The Strawberry Tree and Other Great Slow Growing Plants

The Strawberry Tree and Other Great Slow Growing Plants


One of the great things about being a gardener is that you never stop learning. Walking round a local park recently, (I live and work in central Israel) I came across a splendid old Strawberry tree, Arbutus unedo, and immediately wondered why I had neglected even to consider it for the private gardens I build.

The principle reason can probably be traced to a reluctance, exacerbated no doubt by commercial pressures, to include some slow growing plants in the garden design. This bowing to the demand for quick results at any cost, leads us, professional and home gardener alike, to frequently prefer unsuitable but Fast growing species, to slow growing ones that would be the best choice for a given situation. What after all is more important - how the garden looks 3 months after being built, or how it looks and feels five years later?

The Strawberry tree from Southern Europe is an ideal speciMen for a Mediterranean and mild winter garden. It is evergreen, growing slowly to about 8-9 Meters. It has an interesting sculptural form, becoming twisted and gnarled in maturity, and a uniquely beautiful peeling bark, revealing a reddish-brown trunk. Arbutus is one of those rare plants where the fruit and flowers appear simultaneously. Both are decorative, although the fruit while edible is not to everyone's taste!

There are in fact a number of advanTAGes in growing slow growing trees over Fast ones. The primary one being that they are much easier to shape and train in the early years than many rampantly growing trees. Slow growing plants are typical to dry climates, while fast growing ones typically grow in tropical and sub-tropical regions. Clearly as the scarcity or abundance of water is a major factor determining the rate of growth of a particular species, it follows that slow growing plants are generally more suited to a water conserving regime than fast growing plants.

The pine is another example to take note of. In Israel the rapidly growing Aleppo pine, Pinus halepensis, was the preferred choice in both parks and forestation projects. Unfortunately, its susceptibility to pests and disease has made it a rather regrettable choice. Nowadays the slow growing Stone pine, P. pinea is being used to far better long term effect. Let's not forget also the importance to a Mediterranean garden of the Olive tree and slow growing species of oak, as here one can see the correlation between slow growth and longevity.

With regards to landscape hedges, slow growing bushes like Carissa and Privet, are easier to keep in shape than those that grow rampantly like Bougainvillea or Clerodendron. Slower growth means less trimming, shearing and general maintenance. As for bushes and shrubs for use as informal hedges and screens, it can be a shame to give up on plants like Pittosporum, Myrtle, Pistacia and Nandina, just because they take a few years to fill in.
