Impatiens capensisandI. pallida
Impatiens are normally referred to as “ stir - me - nots . ”
While this nickname may conjure up icon of a spiny cactus or other uninviting species , they ’re in reality endearing , florescence annuals .
The name is infer from the way that the industrial plant disperse seed , flinging it in all direction at the little pinch .
Himalayan balsam,I. glandulifera.

Two of these touch - me - not species , cognize ordinarily as jewelweed , are wildflower that have garnered interestingness from gardeners due to their brilliant , discrete bloom .
Even though these species are typically found growing in the wild , luxuriating in fishy embankments of the forest , they can also make a lovely , born pollinator - support border planting in the garden or landscape painting .
Let ’s take a look at how to include them in your garden plan .
Here ’s what we ’ll cover :
What You’ll Learn
There are over 1,000 known species of impatiens today , withI. wallerianabeing the variety most commonly grown in gardens .
No doubt you ’ve get word these in residential and commercial landscapes , planted in colorful good deal or borders where a gardener or landscapist wanted to add low - alimony interest .
you could hear more about these inour template to develop impatiens .
You might be design to bring home the bacon the same growing stipulation as you would for these if you ’re already intimate with the conditions they require , but not so fast !
Impatiens capensis needs some somewhat unlike accommodation to thrive , principally because these species are woodland plants rather than a cultivated variety .
Let ’s bulge out by getting to lie with a little more about them .
What Is Jewelweed?
Two species of jewelweed are indigenous to North America , where they ’re typically found in gully or ditches in or bordering the timberland . They grow best in full shade with just a few hours of sunlight per 24-hour interval .
Like other impatiens , one character – I. capensis , the spot orange jewelweed – prefers a lot of water and fat , loamy soil . Unlike its cousins , this metal money enjoyswetsoil , and sometimes even standing piddle , as play off to good drainage .
The other – I. pallida , or yellow jewelweed – does n’t demand as much pee .
It ’s unclear where the common name “ jewelweed ” add up from , but the bright , colorful blossom are often adduce as possible inspiration , or the way that water droplet collect on the silvery undersurface of the leaves , glistening in the sun .
It ’s crucial to differentiate these native plants from another species that may be referred to by the same common name .
Himalayan balsam , I. glandulifera , is set apart by its violet flower . With its inception in the Himalayas , this semi - aquatic metal money is known to be invasive on several continent , including North America .
Sometimes referred to as ornamental touch-me-not or policeman ’s hat , this species is also recover in woodland areas where the stain is damp or saturate .
So , how can we tell the nativeI. capensisandI. pallidaapart from others in the same genus ? Let ’s take a closer look .
Anatomy
There are a few key visual differences between this and other form of impatiens .
Most annuals in this genus turn in a compact shape that rarely exceeds about 16 inch in top , although some can reach about 36 column inch tall at due date .
Both orangish and yellow celandine sometimes pass on these in the dust , at predominate tiptop of between two and five feet .
The most common species launch in garden , I. walleriana , has a mounded habit . Not so with these wild cousins , though , which tend to ramify into a more receptive , upright shape .
The salad days are another obvious conflict . Whereas most cultivated impatiens have flat , proportionate , and sometimes double or treble blossoms , jewelweeds have cornucopia - shaped , unmarried prime .
At the death of each trumpeted bloom for both species , there ’s a distinctive arch spine .
The lower apron of petals inI. capensistypically display a rule of orangish spots , while the relaxation of the blossom is firm orangish .
Flowers are jaundiced inI. pallidawith a modest patch of spots at the first step , though they may sometimes produce blossoms that are nearly blanched .
Interestingly , both mintage make two type of blooms . Aside from the showy trumpets thatattract pollinators , a 2nd , less conspicuous case , known ascleistogamousflowers , develops as well .
These bantam green flower do not open , as opposed to chasmogamous flowers , which do . They have no flower petal , and do n’t require pollination to bring forth viable ejaculate .
When mature , these will form seed capsules that resemble pocket-size immature beans . At the slightest touch , they ’ll burst open and widely disperse their seed .
Because of this method of self - propagation , both species self - seed prolifically , either with or without available pollinator . Each class , as the pods burst , you could be assured that your garden jewels will return in the spring .
Cultivation and History
Orange jewelweed has a prospicient account of use with indigenous peoples of North America within the plant ’s range .
The watery fluids inside the stems were used for many aim , from treating unwellness to facilitate itch and the spread of poisonous substance ivy rash .
This has led to further study and the fluid has been tested in the modern day for efficaciousness in the discourse of poison English ivy rashes .
While it has testify to be effective in aiding healing , it ’s still unclear whether this is attributed to a compound called lawsone or to saponins . Both are produced by the dotty soupcon - me - not .
blossom were , and are , used as a small-scale food informant , as they ’re comestible and make a endearing , colored improver to salads and cold veg dishes .
