Ornamental Features

Landscape Attributes

Heartleaf Geranium is a multi-stemmed evergreen shrub with an upright spreading habit of growth. 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. Trim off the flower heads after they fade and die to encourage more blooms late into the season. It has no significant negative characteristics.

Heartleaf Geranium is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use
  • Container Planting

Planting & Growing

Heartleaf Geranium will grow to be about 4 feet tall at maturity, with a spread of 4 feet. It has a low canopy. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub 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 type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America.

Heartleaf Geranium makes a fine choice for the outdoor landscape, but it is also well-suited for use 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 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.
