Ilex aquifolium 'SIBERIA (Limsi)'

If you are looking for a hardy holly that will look like the classic hollies found in milder parts of Europe I recon that Siberia will be the right choice for you. It is a chance seedling from the Netherlands that proved hardier than common holly varieties such as “JC van Tol” or “Pyramidalis”.

Siberia is a strong grower, forming an upright, pyramidal shrub with evergreen, glossy leaves that are deep green and have irregular spines. Some leaves are entire, others have a few small spines that are not as sharp as in the English holly and do not catch clothes. Being a female plant it produces masses of red berries in autumn if pollinated by a male variety that grows nearby.

This variety is too young to know the ultimate height in full maturity but is expected to reach 3-4m in central-European climate and a bit more in zones 7 and up. Pruning in April will encourage new growths, trimming by end July is ideal for shaping. Young plants should be trimmed to achieve a good framework for dense habit.

Grow hollies in moist but well-drained, light and fertile soil. They can take periods of drought once established. Hollies do best in full sun but can also grow in shade. Before and during winter when the soil is not frozen provide good watering. Hardiness has been tested to -24°C (USDA zone 6) and is supposed to withstand yet a deeper frost.