Both the seedpod and the cum can also be eaten , although it ’s best to run through any part of this plant in moderation as it ’s passing alimental - thick and contains calcium oxalates and Se . In some people , this combination can act as a laxative .
The shoot , foliage , and stems are also edible , although they must not be go through without cooking . It ’s urge to boil them in two alteration of weewee prior to consumption .
But , as with any dotty plant , it ’s authoritative to screen a diminished amount to make indisputable you do n’t have an adverse chemical reaction .
Pollinators particularly enjoy both the orangish and yellow species , so bees and hummingbird are often known to dart about between blossoms as they forage . Caterpillar and butterflies also rely on these plant life for support .
A host of animate being species are eff to swear on this intellectual nourishment source as well , such as deer , grouse and pheasants , and other birds , so work them into the garden can also ask round more animal as well .
Bear this in mind when add these to the garden layout to avoid invite likely defoliator that might also like to nosh on your other crops .
Propagation
As I note previously , jewelweed really does n’t call for any help from us to ego - propagate . It ’ll readily reseed itself wherever it ’s planted , and those ejaculate will sprout as long as environmental precondition are favorable .
However , if you ’d prefer to start seeds indoors to transfer to new locating , that ’s easy too !
If you ’re take off from source , you ’ll most belike need to compile some from a furious source , since the seeds must stay moist to be feasible .
convey a paper or shaping bagful with you and determine a plant that has acquire semen pod – these can usually be found between tardy summertime and mid - fall .
Be certain to only amass seed from areas where this is tolerate . start the bagful and hold it as stuffy to the seed pods as potential .
A docile touch is all it takes for the seed pods to burst open , and you ’ll only need a few , depending on the routine of specimens you intend to propagate . Once the seeded player are collected , do not wait more than a few hr to swear out them as described below .
It ’s best to start seeds outdoors if possible , to admit them to sprout on their own when conditions are appropriate . If you begin source indoors , the seedlings should n’t be moved outside until after the last rime particular date for your area has go along .
From Seed
Seeds that have been collected will necessitate a period of two to three calendar month of cold social stratification . This can be reach indoors or alfresco .
Fill a resealable plastic sandwich bag withpeat mossand dampen it lightly . Add the seeded player and seal the base , then rank it in the icebox until about six weeks before the last frost date in your realm .
You could also skip this measure if you have a suitable expanse in your pace or garden to simply scatter the ejaculate on the soil surface .
Just give the flat coat a light raking to roughen it a bit first . The seeds call for light to germinate , so do n’t use more than a thin level of soil to cover them .
Seeds should be sow alfresco in the winter to allow them to cold stratify naturally .
If you ’re planning to use four - inch pots or acell tray for generation , prepare your container with copious , loamy filth . One part pot soil orcoconut coirto one part compost work well .
Fill the cubicle nearly to the brim , drizzle the substrate well , and make indisputable any excess water run out off . set one to two seeds per cell , leave behind them on the surface . you may use a light sprinkle of sand to hold them in place , if desired .
Be sure to check the moisture stage every daylight . If the seeds dry out out , they will not bourgeon . Give them a lightsome nebuliser of water daily to keep them moist .
While you’re able to keep the tray indoors and they ’ll spud at room temperature , you could also move it outdoors to a spot where it will meet collateral sunlight for a few hour per day , if weather condition permits .
set out outdoors also facilitate the pauperization for hardening off the seedlings afterwards .
Indoors , place the tray near a generator of collateral sun . It can take six to eight weeks , or sometimes more , for germination to take spot . Once they sprout , you ’ll need to move them out of doors to their permanent locating as soon as possible .
Be certain to harden off seedlings started indoors by step by step disclose them to the outdoors a few hours at a time , until they ’re to the full acclimated .
From Seedlings/Transplanting
Whether you ’ve found startle available for purchase or propagated them from cum , you ’ll eventually involve to transplant your seedling to their lasting outdoor location . I ’ll cover the idealistic growing site in a bit more detail in the next section .
After seedlings have been hardened off , train a mess as deep and wide as each planting cellular phone or hatful .
cautiously turn each out of its pot and home one in each yap . Even matured specimens have fairly weak stems , so do n’t deal them roughly . Gently contract the soil to tauten it in piazza , and body of water in well to settle .
Space the works about 18 to 24 inch apart and avert letting the soil dry out for best results .
How to Grow
These specie are native to a broad range throughout North America , and as such , they can be come up growing throughoutUSDA Hardiness Zones3 to 10 .
And as I ’ve mentioned , both orange and yellow jewelweed prefer timberland develop precondition rather than a intemperately prepared plot .
work these metal money in the garden requires prefer a spot where they ’ll be in full or fond specter , with dry land that remain moist most of the time . The yellow character can allow slimly less wet .
