Unlike most forsythias, this variety is grown for its low growing habit and fabulous foliage rather than the flowers; leaves are chartreuse in spring, maturing to green with white variegation

Ornamental Features

Citrus Swizzle Forsythia has creamy white-variegated forest green foliage which emerges chartreuse in spring on a plant with a mounded habit of growth. The pointy leaves turn an outstanding burgundy in the fall.

Landscape Attributes

Citrus Swizzle Forsythia is a multi-stemmed deciduous shrub with a mounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season's flowers. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Citrus Swizzle Forsythia is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Groundcover
  • Container Planting

Planting & Growing

Citrus Swizzle Forsythia will grow to be about 24 inches tall at maturity, with a spread of 24 inches. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.

This shrub should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is not particular as to soil type or pH, and is able to handle environmental salt. 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.

Citrus Swizzle Forsythia makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. It can be used either as 'filler' or as a 'thriller' in the 'spiller-thriller-filler' container combination, depending on the height and form of the other plants used in the container planting. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
