Conifers have had a bad press recently, they've even been
talked about in parliament . So when you mention them to many people and
suggest that they should be planted in the garden, the initial reaction is often
as if you're suggesting they join you in a spot of devil worshipping and that
they may wish to install their own altar.
The problem is that the word "conifer" has
become synonymous with Cupressus x lleylandii, that bully boy of the
horticultural world.
Lleylandii
form large, fast growing dense evergreen barriers, so they should be ideally
suited to the task of hedging. However Cupressus x lleylandii is a forest
tree that will quickly and happily grow to 70 feet tall or more with a proportional
width. Now imagine that I was selling hedging plants and you had a garden about
30 feet by 40 feet. I then advise you that you should plant fast growing trees
that can attain 70 feet, at intervals of 2 feet all around the garden. You would
probably not take this advice!
But this is exactly what has happened over the last 25 years
or so, especially on new housing estates. Lleylandii are just not suitable
except for very tall hedges in very large gardens.
But I come not to bury conifers, I come
to praise them!
Conifers
are a very large and diverse group of shrubs and trees. Like all large and
diverse groups, there are good ones and there bad ones. Pretty ones and ugly
ones. Some that are excellent in some situations, but useless in others, and
like all garden plants they are best when situated appropriately.
Conifers have the advantages that they are evergreen and
tend to look the same all year round, this is also the disadvantage with conifers,
if they are planted in the wrong place. They can appear dull and unchanging
if planted in groups without other types of plants. Planted in the right place,
they can give structure and permanence to your garden. They are architectural
plants and should be used as such to give your garden a "skeleton" or framework
around which you arrange the other more seasonally varied plants.
One of the main reasons, I like conifers is for the colour
of the foliage of certain varieties. I love glaucous blue leaves, and there
are some conifers that have the best examples of this in the plant kingdom.
The colour comes out best in full sun, in partial shade, they tend to revert
to green.
How to use
conifers:
To give a permanent backdrop for more delicate
flowers or the wispy seed heads of ornamental grasses.
Grow the ground-covering types to suppress weed
growth. They are excellent at this and are more easily kept in check than many
ground cover plants as they grow from a single point, rather than rooting as
they go. This also means that you can grow spring bulbs up through the foliage
away from the stem without interfering too much either bulbs or conifer.
Grow ground covering types to hide manhole covers
while allowing access if needed.
If you do want to use them as a hedge, then mix
them in with other evergreens such as Cotoneaster or Pyracantha
to give a less formal but nonetheless very effective barrier.
Block out an unwelcome or ugly view.
Don't have too many conifers or other evergreens in a garden or planting,
no more than about a third of the total.

Top Conifers
There are literally thousands of different named varieties
of conifers and it can be very difficult to track a particular one down that
may not be very widely grown. Frequently, you can go for similar but different
named variety that will not be so different, ask advice from the garden centre
or nursery if you're not sure.
The coloured (i.e. not just plain green) varieties tend to
colour up best in full sun.
If you have less than ideal conditions, use the following
as a guide (but not a guarantee!)
Chamaecyparis - withstand exposure
and dry conditions once established.
Juniperus - Withstand cold-exposed
conditions, not keen on wet.
Picea - withstand cold-exposed
conditions and also wet-moist (not soggy)
Thuja - often the hardiest withstanding
most conditions, wet-moist, dry, cold-exposed, shade.
Abies nordmanniana "golden spreader"
- grows to a pyramid shape about 3ft high by about 3ft wide with green-yellow
needles that turn bright gold in winter.
