Holly tree?

I bought this cheaply YS (£3.00) from Morries a while ago and the label says its a holly tree?

The leaves are black and it isn't as spiky as the hollies I see in the woods. I thought the colouration may have been because it was a young plant? but young hollies in the woods are green and spiky!
I love its colouration as it is so hopefully it won't grow into a boring green holly!

Ilex x meserveae 'Gentle'


Sometimes referred to as a Blue Holly, this is a slow growing evergreen that reaches up to sixty centimetres in height.
This plant has small waxy densely packed leaves which are a blue green colour from spring to autumn. New shoots tend to be red during the growing season and leaves turn a burgundy purple colour for the autumn, adding some gorgeous colour to your garden at different points in the year. Produces an abundance of white flowers in spring.
This plant requires a rich fertile soil that is free draining but is tolerant of most soil types. It grows in either a sunny position or partial shade and is happy in all aspects.
This plant grows well as low hedge and looks good in drifts, planted in a mixed border. If you have no garden then this plant will grow in a container on a balcony quite happily, keep the soil moist and feed with a feed well in spring and early summer.
High quality pot grown plants in 2- 3 litre containers.
