Majestic Cork Bark Oak Bonsai Tree (Quercus suber) | 18-Year-Old Evergreen in Large Emerald Green Pot
This exceptional 18-year-old Cork Bark Oak Bonsai (Quercus suber) is a truly commanding outdoor bonsai with presence, power and extraordinary natural character. It stands tall with a strong informal upright design, showcasing a thick, muscular trunk that rises confidently before tapering into expressive, beautifully arranged branches. The movement is bold yet refined, and the whole tree radiates age, strength and artistic drama.
Recently repotted by Lloyd into a brand-new bright emerald green glazed ceramic bonsai pot, the tree looks phenomenal. The bright green glaze enhances the deep green evergreen foliage while also highlighting the warm tones and texture of the bark. The pot suits the design perfectly, grounding the tree and giving the whole composition a mature, stately feel.
This is the exact bonsai you will receive.
A Species Full of Character & Heritage
The Cork Bark Oak is one of the most iconic Mediterranean evergreen oaks. Loved for its deeply fissured, thick, corky bark. On this specimen this deep texture is just starting to develop. The species naturally develops dramatic bark texture early in life. As the tree matures, the bark becomes more rugged and sculptural, giving the bonsai an ancient woodland appearance that few species can match.

Does a Cork Bark Oak Flower?
Yes.
Quercus suber produces very small flowers in spring:
-
Male flowers: Long yellow catkins that hang in clusters.
-
Female flowers: Tiny and hard to spot, found near the leaf axils.
They are wind-pollinated, so the flowers are not showy or scented.
Does a Cork Bark Oak Bonsai Produce Acorns?
Yes.
When pollinated successfully, the female flowers develop into acorns, which:
-
Start off green
-
Ripen to brown in late summer to autumn
-
Sit in a distinctive, scaly acorn cup
The acorns are typical of oak trees and are loved by birds and wildlife.
Additional Notes
-
A cork oak does not need warm Mediterranean conditions to fruit — it can still produce acorns in the UK when mature enough.
-
In bonsai form, flowering and fruiting is possible, but more common on older, strong trees and may depend on the season and growing conditions.
