've no wish to stake them.

IMPACT ON GARDENS FROM GLOBAL WARMING

Childhood memories of sunny summers getting burnt on Broughty Ferry beach followed by hard winters when we could ice skate on the roads, (very few cars around) and have plenty of snow for sledging, snowmen and igloos, all belong to my generation. I was not able to offer my young family the same fun as they grew up with a lot less snow visible and although the summers seemed fine there was a lot more wet days if your holiday was at home.

However there was always the extreme conditions of a very cold winter, six foot snow drifts, local floods you will not forget, and every ten to fifteen years a very hot summer.

My gardening career started during the 1959 summer heatwave as an apprentice gardener in Dundee Parks Dept. working in the Howff cemetery. A glorious three months ended when the rains came in September and flooded the Howff and many other places.

Gardening activities force you to work with the weather so you become aware of weather patterns and how they change over your lifetime.

Date Palm

I was working in Darlington Parks Dept during the 1976 heatwave. Our main bedding displays relied on geraniums and petunias which could not have been better. We won the Regional Britain in Bloom Award. However the heatwave had other effects, especially on the greenfly pests. Farmers in east Anglia were applying high levels of nitrogen fertiliser to increase grain yields. This also gave a lot more leaf content which combined with the hot summer caused breeding greenfly to reach plague proportions. Once they had devastated East Anglia they took to the air to find new pastures. A drift extended from Kent to Newcastle and scientists estimated the weight to be in excess of 200,000 tons of greenfly.

That summer I was on Scarborough beach when the sky darkened from the sea and expecting a thunderstorm got quite a shock when the plague of greenfly arrived.

Hitchcock could not have done it better!! The sea and sand turned green and everyone ran for cover. The following year there was a mini plague of ladybirds which had been feasting on the greenfly.

Gardens, farm crops and the outdoor natural landscape will all be affected as global warming changes our climate. Future generations will need to adapt to climate change as this generation embraces the changes, assesses the impact and takes steps to alleviate the problems.

Changing weather patterns

The UK has always had a different local climate for different areas, being affected by proximity to the sea, and the gulf stream, hills and mountains, built up urban areas, winds and geography. The south is generally warmer than the north, the west wetter than the east, but extreme weather conditions can affect any area with tornadoes in the Midlands, hurricanes in the south and flooding just about anywhere. Counting 2010 we have had four very wet years following the record breaking heatwave of 2006. June was truly flaming, but then the rains came in July and hopefully when you read this it will have stopped. However the south of the country has been basking in a glorious heatwave with gardens desperate for water. My garden hose has not been used for four years.

Mild winters have seen the snowdrops flower a month earlier than normal followed by other spring bulbs all early. Grass cutting always started first week in April, but now it is more likely to be mid March and the season finishes, not when the grass stops growing but when it is too wet to put the mower over the ground.

The Good

Fig Brown Turkey

Gardeners love to try out new plants and now with a warmer climate the time is right to experiment with those exotics we admire from holidays abroad.

There is a whole range of palm trees worthy of planting from the cabbage palm, Cordyline australis to the date palm, Phoenix canariensis and those colourful Bougainvillea's might one day become common in UK.

It may be normal to grow our tomatoes outdoors rather than under glass and sweet corn could become a major crop.

Already I am having success with peaches and figs and some types of outdoor grape vines and as warming continues it is quite possible that Scotland could have numerous vineyards especially as it may become too hot for their success in France.

Pete Gottgens is prepared to be a leader in this field by establishing a vineyard on the banks of Loch Tay with his experience of growing grapes in South Africa. He hopes for success by choosing an early variety, Solaris suited for a northern location. We may no longer have very cold winters, (last winter being an extreme one off), and our summers may be getting warmer, but that is tempered with the prospect of a wetter summer and less sunshine hours. Scotland's first vineyard will be a barometer for the future. Gardeners will be encouraged to experiment with a range of grape varieties grown in more favourable locations with less incidence of rainfall and more sunshine hours.

In time, cherries, nectarines, apricots, citrus fruits and dare I say bananas and olives could well be grown on our Carse of Gowrie.

The woodland landscape could see more sweet chestnuts, walnuts, and eucalyptus.

The Bad

A climate that progressively gets warmer will affect many of our trees e.g. beech does not like dry soils. Herbaceous borders, rhododendrons, azaleas and lawns require moist soils so could suffer from too dry conditions. Soft fruit including raspberries, strawberries and blueberries would struggle, but saskatoons can tolerate drier conditions.

Many fruit plants require a period of winter chill to set fruit buds without which the following years crop is greatly reduced, e.g. blackcurrants.

Sweet Corn

It was always good gardening practice on allotments to complete winter digging before Christmas leaving the surface rough to allow frosts to break down the soil surface, but with mild and wet winters good digging opportunities are few and far between. In spring a poor soil surface restricts the germination of seeds.

Plum trees flower so early that there is often not enough insects around to pollinate the flowers thus reducing the crop. I do not mind hand pollinating my smaller peach tree every day with a fine sable brush in March, but the plum is twenty feet tall. Forget it !!

The Ugly

The changing climate not only affects plants, but also animals, insects and diseases.

Mild wet winters and wetter summers up north give rise to the spread of damping off, blight, root rots, scab and mildew. Potato blight can be problematic so make sure the variety has some tolerance or resistance to it. Similarly roses are suffering badly from black spot, rust and mildew so only grow those varieties strong enough to withstand an attack.

However the root rot, phytophthora has many types that affect many different plants and could become a major problem in gardens as well as raspberry fields.

Two generations from now could see a massive change in the horticultural and agricultural landscape.
