Silver Dollar Eucalyptus (Eucalyptus cinerea) ‘Silver Dollar Tree’ is an evergreen and strikingly decorative plant, primarily valued for its distinctive bluish-gray, silver-toned leaves. This plant exhibits very rapid growth, reaching a height of 24–35 inches (60–90 cm) in its first year under favorable conditions. Due to its dense canopy and long branches, it is an indispensable choice for floral arrangements, where eucalyptus stems are utilized both fresh in bouquets and dried in long-lasting compositions.
In the Estonian climate, eucalyptus is typically cultivated as an annual ornamental plant in garden beds or as a longer-term patio and indoor plant in pots. Its compact growth makes it perfectly suited for smaller gardens and balconies. During warm periods, the plant thrives outdoors, but as temperatures drop, the pot must be moved indoors for wintering. It is crucial to note safety: all parts of the plant are poisonous if ingested, rendering it unsuitable for consumption.
Usage and Cultivation Instructions:
-
Sowing Time: Begin growing plants indoors in March or April.
-
Location: Prefers a sunny to lightly semi-shaded location. The soil must be well-drained and rather dry – the plant does not tolerate standing water.
-
Sowing Depth: Sow seeds on the surface of moist seed-starting mix and cover with only a very thin layer of soil or sand (seeds require light for germination). Keep the sowing moist and warm.
-
Transplanting and Spacing: Plant young plants outdoors in garden beds or spacious pots only after the last spring frosts (from the second half of May until July). Maintain a spacing of approximately 16 x 20 inches (40 x 50 cm) between plants.
-
Pruning and Harvesting: Branches for floral arrangements are predominantly collected from August to October.
Tips and recommendations:
-
To dry branches, cut them on a dry day, tie them into small bunches, and hang them upside down in a dry, shaded, and well-ventilated room. This method helps the leaves retain their shape and characteristic color.
-
If you wish to grow eucalyptus as a perennial, bring the pot indoors to a bright and cool room (approximately +41 to +50 °F / +5 to +10 °C) for wintering before autumn temperatures drop below freezing. Water the plant very sparingly in winter, avoiding complete drying out of the soil.
-
Ensure that the pot or planting area is located where small children and pets (dogs, cats) cannot access and chew on the poisonous leaves.
