Eucalyptus seeds from around the world.
2389 Baby Blue Floral Variety Eucalyptus pulverulenta
This variety bred especially for professional cutflower
production. Grows 15-25 feet tall and hardy for zones 7 and
TRM519 Silver Dollar Eucalyptus cineria
Grow for its decorative or herbal quantities, UltraClean seeds for easy germination. Native to Australia, argyle apple or silver dollar tree is a broadleaf evergreen tree that will grow as a single trunk tree to 25-60' tall in its native habitat. Bark is reddish-brown, peeling on smaller stems. If grown as an annual shrub from seed, it typically grows rapidly to 6-8' tall by mid-summer. Juvenile foliage consists of opposite rounded silvery bluish-green leaves (to 2" long) resembling large coins, hence the common name of silver dollar tree. Foliage is aromatic. Small white flowers rarely appear on juvenile trees or container plants. Foliage stems are frequently used by florists in fresh flower arrangements. Hardy for zones 8-11.
D7945 Citrodora Eucalyptus ( Eucalyptus citrodora )
Commonly known as Lemon Bush. This aromatic plant starts easily from seed. When grown in a container, it only reaches 3 to 4 feet tall. No matter where you live, you can grow this lovely plant from seed in your own home and enjoy the fresh lemony fragrance. Its fresh and lemony aroma is uplifting and simply brushing the leaves will release more fragrance that will remind you of the citronella candles sold to repel mosquitos. Outside in warm zones, it will grow into a small tree, but is most commonly grown as a container plant in cooler zones. It produces sword-shaped gray-green leaves, tiny white blooms, and a bit of red fall foliage change. For growing indoors, find a nice container and grow from seed in a bright window. It can also be grown outdoors, but bring it in before the first frost to winter it indoors.
Oil from the leaves is applied to the skin as a medicine and insect repellent. Citrodora Ecalyptus oil is used for preventing mosquito and deer tick bites. It is also an ingredient in chest rubs used to relieve congestion. The oil has a strong fresh citronella-like odor with a sweet balsamic undertone. Very effective insect repellent due to a higher citronellal content than citronella ( which is commercially harvested from citronella grass, a different type of plant and is used in many insect repellants ).
Eucalyptus Citriodora has good branching and makes an attractive container plant with wonderful citrus-spice fragrance. It is actually an herb, and its 3-inch leaves are bold and dramatic indoors, and the white summer blooms add another interesting dimension to this versatile plant.
The plants are winter hardy in USDA zones 8-11, but can be grown as a container plant or annual in any zone.
Trees bloom in winter in outside in warm zones, in the greenhouse they bloom in late winter to early spring. The white blooms are not very distinctive. The blooms are followed by woody urn-shaped capsules about 3/8 of an inch wide.
Eucalyptus citriodora need full sun with a well-drained soil mix for container growing. Most gum trees grow in very nutrient poor soils and fertilizer is not needed; however container plants should be feed once during the spring. To control the size of the trees in containers, do all pruning and repotting in late to early spring after flowering.
How to start seeds and grow:
Start seed indoors into a starter tray. ( We like to leave seed packet in the fridge for 30 days before sowing, this seems to enhance the germination ). Press the seed into the soil and cover lightly, about twice the thickness of the seed. Keep the seeds moist by watering from underneath. Once the seedlings are 4 to 5 inches tall, transplant into containers. Start with a 1 to 2 gallon container with potting mix and after a year or so, transplant into a larger 3 to 5 gallon container. Feed monthly during the growing season with water soluable plant food or mix granular 5-10-10 fertilizer with micronutrients into the soil each year.
TRM162 Apple Box Gum Eucalyptus bridgesiana
A contorted tree to 50' from Australia whose wood and crushed foilage has the smell of ripe apples. For a variation on the 'rounded juvenile leaves' theme seen in eucalyptus, try this species, which has alternate, rather than opposite, juvenile leaves that are heart-shaped rather than round. Besides having potential as a foliage plant, it also makes an attractive tree with a contorted habit, long pendulous leaves and rather showy white flowers in late summer.
This species is popular in the Southeast for its ability to thrive in hot, humid conditions and grow back very vigorously if it freezes to the ground. It has also been successful in the desert climate of Las Cruces, New Mexico. It seems to be hardy to about 10 - 15 °F.
A handsome, long-lived sturdy tree, this eventually 100' tall tree flowers profusely and is excellent for honey production, as well as being ornamental with its glossy lance-shaped leaves.
2298 Blue Gum Eucalyptus gunnii
The Blue Gum forms a striking specimen with branches of rounded
leaves in clearest blue. Making a handsome tree or bush,
Eucalyptus gunnii is the ideal plant to add style and flair to
your garden with its shimmering charm. Eucalyptus gunnii is
hardy in cooler regions once the plants are established.
However, it is best to provide a warm, sheltered position and
give winter protection over the first 2-3 years. Height 10-25m
(32-80ft) Zones 8-10.

SF063 Rainbow Eucalyptus ( Eucalyptus deglupta )
Eucalyptus Deglupta is a tall tree, commonly known as the "rainbow eucalyptus", Mindanao Gum, or Rainbow Gum. The unique multi-hued bark is the most distinctive feature of the tree, it is considered to have the most colorful bark of any tree in the world. Patches of outer bark are shed annually at different times, showing a bright green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones.
Grown mostly in tropical settings. Winter hardy to USDA Zones 10-11 where this tree will grow well in rich, medium to wet soils in full sun. Intolerant of frost.
FB150 Rose Gum Eucalyptus Grandis
Rose gum is a tall tree with smooth bark, rough at the base fibrous or flaky, grey to grey-brown. At maturity, it is often 100 feet tall, though the largest specimens can exceed 150 feet tall.
