Superbells®‘Blue’
I love adding coloring to my garden , but plants like petunias are a bit too much for me with their Brobdingnagian , gaudy flowers . Calibrachoa does pretty much the same problem , but with – I think – a little more discreetness .
What I love most about calibrachoas is their trailing riding habit . you’re able to put them into the bound of a container , and they will spill over the side .
Or , you could put them under taller plant and they will sprawl out , track the undercoat with lots of little flower . This helps to keep weeds under control condition while looking super precious .
While calibrachoas are comfortable to produce , you must ensure the circumstance are right-hand for them . Here is a dewy-eyed usher on how to get the practiced out of these fun little plants .
What You’ll Learn
What Is Calibrachoa?
Calibrachoas are also bed as Million Bells ® or Super Bells ® . These are their trademarked names in the horticultural industry . “ Million bells ” is also often seen in common usage .
They resemble minipetuniasand , like their with child counterparts , originate from Brazil . They ’re members of the Solanum family , or the nightshades , the same family astomatoesandpeppers .
Million bells have humble , funnel shape - forge flowers that are around half an inch across . The leaves are small , oval - shaped , and sticky , like genus Petunia leaves .
Calibrachoa has a drop back habit and is often refer to as a “ spiller ” for its ability to spill over the side of a container orraised layer . It ’s a brilliant summation to pots and hanging baskets and good enjoyed when allowed to trail .
Although calibrachoa is a short - lived perennial in warm climates such as those of USDA zona 9 to 11 , these plants are grown as annuals in most other places . Unfortunately , they are not cold-blooded - tolerant , so they usually postulate to be toss out at the end of the time of year .
Cultivation and History
Unlike most garden prime that have been around for C , calibrachoas have only been on the market since the late 1980s .
But they have been a smash hit ever since , with their popularity sailplane since Million Bells ® was first sell under the prescribed trademark in the former 1990s .
In the wild , calibrachoa originate on bouldery talus and the edges of cliffs . This means these plants prefer well - drained soil .
And while they have been selectively bred to cope with a much all-embracing range of conditions , they will still clamber in particularly alkaline garden soils .
Petunias and calibrachoas were once class under the same genus , Petunia . Now considered part of a separate genus known asCalibrachoa , there are around 28 species in the wild .
The cultivated varieties have a much more comprehensive range of colour than petunias and are capable of producing more gloss combinations as well . Some varieties have double blooms , and compact cultivar are also useable .
Calibrachoa Plant Propagation
Calibrachoa is easy to grow , comparatively drought tolerant , and can be purchased at most garden center from spring onwards .
The most cost - efficacious way to purchase them is as little plugs which can be raise in small crapper in thegreenhouseuntil the risk of frost has passed .
They are also well-heeled to propagate yourself from seed or cuttings .
From Seed
intercrossed diverseness of calibrachoa wo n’t uprise genuine from source ; you must buy them as small plants or take cuttings .
Also , because Million Bells ® is a trademarked flora , you ’re not allowed to propagate it . However , true species plants can be grown from seed .
Sow in early spring or in fall in containers place in a tender greenhouse or on a gay windowsill . You will involve to protect seedlings from hoarfrost .
Fill a small lot or tray with come - starting commixture and sprinkle your seeds on the Earth’s surface . Cover lightly with vermiculite ; this will avail the source retain moisture and get some brightness .
water supply well and let the excess piss drain away so the stain does n’t get waterlogged .
The seeds take between 10 and 14 24-hour interval to shoot . They will need to be in a gay spot and kept moist to check healthy seedling growth .
Once they have one set of come leaves and a set of true leaves , they are quick to pot up as described below .
Grow them inside until the risk of exposure of frost has passed before hardening off to transplant open .
From Cuttings
take cuttings from calibrachoa is easy ; the only difficulty is selecting the proper piece to swerve .
As the name “ million bell ” suggest , calibrachoa produces many flowers . To take a cutting , you need to regain a objet d’art with no flower so that it can put vigour into rooting instead of flower .
This is best done in early spring . Take a cutting about six inch farseeing and take away the lower leafage .
brook the cutting in water somewhere gay and give it some unfermented water every few days . In a few weeks , source will form , and you’re able to pot up the cut .
From Seedlings/Transplanting
To transfer calibrachoa seedlings , gently tease each seedling out of the soil while holding onto a foliage , not the root word . Place each seedling into its own low pot satiate with pot stain .
take into account seedling to continue to produce until they are a few inches grandiloquent , with several sets of leaves , and then transplant them into their final emplacement in the garden .
It ’s best to indurate off industrial plant that have been grown indoors for a period of about a hebdomad , to give them prison term to adjust to out-of-door conditions . This is n’t necessary for outdoor nursery - produce fireplug .
Simply pick out a protected location out of direct sun and place the plants there for about half an hr before bringing them back inside .
contribute 30 second to an hour each 24-hour interval , move into gradually brighter conditions as well , until they can hold up the environment where you wish to plant them permanently .
Be certain to traverse transplanted roots with free - draining soil without cut through the crown . pee in well .
How to Grow Million Bell Flowers

The universal rule is that calibrachoa enjoy well - drained ground and full sunshine . Since I care playing fast and loose with ruler in my garden , however , it ’s my experience that they will grow almost anywhere .
Of course , they will grow more vigorously in conditions well become to their preferences . But they wo n’t complain too much about being in rich , moist grime in partial shade .
