A dense, bushy variety with stunning spikes of long lasting sky blue flowers; somewhat drought tolerant; excellent for the sunny border or containers
Crystal Blue Sage has masses of beautiful spikes of sky blue flowers rising above the foliage from mid spring to mid fall, which are most effective when planted in groupings. The flowers are excellent for cutting. Its fragrant narrow leaves remain grayish green in color throughout the season. The fruit is not ornamentally significant.
Crystal Blue Sage is an herbaceous perennial with an upright spreading habit of growth. 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 and hummingbirds 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.
Crystal Blue Sage is recommended for the following landscape applications;
Planting & Growing
Crystal Blue Sage will grow to be about 16 inches tall at maturity, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 20 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years.
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 not particular as to soil type or pH. It is somewhat tolerant of urban pollution. 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.
Crystal Blue Sage is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
