Koeleria glauca
Grey-blue koeleria (Koeleria glauca) is a cool-season grass native to North America. It is a vigorous, clump-forming grass that has an open spike-like inflorescence. It is often used as an ornamental species, popular in meadows and rock gardens. Grey-blue koeleria is drought and salt tolerant and grows well in poor soil. Its fine-textured, blue-green foliage is often the highlight of gardens in late spring and early summer. It is an excellent choice for naturalizing or as part of a native conservation project.

watering
Water grey-blue koeleria (Koeleria glauca) regularly and thoroughly. During the growing season water the plant deeply about once a week, making sure the entire root system is moist. During periods of extreme heat, more frequent and/or longer watering sessions may be necessary. Once established, the grey-blue koeleria is quite drought tolerant, however, so don't overwater. During the fall and winter months, water much less, allowing the soil to dry out between watering sessions.
sunlight
Grey-blue Koeleria (Koeleria glauca) likes full sun exposure to produce the best growth and flowering potential. For optimal results, the plant should receive at least 6 hours of direct sunlight per day, preferably 8 to 12 hours of daily sun. During the summer months, early morning and late afternoon sunlight is best to avoid the heat of the mid-day sun. To supplement their direct sunlight needs, Grey-blue Koeleria can benefit from indirect sunlight and/or bright, indoor artificial light.
pruning
Grey-blue koeleria should be lightly pruned every spring, right after the new growth has developed. Start by removing any dead or weak stems, as well as any crossed or broken branches. You can also prune away any shoots that are not in the ideal shape or form. This type of grass generally does not need to be pruned more than once a year.
