Life cycleIlex aquifolium 'Silver Milkboy', commonly known as Silver Milkboy Holly, begins its life cycle with seed germination, which occurs in the spring following stratification to break seed dormancy. As a seedling, it emerges with a pair of cotyledons before developing true leaves and grows slowly as it establishes a root system. The juvenile stage can last several years; during this time, the plant develops its characteristic spiny leaves, which are variegated in this cultivar, but it has not yet reached sexual maturity. Sexual maturity is typically reached after several years, and the plant starts to produce small white flowers in late spring, which are pollinated by insects to produce red berries. The berries, a key identifying feature of the holly, are often present through winter, making the plant attractive for landscaping and for wildlife. Silver Milkboy Holly can live for many decades, becoming a dense, evergreen shrub or small tree that can reach up to 15 feet in height with a spread just as wide, before eventually senescing and dying.
PropogationPropogation time
Early Spring
Propogation: The most popular method of propagating Ilex aquifolium 'Silver Milkboy', commonly known as English Holly, is through seed collection and sowing. However, due to the variegated nature of this cultivar, a more reliable method to maintain its characteristics is through semi-hardwood cuttings. This technique is often performed in late summer. Cuttings should be around 4 to 6 inches (10 to 15 centimeters) in length, and the lower leaves should be removed. A rooting hormone is applied to the cut end before it is placed in a well-draining potting mix. The pot should then be placed in a warm area with indirect sunlight and kept consistently moist until roots have developed, which takes several weeks to a few months depending on conditions.
