I was standing at the counter at the weekend, with a few
bulbs, thinking I was a bit crazy to be thinking of planting daffodils in such
a sustained dry spell, when I noticed a young woman coming towards me, pushing
a trolley loaded up with shrubs. I
thought she was really going to struggle with keeping her new plants alive in
the drought, and felt rather superior. You
know the sort of thing I mean – experienced gardener smiling at a greenhorn who
was going to make an elementary gardening mistake.
Turns out I could not have been more wrong. As she got closer I could see that plants she
had chosen, and it became very apparent she was very much more switched on to environmental
concerns, and aware of the certainties of climate change, as she was clearly
planting a grey garden for a sunny and dry situation.
She had started out with some lavender. I could not see what variety they were (I did
not want to pry too much) but they were English forms, with flower spikes hovering
over the bushes. There has been a huge
upsurge in interest in these plants, and there are probably hundreds of
different forms available in the market, ranging from deep purple through to
sort-of-pinks (although you need rose coloured glasses to really think of them
as pink), to a neutral shade sometimes called cream or white, as well as all
sorts of mauves and soft purples, and even greenish hues.
I have found these will cope with growing in almost no soil –
we have an area alongside the driveway that is simply compacted fill, and has
little or no nutriment. I popped a
lavender in among the few other things that will tolerate it, and it has
flourished, even casting seeds that germinate in my near-by iris seedling bed. I suspect the less the food lavenders get the
hardier they grow, and the more concentrated their scent becomes.
The French lavender, L.
stoechas, is probably the best for the average garden, having large flowers
with the characteristic rabbit’s ears petals on the spikes, and again is
available in lots of different forms.
With all garden lavenders, it pays to make sure they are trimmed each
year after flowering. It pays to trim
back by about a third to encourage new growth.
Among the other shrubs in the young lady’s trolley I noticed
a silver-leaved favourite of mine, Convolvulus
cneorum. This is a prolific
flowering, low growing shrub growing probably 50cm high and about a metre
across. It has evergreen (or should I
say eversilver) foliage that covers the plant all year round, then starting in
spring starts a crop of cup shaped white
flowers which and continue throughout
the summer and autumn months.
Like most silver-leaved plants it does best in a sunny free-draining
position – it hates damp feet and does not tolerate shade. It does not like severe frosts as it is establishing,
but after that will cope with anything a Wairarapa winter throws at it. It is not often used this way, but it makes an
interesting small hedge, providing a great contrast for larger-leaved
varieties.
