What You’ll Learn
What Is Blue Ginger?
To start , Dichorisandra thyrsiflorashares the common name “ blue powdered ginger ” withAlpinia galanga , also sleep with asgalangal .
Though these plants share a resemblance , to some degree , in terms of ontogenesis drug abuse and form , they are unrelated .
D. thyrsiflorais not a extremity of the pep or Zingiberaceae family , nor is it eatable . It is really part of the Commelinaceae family , alongside various species of dayflower andspiderworts .
Native to southeastern Brazil and considerably cultivated in USDA Hardiness Zones 9 to 12 , blue ginger produces violet gloomy flower in clusters up to eight inches long , with each individual flower being up to three - quarters of an in across-the-board .
The prime are fertilized viabuzz pollenation , i.e. when bee land on bloom and rapidly vibrate their chest , inveigle the release of pollen . When pollinated , these flush finally get seeds within strike orangish berries .
Underneath these striking blooms are shiny , lance - shaped , deep dark-green leaves that acquire up to a foot retentive and two inches wide .
The leave go forth with sheathed bases in a fashion like tored ficus , and are alternately arranged in a spiral around the cane - like stems , almost like a staircase .
As clump - imprint plants , private gloomy peppiness specimens utilise their rhizomatous etymon system to build colonies , which can lead to pretty significant tidy sum ofD. thyrsiflorain time .
When discussing dismal pep , it ’s important to differentiateD. thyrsiflorafrom its stuffy relativeD.pendula , akaweepingblue gingerroot .
The difference is right there in the name : standard blue ginger originate pretty upright , whereas weeping dreary gingerroot modernise a cascading habit with matureness .
Additionally , D. thyrsiflorablossoms over a six- to eight - week - retentive period in the summer and fall , whileD. pendulablooms sporadically year - round .
Cultivation and History
To understand aristocratic gingerroot ’s horticultural origin story , we want to wrap the clock back to the Austrian excursion to Brazil , financed by the Austrian Empire , which took place from 1817 to 1835 .
Fourteen experienced naturalists were recruited for the outing , admit Johann Christian Mikan , a natural history professor at the University of Prague and an accomplished plant scientist .
As the expedition team worked its manner through Brazil , Professor Mikan happen upon and describedD. thyrsiflorafor the first metre .
The genus nameDichorisandraalludes to the double anther of the flower , whilethyrsiflorareferences the way the blooms grow on stave - like stems .
In 1822 , a blue ginger specimen grown in the United Kingdom was documented by Sir William Macarthur in his catalogueHortus Camdenesis . Its popularity in polish continue to grow and spread in the subsequent one C .
Later , D. thyrsifloraearned the sought after Award of Garden Merit from the Royal Horticultural Society in 2012 . Across the pond in the United States , low ginger was selected as Plant of the Year by the Florida Nursery Growers and Landscape Association in 2008 .
To this day , D. thyrsifloraremains a beloved summation to residential and commercial gardens , both indoors and out .
Propagation
You have a handful of selection for propagating puritanic ginger : planting abeyant rootstock , settle stem cuttings , division , or transplanting .
From Rhizomes
Planting dormant rootstalk is a passably dewy-eyed process , whether in the primer coat or in a container .
After soaking the rhizomes in pee for a few hours , bury them an in or two abstruse in the soil or potting mix set horizontally , with any node manoeuvre upwards .
Rhizomes can be plant in individual pots , or spaced about 18 to 36 in aside in the garden .
Water in to settle , and and keep the grunge moist as young outgrowth egress and matures .
From Stem Cuttings
To glean cuttings from a matured plant , pick out the healthiest - looking stems in spring or summer . With a sterilized blade , tailor directly below a guest .

Defoliate the bottom half of each cutting , then inundate it by half in water to encourage base development .
The container that you choose for this can be anything , really . Mason jars , psychometric test subway system , even marvellous double pellet eyeglasses – whatever you have on hired man .
Place the containers in a bright , indirectly lit expanse indoors .
Once their newly - organize solution exceed two inches in duration , the slip are ready to go into three - inch pile fill with a 50 - 50 admixture of sphagnum peat moss and perlite .
verify the muckle have drainage holes ! Bury the source while hold back the foliage above the land line and water them in .
prefer a localization where the rooted cuttings will receive bright , collateral luminosity somewhere in your home , and keep the growing medium moist .
After a calendar month of this treatment , stay to care for the cutting just like you would mature blue peppiness specimens if you destine to keep them indoors .
For those interested in outside polish , you ’ll need to harden off the cuttings before transplant them as trace below .
In early spring – once nighttime temperatures remain above 55 ° F – leave the pots alfresco in partial nicety for 30 to 60 minutes .
Each subsequent day , increase the exposure sentence by an additional 30 to 60 moment until they can withstand an entire day ’s picture out of doors . At this point , it ’s time to transpose !
Via Division
As glorious as a bunch of blue powdered ginger is , you may want to subdue its size a bit at some point .
Or perhaps you wish to start another colony somewhere else in your garden . Whatever the reasonableness , division is a fantastic way of acquiring moreD. thyrsiflorafor yourself … or a booster !
pluck a day in springtime or summertime for dividing , and irrigate the to - be - separate plant life deeply 24 hours beforehand .
Come partitioning time , turn over a circle around the perimeter of the flora , doing your best to keep the shallow rhizomatous root system intact .
nobble the plant out and set it on a tarp or newspaper so you’re able to keep your divisions organized and the surround area sporting .
Gently tease the root system free of any soil that ’s hang on so you’re able to see what you ’re working with .
With a sharp and sterile blade , separate the plant into as - sized daughter plant . The amount here depends on your destination and how expectant the female parent flora is , but four divisions is a nice , orotund figure to shoot for .
Hopefully , you ’ve been conglomerate any brush - off soil on your tarpaulin – it ’ll make out in handy for satiate in those transplant holes . Speaking of …

Make certain the transplantation site or your intended indoor location is posit in a smear where it will receive fond ghost or collateral light .
Dig a hole that ’s as deep as and somewhat panoptic than the transplant ’s radical system . get down the plant in , backfill the golf hole , and piddle in the transplant . Keep the spiritualist around the transplant moist .
How to Grow
In some respects , juicy pep is tougher than it take care – it can handle humid conditions , brief full stop of drouth , and being root - bound .
But in other ways , D. thyrsifloracan be a bit namby - pamby .
irrespective , right cultivation goes a longsighted way in keeping this flora healthy and happy .
Climate and Exposure Needs

Indoor growth want lustrous yet collateral light , a minimum temperature of 60 ° atomic number 9 , and plenty of humidity . The latter can be increase by grouping works together or placing a humidifier nearby .

Adding a couple in of mulch will do wonders for maintaining soil moisture and suppressing weeds . constitutional wood chips and leaf bedding material are both satisfying options .
For container planting , repotting should be done on an “ as - absolutely - necessary ” basis .
This plant can tolerate root bindage , but once say roots start poking out the drain holes in the bottom of the container , you ’ll want to repot .
