Landscape Attributes

Starry Eyes Nierembergia is a dense herbaceous perennial with a mounded form. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This plant will require occasional maintenance and upkeep, and should not require much pruning, except when necessary, such as to remove dieback. It is a good choice for attracting bees and butterflies to your yard. It has no significant negative characteristics.

Starry Eyes Nierembergia is recommended for the following landscape applications;

• Mass Planting
• Rock/Alpine Gardens
• General Garden Use
• Groundcover
• Container Planting
• Hanging Baskets

Planting & Growing

Starry Eyes Nierembergia will grow to be about 16 inches tall at maturity, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 3 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 should only be grown in full sunlight. 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 type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.

Starry Eyes Nierembergia is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
