Description:

Feathery and soft, this variety of asparagus native to South Africa creates great visual interest when massed; flowers are short lived and are hidden behind foliage, therefore not very noticeable; the showy bright red berries each carry one seed

• Accent
• Mass Planting
• General Garden Use

Planting & Growing

Sprengeri Asparagus Fern will grow to be about 24 inches tall at maturity, with a spread of 4 feet. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 15 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant does best in partial shade to full shade. Keep it well away from hot, dry locations that receive direct afternoon sun or which get reflected sunlight, such as against the south side of a white wall. It does best in average to evenly moist conditions, but will not tolerate standing water. It may require supplemental watering during periods of drought or extended heat. 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 is a selected variety of a species not originally from North America.

Sprengeri 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.
