Aptenia cordifolia Baby Sunrose

Edward F. Gilman, Ryan W. Klein, and Gail Hansen


Introduction

Inch-long, dark green foliage and bright red, aster-like flowers combine to make baby sunrose a spectacular hanging basket or ground cover for small, exposed, well-drained gardens. Glossy foliage sparkles in the sun forming a superb backdrop displaying the 3/4-inch blossoms nearly year-round. The moderately thick, succulent stems are flexible and easily snapped. They appear to crawl along the soil and hug the ground forming a tight, almost clipped appearance. Plants grow no taller than about 3 to 4 inches.

Use and Management

More often grown in a hanging basket in well-drained media, its small stature and slow growth make it suited for a ground cover in a small landscape or rock garden. Locate it in front of an upright, grass or grass-like plant such as one of the ornamental grasses, African iris, or spartina to make a stunning, contrasting combination.

Be sure to locate baby sunrose in the full sun, and keep the soil on the dry side once it becomes established to prevent root rot. It is best suited for a coastal landscape where wind and sandy soil keep the soil dry. A light fertilization two or three times during the year should be all the plant needs to maintain a good appearance. After watering plants in containers, be sure to allow the media to become fairly dry before the next irrigation. Established landscape plants should require little if any irrigation in most years. Do not plant in a landscape soil unless it is very well-drained.

Design Considerations

The low-growing habit and small leaves of the baby sunrose cover the ground in a thick, lush layer of green, perfect for filling in among other plants in the landscape. Simple forms and light or medium green foliage of companion plants will highlight the dark green glossy foliage of the sunrose. Clumping plants with up-right form and larger textured leaves or strap-blade leaves would also contrast well with the matting, low-growing form. The mass of green works well with different flower colors, but bright and light colors will show the best next to the dark green foliage. Small- or medium-size flowers with simple forms will contrast with the small red flowers without adding too much detail.

Pests and Diseases

If soil is kept too moist, roots can rot, causing poor growth, chlorosis, and plant death.
