It is best known in our houseplant index for its low maintenance and fast growth. This tree will likely liven up your house (or garden) with its blue-green colored leaves. But, only if you learn how to take proper care of it for it to thrive.

Fortunately, this is exactly what we’ll cover in this Silver Dollar Tree Care Guide. So let’s dive in.

The fundamental caring guidelines for every Silver Dollar Tree can be summed up into the following:

Scientific / Botanical Aspects

In botanical terms, the Silver Dollar Tree belongs to the Myrtaceae family, the genus Eucalyptus and the species Cinerea, hence its scientific (or botanical) name Eucalyptus Cinerea (you-ka-LIP-tus sin-e-RE-a).

As with other Eucalyptus’s, the Silver Dollar Tree is an evergreen plant, which means it will be present year round in your garden.

The Silver Dollar Tree is a plant native to Australia. This is why the Eucalyptus Cinerea is used to growing in specific regions of Australia.

You might be wondering why your Silver Dollar Tree’s native region is important. Well, if you know where your plant originally came from, you’ll know which environment conditions it prefers, and with it, knowledge on how to replicate it at home.

With this in mind, the Eucalyptus Cinerea will be most used to regions where the plant hardiness level falls between 8b, 9a, 9b, 10a, 10b, 11b, 11a and the ideal climate zone is between 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, H1, H2.

As a rule of thumb, you should remember to keep your Silver Dollar Tree in soil with moist but well-draining to well draining characteristics, as these will guarantee the right conditions for your plant to grow and thrive. 

When you consider this, this is why you should aim to choose soil that has good drainage properties to keep the right moisture levels at all times. 

However, in our experience, the best solution to knowing the right amount of water for your Silver Dollar Tree is with the ‘thumb’ technique. Basically, you insert your finger into the soil, and based if you feel the soil moist or dry, you determine if it needs any water, which is the most appropriate way to go about watering your leafy friend.

Soil Mix

As mentioned earlier, the Silver Dollar Tree prefers to have soil with good drainage properties at all times, reason why you need to make the soil mix out of sand and loam.

In addition to this, expert gardeners recommend having preferably neutral to acid soil.

Light and Exposure

In terms of light & exposure, the Silver Dollar Tree requires full sun in order for it to thrive under the right conditions. 

Most experts agree that this tree will do well as long as you keep it in full sun, and it will be able to grow properly.

Specifically, we recommend that you place your Eucalyptus Cinerea in full and direct sun (more than 6 hours of direct sunlight per day).


Being an evergreen plant, the Silver Dollar Tree will be present year round in your garden.

But, you can expect it to have its ‘prime-time’ during the spring (early, mid, late), the summer (early, mid, late), the fall, and during the winter.


The Silver Dollar Tree produces some beautiful white, or gold/yellow and white flowers around this time of year.


The leaves from the Silver Dollar Tree have a beautiful blue-green color during most of the year.

In particular, they have a simple arrangement with a alternate and opposite organization in its leaves.

You can expect the leaves from your Eucalyptus Cinerea to be around (1-3 inches) in size.
