Ornamental Features

Alonia™ Bicolor Violet Angelonia has masses of beautiful spikes of white pea-like flowers with violet overtones rising above the foliage from late spring to late summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its small fragrant narrow leaves remain dark green in color throughout the season.

Landscape Attributes

Alonia™ Bicolor Violet Angelonia is an herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

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, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Alonia™ Bicolor Violet Angelonia is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Container Planting
  • Hanging Baskets

Planting & Growing

Alonia™ Bicolor Violet Angelonia will grow to be about 18 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 15 inches apart. 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. This plant should not require much in the way of fertilizing once established, although it may appreciate a shot of general-purpose fertilizer from time to time early in the growing season. 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. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Alonia™ Bicolor Violet Angelonia is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. 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. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