Leaves are stalked, lanceolate to broad lanceolate, glossy dark green. White flowers appear in mid autumn to late winter . E. grandis is found on coastal areas and sub-coastal ranges from Newcastle in New South Wales northwards to west of Daintree in Queensland, mainly on flat land and lower slopes.
The bark is thin and deciduous, shedding in strips to expose a smooth surface marked with flowing patterns of silvery white, slaty gray, terra cotta, or light green. Occasionally a "stocking" of light-gray, platelike or fissured bark persists over the basal I to 2 m (3 to 6 ft) on the trunk.
Rose gum is one of the most important commercial eucalypts, with more than one-half million hectares (1.3 million acres) planted in tropical and subtropical areas on four continents. Massive planting programs have been carried out in the Republic of South Africa and Brazil, and there are substantial plantings in Angola, Argentina, India, Uruguay, Zaire, Zambia, and Zimbabwe. In southwest Florida rose gum may be an emerging commercial species for plantations. It has been successfully tested for pulpwood and fuel; and its wood has potential for poles, pallets, veneer, and other products. In California, Hawaii, and Puerto Rico, rose gum appears in some species trials and landscaping. Cold hardy to about 32 degrees.
FB151 Snow Gum Eucalyptus alba
Grows to 30-50 feet tall with a spreading canopy.
The attraction is the bark which is powdery white but salmon pink when the old bark is shed. It has ovate leaves and creamy white flowers appearing in May to September
This is a useful, ornamental tree in Australia and warmer parts of the USA. Hardy to zone 8.
FB152 Tasmanian Blue Gum Eucalyptus Globulus
The Tasmanian Blue Gum, Southern Blue Gum or Blue Gum, (Eucalyptus globulus) is an evergreen tree, one of the most widely cultivated trees native to Australia. They typically grow from 30 to 55 m (98 to 180 ft) tall.
The bark shreds often, peeling in large strips. The broad juvenile leaves are borne in opposite pairs on square stems. They are about 6 to 15 cm long and covered with a blue-grey, waxy bloom, which is the origin of the common name "blue gum". The mature leaves are narrow, sickle-shaped and dark shining green.
Blue gum is one of the most extensively planted eucalypts. Its rapid growth and adaptability to a range of conditions is responsible for its popularity.
The leaves are steam distilled to extract eucalyptus oil. E.globulus is the primary source of global eucalyptus oil production, with China being the largest commercial producer. The oil has therapeutic, perfumery, flavoring, antimicrobial and biopesticide properties.
Eucalyptus Seed Germination Instructions (
Note: Please print these instructions for future use, seed
packets do not include detailed germination instructions as size of packet label is limited ).
Seed germination of Eucalyptus generally
falls within two categories: Those that need no pre-treatment
and those that need chilling or cold stratification. Only those
species that come from colder areas need the cold
stratification process. Seed sourced from warmer climate areas
do not need to be pre-chilled.
About 95% of Eucalyptus seed needs no
pre-treatment. Species of the "snow gum" and a few other
species found in colder areas provide a better germination rate
when they have been cold stratified. Those Eucalyptus species
we have found to respond to cold stratification are:
Amygdalina, coccifera, dalrympleana, debeuzevillei,
delegatensis, dives, elata, fastigata, glaucescens, goniocalyx,
kybeanensis, mitchellana, niphophila, nitens, pauciflora,
perriniana, regnans, stellulata.
Cold stratification of seed is a simple
process. Using a filler like perlite, vermiculite or sand, take
2-3 times the volume of filler per volume of seed. If you are
stratifying 1 teaspoon of seed, use 2-3 teaspoons of filler.
Mix together and slightly dampen and place in the zip lock bag
the seeds arrived in and date. Place this in the refrigerated
section of your refrigerator - not your freezer! Generally 4-6
weeks of chilling is sufficient, although we have not shown any
detriment to the seed by leaving it in for longer
After the stratification process is
complete you can sow the seed at your convenience.
Don't try to separate the seed from the inert material, sow all
Instructions for seed sowing: Eucalyptus
seed is generally sold with chaff (inert material). Sow both
seed and chaff on the surface of a pre-moistened media. Use a
high quality seed starting mix that is not clumpy or full of
bark, a premium seed starting mix is well worth the investment.
Some prefer to create their own special perlite/sand mix, this
does very well also.
Note, it is rumored that soaking seeds in
Hydrogen Peroxcide will increase germination, we do not do
this, but it seems to be a common practice with many
Sow the seed (and chaff if so mixed) on
the surface of my pre-moistened perlite/sand mix. Cover the
seed no more than 1/16" with sand and then cover with
Ideal germination conditions are around 68-72 degrees F with a
humidity of near 100%, but you will still get good results at
lower humidity levels. Average germination time is about 2
weeks, although some species will germinate faster and others
at a much slower rate, some taking 6-12 weeks.
Once germination has taken place,
ideally, you should remove the container of seedlings and place
it an an area of bright light and provide a lower temperature
of 55-60 degrees F for several weeks. The lower temperature
provides a stockier seedling. Higher temperatures tend to make
seedlings stretch and they become weak and spindly.
Ideally, pick out the seedlings at the
"true-leaf" stage for transplant. The "true-leaf" stage is not
the same as the cotyledon leaves. When a seed germinates,
generally 2 leaves will show - these are the cotyledon leaves.
Additional growing time is needed for the "true-leaves" to
Once the seedlings are at the "true-leaf"
stage, carefully pick out the seedlings and transplant into
individual cells. Hold the seedlings by the leaves, not the
stem to prevent damage to the main stem. Carefully water the
seedlings in and monitor media moisture. You don't want them
soggy wet nor too dry, a slightly moist balance is what the
seedlings need. Grow on in pots for the first year.