If you ’ve got a eyepatch uncommitted near a tree diagram line , current , or pond where the Sunday is dappled , that would be idealistic . If not , planting near tree diagram or George Herbert Walker Bush that cast shadow for most of the daytime would be the next best thing .
After your seedlings or starting signal have been moved to their home for the season , keep them systematically watered . If your region experiences mediocre or above intermediate rainfall , you may not need to add auxiliary water .
In drier areas , you might be watering one to two times per week , reckon on your soil and the temperatures you ’re experience .
Bear in mind that this is an yearly that will self - seed in the fall , so be prepared to offer enough blank space between the plants and other landscaping so they ’re not compete for resource – these specie are known to be rather aggressive challenger !
They can also become quite large , so be sure to allow adequate way for up to five ft of height and a two- to three - metrical unit counterpane .
Wildflowers do n’t broadly need much in the way of plant food if their pauperism are being met at the planting site . It ’s important to localise them in a worthy emplacement to keep them in adept health .
substratum at the site should be loamy and rich with organic cloth . Amend land that is miss ahead of plant by glance over in two to three inches of compost , older manure , or both .
Down to Earth Rose and Flower Mix
Any plant food you might opt to use should be downhearted in atomic number 7 to foreclose excessive foliage increment at the expense of get bloom , such as this DTE Rose and Flower Mix with a 4 - 8 - 4 NPK ratio that’savailable from Arbico Organics .
Growing Tips
Maintenance
Pruning jewelweed is not recommended . Doing so can reduce the identification number of bloom of youth it produce .
render wraith , equal wet , and enough elbow room for these specimens to spread are the chief concerns .
At the end of the time of year , after the semen have been mould upon the undercoat , it ’s best to leave the internet site undisturbed . If you must cut back dead or dying cloth , do so carefully to avoid stepping on the seeds as much as potential .
If you ’d opt not to allow them to self - sow , be sure to clip off faded bloom , or consider wrapping the entire specimen with a muslin or linen drawstring travelling bag to forestall seminal fluid from being disperse if you ’d favor to deliver them .
Wrapping should be done toward the death of the season to avoid inhibiting pollinator access , but before the seeds mature and scatter .
Any escapee that stock the following spring can be dug out and replanted elsewhere , given away , or plucked and added to thecompost pile .

Managing Pests and Disease
Just as with most wildflowers , there are very few concerns for these species from insects or animals , as well as disease pathogen .
Herbivores
As I antecedently advert , cervid are the primary defoliator for this species . Ifdeer are a business concern in your area , you may want to tot up a few additional plants to your garden to scrap losses , or tolerate seed to spread course at the terminal of the season .
Birds and rodents might graze sporadically , but they generally prefer the come to the foliage .
If you ’re worried that may inhibit increment from self - seeding , you may always accumulate the seeds and stack away them in cold social stratification through the winter .
Insects
There are only a few louse that will disturb jewelweed . Some of these , such as caterpillars , need the plants as important food sources and will rarely use up enough to kill the host .
A specific species ofaphid , Macrosiphum impatientis , or the jewelweed aphid , is be intimate to colonise along the stems . Just as with many other types of aphids , they ’re tiny and green .
Because the stems are not very hardy , it can be unmanageable to ensure these pests . usually , you could smash them or spray them away with a blast of water system from the hosiery , but not in this case .
Spraying with neem oil or insecticidal Georgia home boy is your best wager , although these should be used as slenderly as possible to keep off causing damage to pollinator .
Another common pest , Schizomyia impatientis , or the jewelweed midge , produces gall in develop buds .
Affected bud can range in color from pale green to nigh over-embellished , and the midge lay their eggs on the internal and organise colony . As they mature , the adults will winter inside the galls , and emerge in the spring .
Galls should be removed and destroy on sight to prevent further facing pages of these pests .
Disease
Most impatiens suffer from ailments from prison term to fourth dimension , such as downy mildew . I. capensis , however , is an extremely repellent specie that rarely falls victim to disease .
In fact , only rust cause byPuccinia reconditafungi is common enough to mention , and usually resolves itself in time . It seldom bear upon bloom and is n’t known to propagate enough to lay waste to a point of view .
Signs of rust are spots that appear on leaves with a red , orange , or chicken colouration . part of the foliage and stems may become contorted or puff a turn .
take down that rusting can spread to some grasses and shrubs , so if you ’re interested about neighboring specimens , you may use scissors hold to cut out impact cloth and cast away it in a sealed trash dish .
Best Uses
Borders and mass plantings along a wood sharpness , current , or pond are the good ways to add jewelweed to your garden or landscape painting .
If you have some boggy priming coat , these are the perfect option to use up some of that extra H2O and contribute some beautiful flower !
Pair these species withferns , bourtree , and other shade- and moisture - loving coinage .
Planting in or near the garden will line pollinators , so they can also visit your crop .
If you ’re abeekeeper , they also make an splendid foraging source when plant at an adequate aloofness from your bee box .
