QUERCUS ILEX (ACORN)

Description

This large spreading evergreen tree bears dark green leaves which are tough and leathery, with pale undersides. Finally becoming a large and impressive specimen, it is native to the Mediterranean region, although it grows well in almost all parts of the UK once established. The male flowers are catkins and the female flowers give rise to large seeds or "acorns", in a very similar way to the English Oak, Quercus robur. Seeds are rarely produced, and only in "Mast" years which occur with oaks only every five to ten years, hence their scarcity. It takes one of its common names from 'holm', an ancient name for holly (whose botanical name is Ilex).

Sowing Advice

These seeds may need a further period of stratification to break their dormancy. Soak for 24 hours then place them in a sealed freezer bag in the fridge keeping them moist for a week or two. The seeds can then be sown and should germinate normally in a safe, bright, cold place outdoors, but can take up to 6 months or even longer so do not discard the seed pot. Alternatively sow the seed in a moist seed tray and leave outside over the winter to allow for natural stratification to occur.
