Striking, daisy-like yellow flowers with gold centers and contrasting dark burgundy ring; large 3 inch diameter flowers; tolerant of pests and drier soils, thriving in sandy and rocky soils; a smaller, more compact variety
Cosmic Eye Tickseed is smothered in stunning yellow daisy flowers with gold eyes and a burgundy ring at the ends of the stems from early summer to early fall. The flowers are excellent for cutting. Its narrow leaves remain emerald green in color throughout the season. The fruit is not ornamentally significant.
Cosmic Eye Tickseed is a dense herbaceous perennial with a mounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
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 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.
Cosmic Eye Tickseed is recommended for the following landscape applications;
- Mass Planting
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
Cosmic Eye Tickseed will grow to be about 12 inches tall at maturity, with a spread of 15 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 10 years.
This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in poor soils. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. 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.
Cosmic Eye 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.
