Landscape Attributes

Picola Umbrella Pine 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. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any dieback. It has no significant negative characteristics.

Picola Umbrella Pine is recommended for the following landscape applications;

• Mass Planting
• Hedges/Screening
• Rock/Alpine Gardens
• General Garden Use
• Container Planting

Planting & Growing

Picola Umbrella Pine will grow to be about 4 feet tall at maturity, with a spread of 3 feet. It has a low canopy. It grows at a slow rate, and under ideal conditions can be expected to live for 60 years or more.

This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. This is a selected variety of a species not originally from North America.

Picola Umbrella Pine 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. It is even sizeable enough that it can be grown alone in a suitable container. 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.
