Silver dollar eucalyptus (Eucalyptus cinerea) is an evergreen Australian native tree grown for its round, silvery-blue juvenile leaves and fast growth. It suits sunny Sydney gardens with space, or a large pot while it is young, but it becomes a big tree if you leave it unpruned.
This guide covers how big it gets, where to plant it, how to care for it, how to keep it in a pot, pruning rules and Sydney costs. You will also see what to check with council before cutting anything large.
Key points
- Mature height and spread vary with the tree, so treat any figure as indicative and check the nursery tag before you plant.
- It wants full sun and well-drained soil, and it dislikes wet feet in heavy Sydney clay.
- Maintenance is low once established, but large trees need an arborist and may need council approval before you prune or remove them.
- Eucalyptus foliage is commonly listed as toxic to pets, so keep dogs and cats from chewing it and call your vet if they do.

Silver eucalyptus names and lookalikes
Sellers use several names, and some silver-leaved gums are sold under the same label, so check the botanical name on the tag.
| Name you see | What it usually means | Check |
|---|---|---|
| Silver eucalyptus, eucalyptus silver | A general term for silver-leaved gums | Ask for the botanical name. |
| Silver eucalyptus tree | Usually the full-size tree form | Ask about expected mature size. |
| Dollar gum tree | A common name for round-leaved silver gums | Confirm the species before buying. |
| Eucalyptus cinerea tree, argyle apple | The species most often sold as silver dollar | Look for the Eucalyptus cinerea label. |
| Silver dollar eucalptus | A common misspelling of the same plant | Search both spellings at nurseries. |

Full grown silver dollar eucalyptus tree size
- Expect a tree that can reach well above a single-storey roof, with a height range of roughly 6 to 15 m (indicative — check the plant label).
- Allow for a broad, open canopy, which can spread several metres each side (indicative — check the plant label).
- Plant it well away from the house, fences and power lines, because the tree gets bigger than most buyers expect.
- Keep it clear of sewer and stormwater pipes, since eucalypt roots seek out moisture.
- Give it a trunk’s width of mulch-free space at the base to avoid collar rot.
- Check overhead lines and neighbours’ boundaries before planting anything that will grow above head height.
Where to plant silver dollar eucalyptus in Sydney
- Choose the sunniest spot in the yard, because shade makes the tree leggy and dulls the silver colour.
- Pick a raised or sloping position in heavy clay suburbs such as western Sydney so water drains away.
- Plant it in sandy coastal soil with a good mulch layer, and shelter young trees from salt-laden wind.
- Leave generous space from paths, driveways and pools, since fallen leaves and bark create mess.
- Avoid planting under power lines, and book a licensed electrician or arborist for any work near wires.
- Check your council’s tree rules first, because larger trees and listed species often need approval to prune or remove.
How to plant a young eucalyptus
- Water the pot or tube thoroughly and let it drain before you take the plant out.
- Dig a hole about as deep as the root ball and wider than the pot, without breaking up the base of the hole.
- Tease out circling roots gently, because tight roots keep strangling the trunk for years.
- Set the plant so the top of the root ball sits level with the soil.
- Backfill with the original soil and firm it lightly without stomping.
- Water slowly and deeply, then mulch around the tree but keep mulch clear of the trunk.
- Stake only if the plant cannot stand in wind, and remove the stake after the tree is steady.
Potted silver dollar eucalyptus tree
| Task | How |
|---|---|
| Pot choice | Use a large pot with drainage holes and a heavy base, since the tree grows top-heavy. |
| Potting mix | Use a quality native or premium potting mix with good drainage, not heavy garden soil. |
| Position | Place it in full sun, off wet decks and away from balcony edges in strong wind. |
| Watering | Water deeply when the top of the mix is dry, and follow Sydney Water’s Water Wise Guidelines by watering before 10 am or after 4 pm. |
| Repotting | Move up a pot size when roots circle the base, usually in spring or early autumn. |
| Long term | Plan to plant it out in the ground, or prune it regularly to keep it compact. |
Caring for silver dollar eucalyptus
| Task | When | How |
|---|---|---|
| Watering | Weekly in the first summer, then only in dry spells | Soak slowly at the base instead of sprinkling the leaves, and never leave a hose running unattended. |
| Feeding | Spring | Use a native-friendly slow-release fertiliser exactly as the label directs. |
| Mulching | Autumn or spring | Spread mulch out to the drip line and keep it off the trunk. |
| Shaping | Late winter to early spring | Remove dead and crossing branches while the tree is small enough to reach from the ground. |
| Pest watch | Summer | If you see chewed or damaged leaves, see a pest controller for diagnosis. |
| Pets | All year | Keep leaves and prunings away from dogs and cats. |
Pruning silver dollar eucalyptus
- Prune young trees yourself only if you can reach every cut safely from the ground with sharp, clean secateurs or loppers.
- Cut back by hard pruning in late winter if you want the round juvenile foliage, but do this while the tree is small.
- Leave large limbs, work above head height and anything near power lines to a qualified arborist.
- Check your council’s tree preservation rules before cutting a large tree, since fines can apply for unapproved work.
- Wear eye protection, gloves and closed shoes, and never use a chainsaw above shoulder height.
- Run powered tools within the NSW hours: from 7 am on weekdays and Saturdays and from 8 am on Sundays and public holidays.
Common silver eucalyptus problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Yellow or dropping leaves | Waterlogged soil or a dry spell | Improve drainage and water deeply in dry weather. |
| Leggy, sparse growth | Too much shade | Move a potted tree, or thin nearby plants. |
| Dull green leaves | Maturing foliage as the tree ages | Prune while young if you want to keep juvenile leaves. |
| Dead branches | Drought stress or old age | Remove small branches yourself and call an arborist for large ones. |
| Lifting paving or cracked pipes | Roots chasing moisture | Book a licensed plumber or arborist for assessment. |
| Chewed or spotted leaves | Insects or disease | See a pest controller and your local nursery for advice. |

FAQ: silver eucalyptus trees
How big is a full grown silver dollar eucalyptus tree?
A full grown tree is a medium to large eucalypt that can reach well above a house roofline. Treat any height as indicative and check the nursery tag, because size varies between plants. Plant it with plenty of space and keep it away from pipes and power lines.
Can you grow a silver dollar eucalyptus in a pot?
Yes, for a few seasons. Use a large pot, a good drainage mix and a sunny spot, then water deeply when the top is dry. Because it grows quickly, plan to plant it out in the ground or prune it regularly to keep it compact.
Is silver dollar eucalyptus the same as eucalyptus cinerea?
The tree usually sold as silver dollar is Eucalyptus cinerea, also called argyle apple. Other silver-leaved eucalypts can be sold under the same name, so read the botanical name on the plant tag. If you are unsure, ask the nursery before you buy.
Is silver dollar eucalyptus toxic to pets?
Eucalyptus is commonly listed as toxic to dogs and cats, and owners report drooling, vomiting and lethargy after chewing it. Keep pets away from leaves and prunings. If you think a pet has eaten any, contact your vet or the Animal Poisons Helpline.
