One of the hardiest evergreen hollies, this is a compact pyramidal shrub with the traditional spiny blue-green foliage; doesn't produce fruit but is an ideal pollinator for Castle Spire Holly
Castle Wall® Meserve Holly has dark green foliage. The spiny oval leaves remain dark green throughout the winter. Neither the flowers nor the fruit are ornamentally significant.
Castle Wall® Meserve Holly is a dense multi-stemmed evergreen shrub with a distinctive and refined pyramidal form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.
This is a relatively low maintenance shrub, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.
Castle Wall® Meserve Holly is recommended for the following landscape applications;
- Mass Planting
- General Garden Use
- Container Planting
Planting & Growing
Castle Wall® Meserve Holly will grow to be about 8 feet tall at maturity, with a spread of 5 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 40 years or more.
This shrub does best in full sun to partial shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is very fussy about its soil conditions and must have rich, acidic soils to ensure success, and is subject to chlorosis (yellowing) of the leaves in alkaline soils. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.
Castle Wall® Meserve Holly makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
