Looking for a plant that can withstand harsh weather and form a dense shelter? Look no further than Ilex aquifolium, also known as European Holly or Christmas Holly. Native to parts of Europe, Africa, and Asia, this evergreen tree or shrub is known for its spiny, shiny, dark green leaves; fragrant white flowers in May; quarter-inch red fruit; and adaptability to different conditions. It is an excellent hedge plant, tolerating hard clipping and maritime exposure. It can grow up to 30 ft tall, but is often smaller, making it a popular ornamental shrub or hedge. The glossy green prickly leaves and bright red berries, produced only by the female plant, have long been associated with Christmas and are a subject of music and folklore. It is also a pioneer species that repopulates the margins of forests or clearcuts. However, it is important to note that the plant is considered a noxious weed in California and is invasive in certain areas. So, if you're looking for a beautiful and hardy plant, Ilex aquifolium may just be the one for you!
