Height: 8 inches

Spread: 10 inches

Sunlight: full sun

Hardiness Zone: 3a

Other Names: Festuca ovina var. glauca

Description:
Heat and Drought tolerant once established, this selection produces beautiful bushy mounds of blue-gray grass-like foliage with tan colored spikes rising above in the summer; excellent performance in containers, borders and garden beds; low maintenance

Ornamental Features:
Boulder Blue Fescue is primarily valued in the garden for its interestingly mounded form. Its attractive grassy leaves remain steel blue in color throughout the year. The tan seed heads are carried on spikes from mid summer to late fall.

Landscape Attributes:
Boulder Blue Fescue is an herbaceous evergreen perennial grass 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 has no significant negative characteristics.

Boulder Blue Fescue is recommended for the following landscape applications:

- Rock/Alpine Gardens
- Border Edging
- General Garden Use
- Naturalizing And Woodland Gardens
- Container Planting

Planting & Growing:
Boulder Blue Fescue will grow to be about 8 inches tall at maturity, with a spread of 10 inches. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 8 years. As an evegreen perennial, this plant will typically keep its form and foliage year-round.

This plant should only be grown in full sunlight. It prefers to grow in average to dry locations, and dislikes excessive moisture. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. 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.

Boulder Blue Fescue 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 canvas of foliage 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.

Planting & Growing:

Butterfly Weed will grow to be about 24 inches tall at maturity extending to 32 inches tall with the flowers, with a spread of 24 inches.

Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH.
