Russian Sage
Common Names: Russian Sage
Latin Name: Perovskia atriplicifolia
General Info
- Falls over and gets leggy if not in full sun, so may need staking or support.
Can be controlled somewhat by pinching young shoots or by providing a
strong-standing accompaniment that the plant can drape itself around for
support.
- From the steppe, pakistan, afghanistan, central asia.
- Flowers June through October, though I thought we flowered even earlier.
Should flower for 2-3 months.
- Organic mulch probably not great here. Gravel better bc it allows moisture to evaporate.
- To prevent flopping grow shorter varieties, stake or cage your plants or
pinch back the growing tips when the plant is 1 foot tall. Divide plants
every 3 to 4 years to encourage better flowering. Dig up the whole clump of
Russian sage in spring; divide it into wedge-sized pieces and replant in a
location with similar growing conditions.
Soil Requirements
- They don't really care. Everything is fine, just not too wet. Wide range of acceptable pH.
Water Requirements
- very drought tolerant, hates too much water. Don't even worry about watering this one after it is established.
- Only water after periods of extended drought.
Fertilization
- Like too much water, too much fertilizer really messes this guy up.
- Scatter a handful of general-purpose fertilizer or a shovelful of compost
around each plant every other year in late fall.
- Russian sage does not generally require fertilizer to flourish, even in
sandy, rocky or alkaline soils. If your gardening routine involves spreading
compost and mulch, add no more than 1 inch of the material around Russian
sage in the spring as the new growth begins to appear.
Pruning
- Should be cut back almost to the ground before growth begins in spring since
flowers only on new growth. Plants trimmed to 15–61 cm (5.9–24.0 in) in early
spring provide the best subsequent growth and flowering.
- Spring and summer care for Russian sage consists mainly of pruning. When new
spring growth emerges, cut the old stems back to just above the lowest set of
leaves. If the plant begins to spread open or sprawl in late spring or
summer, shear off the top one-third of the stems to encourage upright growth.
Remove the top half of the stems if the plant stops blooming in summer. This
encourages new growth and a fresh flush of flowers.
- When the plant is in full flower, you may extend the blooming season and
discourage stems from bending over by snipping off the small side branches
that have faded, spent blossoms.
- Well-established Russian sage may send out underground stems that emerge as
tender, green shoots near the plant's base. These new starts are welcome when
Russian sage is used in a mass planting or for a divider hedge, but if neat,
tidy clumps are preferred, the shoots need to be removed. Gently scrape the
soil away from stem leading back to the main plant and sever it with the
sharp edge of a trowel. Dig up the separated shoot and discard it, or place
it in a container with rich potting soil to grow for placement elsewhere.
- Deadhead spent flowers to encourage
more blooming into fall.
Seasonal View
Spring
- Cut down to almost the ground if did not do it in winter.
- Fertilize just a bit if you like.
- Prune as described above.
Summer
- Should start flowering
- Prune as described above.
