I. grandulosa (see I.orientalis) comprises a group of medium to large clump-forming perenials, with woolly buds and turning to large daisy like orange-yellow flowers with many narrow ray flowers 3-5 inches across around a central disk. They prefer full sun, well drained soil and are cold hardy. Moisture needs vary depending upon species. Propagate by seed, or by dividing in spring or fall.

Plant Care



Fertilizing
How-to : Fertilization for Annuals and Perennials

Annuals and perennials may be fertilized using: 1.water-soluble, quick release fertilizers; 2. temperature controlled slow-release fertilizers; or 3. organic fertilizers such as fish emulsion. Water soluble fertilizers are generally used every two weeks during the growing season or per label instructions. Controlled, slow-release fertilizers are worked into the soil ususally only once during the growing season or per label directions. For organic fertilizers such as fish emulsion, follow label directions as they may vary per product.

Light
Conditions : Full Sun

Full Sun is defined as exposure to more than 6 hours of continuous, direct sun per day.

Watering
Conditions : Normal Watering for Outdoor Plants

Normal watering means that soil should be kept evenly moist and watered regularly, as conditions require. Most plants like 1 inch of water a week during the growing season, but take care not to over water. The first two years after a plant is installed, regular watering is important for establishment. The first year is critical. It is better to water once a week and water deeply, than to water frequently for a few minutes.

Planting
Problems
Miscellaneous
Glossary : Border Plant

A border plant is one which looks especially nice when used next to other plants in a border. Borders are different from hedges in that they are not clipped. Borders are loose and billowy, often dotted with deciduous flowering shrubs. For best effect, mass smaller plants in groups of 3, 5, 7, or 9. Larger plants may stand alone, or if room permits, group several layers of plants for a dramatic impact. Borders are nice because they define property lines and can screen out bad views and offer seasonal color. Many gardeners use the border to add year round color and interest to the garden.

Glossary : Herbaceous

Herbaceous refers to a non-woody plant that dies back at the end of its growing season, generally after frost or during the fall of the year. The rootstock of perennials will overwinter, providing the plant is hardy in that area, and resume growth in the spring.

Glossary : Perennial

Perennial: traditionally a non-woody plant that lives for two or more growing seasons.
