Landscape Attributes
Filigran Russian Sage is an herbaceous perennial with an upright spreading habit of growth. 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 cut back to the ground in late winter before active growth resumes. 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.
Filigran Russian Sage is recommended for the following landscape applications;
Planting & Growing
Filigran Russian Sage will grow to be about 3 feet tall at maturity extending to 5 feet tall with the flowers, with a spread of 3 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 30 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. 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 prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. 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, but has a definite preference for alkaline soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid.
Filigran Russian 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. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
