Botanical Name: Eucalyptus gunnii x gunnii 'France Bleu'®
Common Name: French Blue
Status: Evergreen Multi-stem Tree
Origin: Gunnii from Tasmania, but this variety is a selection from Renault Nurseries (France)
Why we like this variety:-
- Slow growing for a Eucalyptus
- Intense, beautiful, silvery blue foliage - fabulous
- Very bushy habit
- Highly prunable
- Great for growing in a pot.
- Very small and compact. Perfect for any garden, patio or balcony!
Description, habit, uses and attributes: This tree is grown as a multi-stem. Chacterised by beautiful, small silvery-green leaves. Blue-ish juvenile leaves with a purple tint, red-brown juvenile branches. Keep it pruned to encourage a dense, bushy habit and encourage silvery growth.
Lignotuber: yes, so will regenerate off the stump. Responds well to coppicing, pollarding and cutting with secateurs and shears.
How to use in the landscape and/or garden:-
- Good structural shrub for the wider landscape and also for the smaller garden where you require a smaller bushier evergreen shrub. E. 'France Bleu'® will look fabulous in a mixed border, bringing cool silvery blue to the planting scheme. An excellent structural evergreen multistem small tree or trimmed shrub for the winter garden.
- Floral Art: can be used domestically for cut foliage if allowed to grow large enough, but I suspect it is not vigorous enough for commercial production.
- Hedges Screens: would look great planted as a hedge/screen. Most likely suited to a low hedge, a bit like lavender. If allowed to grow, its dense habit will make a great privacy screen and the silvery blue foliage will reflect light, making it difficult to see beyond the screen. Prune in spring, with 2-3 dry days forecast, to an 'A' shape, to keep it bushy down to the ground. Avoid pruning Eucs during wet weather, to discourage fungal attack.
- Pot Culture outdoors: Eucalyptus 'France Bleu' ® is an excellent subject for terrace pots and large planters or raised beds as it is small and compact. See our notes on growing Eucs in pots for compost, feeding etc.
Shoots 'n Leaves: Silvery-blue with a tint of purple, become more green-blue with age. Obovate; elongated, small, oval leaf shape, almost rectangular.
Flowers: fragrant white flowers followed by gum nuts.
Leaf Aroma: typical strong Eucalyptus fragrance
Rate of Growth: slow for a Eucalyptus. In the nursery, they have grown about 20cm (8 inches) over 4 months, so will possibly grow 60-90cm (2-3ft) in an average year. We will update this page as we gather data from our nursery trials.
Height in maturity, if left unpruned: Current estimates are that E. gunnii 'France Bleu'® will reach 3m (9ft) tall by about 3m wide in the medium term. Maybe taller in exceptional growing conditions, but still less than half the finished height of its parents. Remember, E. gunnii 'France Bleu'® is a versatile, much bushier tree than straight E. gunnii; reminiscent of a Pittosporum in habit and can be kept trimmed to form a small multi-stem tree or a bushy 'shrub-on-a-stick' for the smaller garden.
Hardiness: in the region of -10 to -15°C
Planting Position and Soil Preference: Enjoys and needs full sun for compact bushy growth. E. 'France Bleu'® will grow in a wide range of soil types from moisture retentive clays (but not waterlogged), deep fertile loams to free-draining stoney ground; any soil pH of alkaline, neutral and acidic persuasion. Follow our planting instructions (issued with each order) for the best results. Water with 1-2 gallons of water per week for 8 weeks after planting (from March to September), depending on the weather.
Make life easier for you and your new tree: Plant with the mycorrhizal fungi product Rootgrow. Eucalyptus in particular have a special, lifelong relationship with their root fungi, the latter of which actively transport food and water directly into the tree roots, helping your new Euc establish faster and more efficiently, particularly in challenging types of soil.
