Asparagus Fern is primarily grown for its highly ornamental fruit. It features an abundance of magnificent red berries in late summer. Its attractive tiny needle-like leaves remain light green in color throughout the season. The flowers are not ornamentally significant.

This is a high maintenance plant that will require regular care and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. It has no significant negative characteristics.

Planting & Growing
Asparagus Fern will grow to be about 30 inches tall at maturity, with a spread of 4 feet. Although it's not a true annual, this plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.
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, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This species is not originally from North America.
Asparagus Fern is a fine choice for the garden, but it is also a good selection for planting 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 growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
