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

Planting & Growing

Merole's Dioon will grow to be about 6 feet tall at maturity, with a spread of 7 feet. It has a low canopy with a typical clearance of 1 foot from the ground. It grows at a slow rate, and under ideal conditions can be expected to live to a ripe old age of 300 years or more; think of this as a heritage perennial for future generations! As an evegreen perennial, this plant will typically keep its form and foliage year-round. This is a dioecious species, meaning that individual plants are either male or female. Only the females will produce fruit, and a male variety of the same species is required nearby as a pollinator.

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 sandy 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, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets..

Merole'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, this plant may be too tender to survive the winter if left outdoors in a container. Contact our experts for more information on how to protect it over the winter months.
