Attractive, daisy-like bright orange flowers with golden-yellow centers mature to a lovely orange-peach as the season progresses; thrives in sandy and rocky soils and is drought tolerant.
Sweet Marmalade Tickseed is smothered in stunning orange daisy flowers with peach overtones, gold eyes and a yellow ring at the ends of the stems from mid summer to early fall. The flowers are excellent for cutting. Its ferny leaves remain emerald green in color throughout the season. The fruit is not ornamentally significant.
Sweet Marmalade Tickseed is an open 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 is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. 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.
Sweet Marmalade Tickseed is recommended for the following landscape applications;
- Mass Planting
- Rock/Alpine Gardens
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
Sweet Marmalade Tickseed will grow to be about 14 inches tall at maturity, with a spread of 20 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 8 years.
This plant should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil pH, but grows best in poor soils. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This is a selection of a native North American species. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Sweet Marmalade Tickseed is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. 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.
