Gardeners who are dealing with watering restrictions and on-going drouth are wise to view aboriginal species such as purple salvia as substitutes for thirsty , exotic ornamentals .
Natives tend to be better adapted to local weather extreme and grime conditions , as well as having long - place upright relationships with local fauna , making them less prostrate to disease and pest problem , and ask less maintenance overall than many non - native species .
As a native species of the American West , purple salvia is an fantabulous option for gardener in this neighborhood who wish to cultivate a downcast - maintenance evergreen shrub .
We ’re going to underwrite every step of develop this works in the landscape painting – here ’s a flying overview of what ’s on the visible horizon :
What You’ll Learn
What Is Purple Sage?
Purple sage is an evergreen plant woody bush or shrublet that is highly adapt to arid climates .
Classified botanically asSalvia dorrii , this mintage produces bicolored flowers in late spring to early summertime .
Inflorescences are bundle at the last of theme , and bear fragrant blue heyday with purple bracts . Like the efflorescence ofpeasandorchids , these showy flowers are bilaterally proportionate .
Blooms are held out from an upright , rounded , or spreading mound of foliage on separate and sometimes spinous stems .
Purple sage foliage is fragrant and ranges from greenish gray to blue to silver in color . This plant ’s silverish foliage reflects the hottest light-colored wavelengths , avail to keep the works cool and concentrate piss loss .
This shrub has diametrical parting that are oval to lance form , and often folded inward .
It can survive low temperatures plump down to about -20 ° atomic number 9 , and can be turn inUSDA Hardiness Zones5 to 9 .
S. dorriishares the unwashed name “ imperial sage ” with another member of theSalviagenus , S. leucophylla .
This other salvia ’s native range is limited to coastal southerly California .
S. leucophyllacan get much larger than the subject field of this article , and while it ’s also a waterwise alternative , it is n’t quite as well - adapted to uttermost xeric conditions .
Cultivation and History
purplish salvia is native to the westerly United States , include Arizona , California , Idaho , Nevada , Oregon , Utah , and Washington .
Found in the waterless regions of this part of the nation , this metal money with its royal hued blooms often grow among sagebrush population in pinyon juniper forest , chaparral , scabland , or cool desert shrubland .
Thismember of the mint family , or Lamiaceae , is related to such culinary favorites asbasilandmint . Within its genus , Salvia , it ’s tight related to another herb , broadleaf sage , as well as the low water landscaping favourite , Russian salvia .
Purple sage is sometimes called “ desert sage , ” “ Dorr sage , ” “ gray ball sage , ” or “ tobacco sage . ”
This arid clime species has a wide history of ethnobotanical uses .
Among its numerous medicinal uses , it has been used by the Northern Paiute as a cold remedy , the Shoshoni for treat upset stomachs , and by the Kawaiisu to relieve worry .
In plus to its reputation as a medicinal works , S. dorriiachieved more widespread name recognition when it was conspicuously feature in a 1912 Western novel by Zane Grey , entitled , “ Riders of the Purple Sage . ”
Propagation
Desert salvia can be circularize via seed or cutting . We ’ll discourse the unconscious process for both of these methods as well as covering how to transplant potted specimen .
From Seed
This case of salvia has better sprouting rates after a period of cold , moist social stratification , so these seeds should be sown directly in the dip , or in the spring after chilling in the electric refrigerator .
For spring sowings , post desert sage seeds in moist sand and store in the refrigerator for six workweek prior to planting .
When you are quick to sow , prepare the planting area by removing any weeds .
Ultimately , these plants need two to three human foot of space , so plant groups of seeds two to three feet apart , and a quarter to half an inch deep .
imbed several seeded player for each plant you ’d like to have , to make up for potentially pathetic sprouting pace . you’re able to always slim down seedlings later .
water supply thinly , proceed the ground moist until they germinate .
If more ejaculate have germinated than you necessitate , fragile seedling to one plant every two to three groundwork .
As untried specimen get make , they willrequire more waterthan fledged plant – irrigate them every other mean solar day if there ’s no rainfall . During hot conditions , weewee daily .
Gradually taper off watering as young specimens become established .
From Cuttings
Experts atThe Royal Horticultural Societyrecommend propagating this species of salvia via semi - ripe cutting – that ’s to say , thinning in which the base of the stem is hard while the tip is still subdued .
These cuttings should be taken in autumn .
