Landscape Attributes

Califano's Dioon is a spreading evergreen perennial with a more or less rounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant, and should never be pruned except to remove any dieback, as it tends not to take pruning well. It has no significant negative characteristics.

Califano's Dioon is recommended for the following landscape applications;

• Accent
• Rock/Alpine Gardens
• General Garden Use
• Container Planting

Planting & Growing

Califano's Dioon will grow to be about 6 feet tall at maturity, with a spread of 6 feet. It has a low canopy with a typical clearance of 2 feet from the ground. It grows at a slow rate, and under ideal conditions can be expected to live for 50 years or more. As an evegreen perennial, this plant will typically keep its form and foliage year-round.

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided. This species is not originally from North America. It can be propagated by division.

Califano's Dioon is a fine choice for the garden, 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. It is even sizeable enough that it can be grown alone in a suitable container. 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, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our experts for more information on how to protect it over the winter months.
