Garden Design Ideas With Conifers

Conifers have become a favourite of landscapers and gardeners alike due to the huge range of varieties that are available for ornamental purposes. All sorts of shapes, sizes, foliage textures and colours have been cultivated in order to provide design solutions for the innovative garden designer. The use of conifers as feature elements of a garden is a strategy that is often used very successfully.

They can be effectively incorporated into many differing styles of garden including the english traditional (sometimes consisting almost entirely of conifers), rockeries (dwarf and ground covers), to Japanese symbolic style gardens where a ragged and worn looking cupressus is in stark contrast to the serene and ordered nature of the garden. Conifers could also be incorporated effectively in informal or native bush gardens, depending on the species/cultivars chosen. There is a conifer for just about any situation in your garden.

Conifers come in a huge variety of shapes, sizes ranging from large trees to small prostrate ground covers, from rounded forms to upright conical shapes to sprawling types. The height of conifers varies from only 20cm or so for some of the creeping types to the giant Californian Redwoods, hundreds of feet tall.

Although conifers are not renowned for their vast array of colourful flowers, their foliage does come in a large range of colour shades and textures; and the great thing is that these can be used for affect all year round (unlike plants that flower for only a short time and then become another obscure green mass of leaf). Most conifers are cool climate plants and generally have a characteristic resinous fragrance. The majority are evergreens. The foliage of conifers can be short and spiky, or long and needle like. Colour variations range from greens, blue greys, golds & yellows, to purplish bronze and more. Colour may also vary according to the season, for example, new spring growth may be light green or golden yellow which turns darker with age, or the foliage of some might turn purplish or bronzish in colour during the cooler months.

A well planned conifer bed can provide colour all year round. One trick is to use a variety of different coloured foliage plants and different shapes planted together so that they contrast one with another.  

USING CONIFERS

Common uses for conifers in a park or garden include:
 - for hedging (both low and tall);
 - as topiary specimens;
 - stand alone specimen trees;
 - as part of a shrubbery, often as a contrast plant;
 - low growing or prostrate shrubs as groundcovers or cascading down a slope,
   over rocks or a wall;
 - windbreaks - but be careful with planting distances as many conifers have a
   tendency to self prune (dropping their lower branches) if planted to close
   together, which makes them ineffective as a windbreak, as the wind gets
   funnelled beneath the plants near ground level;
 - as specimens in containers;
 - as 'Christmas Trees' with suitable varieties kept in containers and bought indoors
   for a short time during the christmas period;
 - dwarf varieties can be used as low borders along a pathway or to delineate a
   garden bed;
 - to frame a building or attractive view.
