FLOWERING SHRUBS
Almost
every garden needs some flowering shrubs. They give the garden depth,
structure, shelter, privacy, and ground cover to smother weeds and save on
maintenance. Some are evergreen, some have variegation and many flower, often
with fantastic scent. Most are very easy to grow and types can be found to suit
full sun, shade, dry soils, moist soils, acid soils, alkaline soils and some such
as Escallonia, Rosemary, Broom, Choisya and Senecio can tolerate exposure to
maritime conditions.
However
when choosing garden shrubs we tend to buy in plants we really like then hope
we can create conditions that they are happy to thrive in.
Rhododendrons
and camellias were very high on my list, with R. praecox and Elizabeth
essential plus camellias Donation (pink) and Adolphe Audusson (red) but
remember these need acidic moist peaty soils that is free draining and do not
mind some shade. Coming down in size the dwarf evergreen Japanese Azaleas come
in a wide range of colours and are great for ground cover. Deciduous Azaleas
will grow a lot taller but can be brilliantly coloured and scented.
Other
shrubs like moist, but not waterlogged soil include Amelanchier, Viburnums,
Spiraea and for really shaded spots try the Hypericums and Mahonia.
Dry sandy
soils are not a problem with the right selection so include Cytisus brooms,
Genista gorses, Senecio, Cistus, Ceanothus and Kerria.
Shrubs
with scented flowers are numerous but some of the best would include
Philadelphus, Viburnums, Choisya, Daphne, Osmanthus, Lilacs and many shrub
roses.
Sometimes
we like to try out the more tender plants just in case climate change works in
our favour. This has worked well over the last ten years or so till we got hit
by the one off serious winter two years ago. That was when hardiness got put to
the test and most of us lost prize specimens. My beautiful Leptospermum Red
Damask never survived as well as my six year old mature date palm, but my
mature Eucalyptus was unaffected. The Australian palm, Cordyline and all my
outdoor hardy fuchsias got cut back to ground level, but all came back again by
mid summer.
Gardeners
have plenty patience, but sometimes this gets put to the test. Way back in the
late sixties when I was sitting my Diploma practical exams at the RHS gardens
in Wisley I came across this gorgeous Cornus kousa chinensis. I never forgot
its name and put it on my must have list for the future. I bought one eight
years ago, but am still waiting to see the first flowers. The nursery had grown
them from seed rather than grafting them. I am now informed that it can take
fifteen years for this plant to reach a mature enough condition before it
starts to flower. I have pruned the stems, root pruned it, threaten it
frequently, but no amount of bad language seems to be working. It just loves to
grow with great vigour, but if no flowers appear this spring it is in serious
trouble.
Planting
Shrubs
are likely to last a long time so make sure the soil is in good shape suited to
the type of shrub to be planted. Prior to planting make sure there are no
perennial weeds and dig over borders incorporating compost to improve the soil.
The best time for planting is in the dormant season, but late spring is ok as
long as the bushes can get watered if dry weather prevails. Water plants before
and after planting and most shrubs will benefit from a dressing of fertiliser,
except rhododendrons and azaleas which may get scorched leaves. All shrubs
benefit from a compost mulch to help retain moisture and prevent weeds growing.
Give plants enough space according to how big they are likely to grow and any
resultant bare soil in the early years can be sown down to annual flowers.
Plant of the week
Saxifrages come in many forms and flower colours. London
Pride is one of the more common, but well known types. Most are cushion forming
hugging the ground in solid clumps that slowly enlarge. The foliage forms
clusters of tight rosettes and flowers form in early spring to mid summer. They
prefer well drained gritty soil on the alkaline side, in rock gardens or beside
stone walls and path edges. They are very hardy and snow and frost will not
harm the plants or flowers.
Painting of the month
Lemon Narcissi is one of my spring flower images
painted boldly in acrylic on large box canvases. This project also included
tulips, Iceland poppies and flag iris. All of the flowers were grown in my
garden and allotment in City Road which gives me plenty of ideas for flower
paintings. The allotments and my garden will feature in my outdoor art workshop
running the first week in July but painting is also planned at Broughty Ferry,
Rait village and Magdalen Green beside the bandstand with views of the Tay
Bridge.