Take a clipping that is four to six inches long , making certain to select a theme that looks healthy and is free from any signs of plague or disease .
will at least four leaves attach at the tip of the newspaper clipping , and remove the balance from the bottom half nigher to the cut oddment .
Dip the base of the cut in clone gel , then insert it into a four - inch nursery kitty take with growing medium .
Olivia ’s Cloning Gel
you could purchase Olivia ’s Cloning Gel in an compartmentalisation of sizesfrom Arbico Organics .
Be sure to choose a growing medium that has fantabulous drainage and is scummy in organic matter , such as those designed for cacti and succulents , like Sun Gro ’s Black Gold cactus mix .
It’savailable on Amazonin eight - quart bag .
Place the pot cutting in agreenhouse , or cover the smoke with a plastic bag and locate it where it will be exposed to indirect sunlight throughout the day .
H2O lightly , keep the growing medium slightly moist until it has root – this may take a few months . Once the cutting has rooted , remove the plastic base .
While ground specimens are cold hardy , these rooted cuttings will need to acclimatise before they are able-bodied to tolerate wintertime weather , so wait until all hazard of frost has fall out in spring to graft them .
From Transplants
You may like to apply agarden journalto adumbrate out a design for your landscaping project before you get started . Whether you adumbrate out the point of your plantings beforehand of fourth dimension or not , allow two to three feet of space between plants .
Prepare to transfer your desert sage by digging a gob that is about double the breadth of its glasshouse pot and a few inches deeper .
If you are in a particularly arid region , you’re able to help the transplant survive utmost climatic condition by planting it in a low “ volcanic crater . ”
That stand for your industrial plant will sit at a slightly lower level than the surrounding soil , in a depressive disorder that can catch and hold water as it go off from the high-pitched surround soil .
Once the hole is quick , remove the transplant from its pot , and loosen up the border of its source ball with the thenar of your hand .
Take some of the soil you removed from the mess , crumble it up , and place it back in the bottom of the trap . Next , fix the specimen in the hole .
If you are using the volcanic crater technique , the crown of the plant should be about an inch or so lower than ground floor .
Now backfill with the stain you removed , but take care not to spread over the crown of the plant with soil . The goal is to catch piss around the plant , not to half inhume it in soil .
Water in the organ transplant . Until it becomes established , it will need water more frequently , so if the rain clouds are n’t doing the task for you , provide irrigation as need .
For me , in my mood where I get roughly seven inches of water per class , I irrigate freshly transplanted specimens every twenty-four hour period for about the first month , then gradually decrease from there .
How to Grow
Purple sage should be grown in areas where it can prosper in the desiccated conditions it is well - adapted to . If you live in a more humid expanse , I recommend choosing atype of salviathat is more altered to your mood !
This species of salvia want full Sunday and does best when grow in fast drain grunge with a pH range between 6.0 and 7.8 .
uprise this plant in soil eccentric similar to what would be set up in its aboriginal home ground – soils that are low in organic matter and include limestone , sand , and disintegrate granite .
Desert sage is a xeric works that can go with as small as 3.7 inch of rainfall per yearonce established , but in some area of its native range , this works might have as much as 35 in of rain per year .
This mintage should require no irrigation once shew .
Growing Tips
Pruning and Maintenance
Like most other native industrial plant , when grown in appropriate surround , desert sage will be a low criminal maintenance selection for your garden .
S. dorriiwill not ask fertilizing since it ’s well adapted to lean desert soils .
As formulch , employ only rock or gravel , since mulches such as leaf compost or pine bark contain too much organic matter , will raise ambient humidness , and may potentially do fungal problem .
Mulching with rock ‘n’ roll or crushed rock will provide protection from both heat and cold , as well as slowing down encroaching weeds .
As for pruning , these flowers do n’t ask to bedeadheaded , as their wither blooms can bring a certain knockout of their own .
Plus , the seeds of purple salvia will supply a fete for various chick populations , including chickadees , grossbeak , jays , and sparrows .
Specimens ofS. dorriioften uprise into a dead round pile that looks not bad and tidy . However , if you end up with one that has other plans , you could use a pair ofgarden snipsto shape it up a bit as postulate .

gardener are most likely to encounter disease problems related to overwatering , which can allow fungal disease such ascrown rotorroot rotto gain a foothold .
To prevent these diseases , grow purplish salvia in well - draining filth and water the surface of the soil rather than the top of the works .
It ’s also of import to grow this species in well - adapt environments , debar organic mulches such as bark or folio bedding material , and go easy on the irrigation .
