The glossy narrow leaves are highly ornamental and remain burgundy throughout the winter. The fruit is not ornamentally significant.

Landscape Attributes

After Dark® Agonis is a dense multi-stemmed evergreen tree with a shapely form and gracefully arching branches. 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 tree, and usually looks its best without pruning, although it will tolerate pruning. It has no significant negative characteristics.

After Dark® Agonis is recommended for the following landscape applications;

  • Accent
  • Hedges/Screening
  • General Garden Use
  • Container Planting

Planting & Growing

After Dark® Agonis will grow to be about 25 feet tall at maturity, with a spread of 15 feet. It has a low canopy with a typical clearance of 3 feet from the ground, 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 tree should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America.

After Dark® Agonis is a fine choice for the yard, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used 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. Be aware that in our climate, this plant may be too tender to survive the winter if left outdoors in a container. Contact our store for more information on how to protect it over the winter months.
