It's quite common these days to discover that certain
plant species that you planned to include in a design, while appearing
in the design gardening books, are difficult to find in the garden
nurseries. They used to be sold by the garden centers, but then become
increasingly rare and even entirely unavailable. In general, the reason
for this of course is that these species lose some of their popularity
and therefore the demand for them declines. It may be tempting to think
that because a garden center sales person pulls a face at the mention
of a certain plant, and says "I am afraid there's not much call for
that these days", and then adds, "Well I suppose we could find it for
you if you insist", that the species concerned is basically inferior.
Unfortunately many excellent plants have either fallen by the way side
or are in danger of doing so, and as a result we actually have less
genuinely appropriate varieties to choose from. I'll present here some
examples from my own 20 years plus experience gardening in Israel.
There
are a number of reasons that certain garden species, whether they be
flowering, foliage plants or trees, fall out of favour. A common one is
that the plant is incorrectly used by gardeners, professional or
otherwise. For example, the fabulous shrub Duranta erecta was heavily
planted as a sheared hedge, a growing form unsuited to it, and
particularly to the variegated variety. The plant became so discredited
that no one wanted you to plant it for them. Yet as an isolated
specimen in a shrub grouping it can be superb.
Another reason for
plants becoming unpopular is that many gardeners, particularly home,
amateur ones, are unaware of some simple actions that if not
undertaken, mean that the plant becomes ugly and unsightly. Take the
Ice plant (Lampranthus roseus) for instance. As a low growing ground
cover, its spring flower display is not only spectacular, but in my
view is virtually unique in the gardening world. Yet the plant tends to
look ragged and untidy for large parts of the year, unless the simple
expedient of clipping back the plant, BEFORE all the flowers have withered, is carried out. (For fuller discussion on how to grow ice plants click on Articles at

Finally, some plants simply go
out of fashion. This is the most unnecessary and dare I say, most
stupid reason of all. Fashion is the killer of good planting schemes.
The great gardens of the world are generally immune to it, as are top
garden designers. (At least as far as plants are concerned – hard
landscaping being another matter)
I first became aware of this
when visiting the magnificent Waddesdon Manor in England some years
ago. There, growing proudly in a conservatory to protect it from the
cold, was the most despised garden plant in my country – Plumgago
auriculata. Another example is the Natal plum (Carissa macrocarpa),
arguably one of the most beautiful and suitable bushes for a dry
climate. Fortunately, there were just enough designers in Israel
demanding it, to prevent it disappearing altogether. I am pleased to
say it has started to become fashionable again!

am the former head gardener of the Jerusalem Botanical Garden, but now
concentrate on building gardens for private home owners.
