1 Eu­ca­lyp­tus ‘Shan­non Blue’ A hy­brid bred for the floristry trade, this vig­or­ous plant has stems of rounded, glau­cous, sil­ver leaves. It can be grown as a hedge and re­tains its colour through the win­ter. Un­pruned height 10m. RHS H5†.

2 Eu­ca­lyp­tus nicholii An airy tree with nar­row, al­most feath­ery, sage­green leaves. Its com­mon name – nar­row-leaved black pep­per­mint – ref­er­ences its strongly aro­matic fo­liage. Un­pruned height 12m. RHS H5.

3 Eu­ca­lyp­tus pul­veru­lenta ‘Baby Blue’ A com­pact, bushy cul­ti­var that can be grown in a pot. The sil­very-grey stems are long-last­ing when cut for flower ar­range­ments. Un­pruned height 5m. RHS H5.

4 Eu­ca­lyp­tus gun­nii The most widely grown species in the UK. It has peel­ing cream and brown bark, rounded, glau­cous-blue ju­ve­nile leaves and el­lip­tic or sickle-shaped, grey-green adult leaves. Sev­eral com­pact cul­ti­vars have been in­tro­duced. It grows rapidly and left un­pruned can reach 18m. AGM*. RHS H5.

5 Eu­ca­lyp­tus glaucescens ‘Tin­derry’ A vig­or­ous, bushy form with sparkling sil­very leaves and white stems. The new growth is tinged with pink. At its best when cop­piced. Un­pruned height 12m. RHS H5.

6 Eu­ca­lyp­tus ru­bida The young shoots have a cop­pery sheen over the sil­very-blue, rounded leaves. The adult leaves are glau­cous and elon­gated. Old bark flakes away to reveal a shiny white trunk. Un­pruned height 15m. RHS H5.

7 Eu­ca­lyp­tus per­rini­ana A mod­er­ately dense small tree with off-white, grey or green bark. Aro­matic, elon­gated, bluish­green young shoots pro­duce dis­tinc­tive per­fo­li­ate, ju­ve­nile leaves that even­tu­ally de­tach and spin on dried out stems. Adult fo­liage is glau­cous and lance-shaped. Um­bels of three white or cream flow­ers in sum­mer. Un­pruned height 10m. RHS H6.

8 Eu­ca­lyp­tus coc­cifera Lance­o­late, pep­per­mint-scented ju­ve­nile fo­liage on ma­roon shoots, with blue-green elon­gated adult fo­liage and mot­tled white and grey bark. Lots of small white flow­ers in the sum­mer. Un­pruned height 15m. RHS H5.

9 Eu­ca­lyp­tus archeri Smooth grey and white bark with oc­ca­sional patches of pink. Ju­ve­nile fo­liage is grey-green on purple-flushed stems. Adult fo­liage is darker. Un­pruned height 12m. RHS H5.

AD­VICE FOR GROW­ING FOR FO­LIAGE Choose the right species. Mulch, feed and water from April un­til Septem­ber. Leave to grow for two sea­son or un­til the trunk is over 5cm in di­am­e­ter at a height of 1m from the ground. Pol­lard by cut­ting trunk to around 1m in mid March and any re­main­ing branch­lets to 2.5cm. Har­vest the re­sult­ing re­growth Oc­to­ber to March. Re­peat an­nu­ally.

1 Eu­ca­lyp­tus parvula Red­dish stems on rounded ju­ve­nile leaves. Ma­ture trees have wil­low-like fo­liage and the grey bark peels to reveal a sil­very trunk. Un­pruned height 10m. AGM. RHS H5.

2 Eu­ca­lyp­tus pau­ci­flora subsp. de­beuzevillei Prized for its mar­bled white and pale-grey bark and its spread­ing habit. The leaves are larger than in most species, with a leath­ery tex­ture. Un­pruned height 10m. AGM. RHS H6.

3 Eu­ca­lyp­tus kit­so­ni­ana Wil­low-like leaves and masses of small flow­ers. Per­forms par­tic­u­larly well as a screen or hedge. Will grow in wet soils and tol­er­ates salt-laden winds. Un­pruned height 5-10m. RHS H5.

4 Eu­ca­lyp­tus urnig­era A fast-grow­ing tree with peel­ing bark that is sil­very white when young, ma­tur­ing to a ta­pes­try of grey, olive and gold. The young leaves and stems are sil­very-grey, ma­tur­ing to blue-grey. Un­pruned height 15m. RHS H5.

5 Eu­ca­lyp­tus sub­crenu­lata Smooth, grey bark with olive-green patches. When cop­piced it makes a dense hedge of small, rounded leaves that are a glossy green, oc­ca­sion­ally with a red edge. Un­pruned height 15m. RHS H4.

6 Eu­ca­lyp­tus pau­ci­flora subsp. niphophila Cream, green and grey patches of bark flake away to reveal a chalky white trunk. Usu­ally grown as a multi-stemmed tree, it has el­lip­ti­cal grey-green leaves. Un­pruned height 7m. AGM. RHS H6.

AD­VICE FOR GROW­ING FOR SCREEN­ING Se­lect the right species for your site, soil type and pur­pose. Multi-stemmed eu­ca­lyp­tus make good screen­ing trees up to 10m. Keep young trees free of grass and weeds for 1m di­am­e­ter around the base and water with ten to 15 litres of water twice a week for the tree’s first sum­mer. Feed with a gen­eral pur­pose fer­tiliser (Grafton uses Vi­tax Q4), sul­phur chips and iron.

To keep at around 6-7m, prune from an early age (from two years old) to en­cour­age bushi­ness. Keep the top of the canopy nar­rower than the base to en­sure good light lev­els reach all parts of the tree. Prune in mid March and give a light trim in June if re­quired. Never prune in win­ter.

Trees that are 10-15m will need a tree sur­geon to re­duce the crown ev­ery few years.
