Flowers
Canna lilies bring bluff tropical blooms to the garden . But how much room do they postulate and what does their growth pattern look like ? Find out if these striking blooms will naturally spread in the garden or want to be replanted every year !

With towering leaf and dramatic efflorescence , some plant can make your garden feel like an oasis . Canna lily are one of these , but you might inquire if they spread uncontrollably .
These lush semitropic or tropic perennial draw hummingbirds , bees , and butterflies , all while beautifying your garden – but we do n’t want them to altogether take over !
These lily mature from a rootstock , which might be puzzling because “ electric light ” is a far-flung term used for lily . bet on your realm , they can be long - lived . Let ’s discourse the divergence between the two growth system and howrhizomes play a Brobdingnagian part in how much they spread .
The Short Answer
These plants spread via rhizomes , which are secret staunch that put out adventitious root . Each rootstock has growing head call eye . Every eye will produce extra underground growth . Essentially , the more eyes , the more shoots that can potentially raise .
When you buy these works , the description will often say 2 / 3 eyes or 3 / 5 eyes . This gives you an idea of how many shoots will sprout . Each fourth dimension a new shoot emerges , the rhizome also arise . Over metre , the rhizome get big and produces more eyes . In this case , the light solution is yes : canna lily can spread as they grow .
The Long Answer
These expansive plants are idealistic if you are looking for a plant that will spread and fill an empty billet . If you are planting in a garden seam or container , give them plenty of space .
There are a wealthiness ofcanna lily varietiesthat attend dandy in many garden configurations . Their bright flush wreak an raiment of color to a ocean of greens . Overcrowding will affect flowering and leafage yield , so even once they ’ve hit the maximum quad you ’ve lot , you ’ll still want to thin out plants intermittently .
rootstalk are the understanding for their spread . This section will go in - deepness on how they work .
Rhizome vs. Bulb
Bulbs and rhizome are very unlike , withdifferent internal structuresand different orientations . rootstalk are underground plant systems that bind nutrients and produce shoots and sidelong root .
These are essentially hugger-mugger stems that are thicker than the development that occurs on the surface and may best be envisioned by think of a “ hand ” of pep ( which is also a rhizomatic plant ) .
Rhizomes are buckram , with white flesh on the interior and eyes on the outside . In line , bulbs have a teardrop shape and grow sprout through their top . They do not spread underground , although some bulb species develop offshoots , miniature versions of themselves .
Others will split into two or more freestanding medulla as they mature , which is a bulb ’s form of self - propagation ( other than any seeds it may produce ) . translate the difference will help you empathize the canna lily ’s spread as it grows .
Growth Habits of Rhizomes
rhizome stretch forth horizontally , mail out new root and shoot from nodes . node are where the new theme growth pass . root will raise from the bottom part of the rhizomes , and shoot will grow from the top .
Rhizomes are the storage building block for the industrial plant . It ’s significant to protect them from damage . As the rootstock grow throughout the season , they plough into a larger volume .
Eventually , the original rhizome you planted will be suffocate by novel ones . If your mood is too cold for the rhizomes to overwinter in the garden , you may want toremove the rhizomesin the spill cautiously .
Be sure to divide them into littler segments before storage . provide any track surfaces to dry out out and fink over before storage . When dividing , affirm that each department has two to five eye . Discard any slight , clean , or crappy rhizome .
Spacing During Planting
Consider your plant spacing . As these will spread gradually over time , leaving enough space is essential for growth . You will want to leave alone a foot or more between each rootstalk .
deliberate leaving spare distance if planting a chunk with five or more eyes . Smaller rhizomes should still have at least 12 inches of space between each other . If you are plant in a container , see your container ’s sizing . A rhizome in a little mountain may ask to be replanted quickly , whereas one in a larger container will bit by bit fulfill the container .
forfend planting more than 1 - 2 , even in a relatively big container . study them before planting and reckon the number of eye . This gives you a grating estimation of how many shoot will grow and how full your container could get .
Overcrowding
If your plant are too crowded aboveground , consider trimming off emerge shoots at the stain level to help with density . Another option is to remove a few of the rhizomes . you may cut and transfer them to a novel location or discard them .
If you subsist in USDA zones 8 - 11 , thinning at least every two years is recommended . This will assist with overcrowding , and you’re able to withdraw older , weaker plant .
Seeding
If leave , these flowers will produce seed . The seeds shape in a thick fuel pod . When mature , the seedcase burst and drops the seeds onto the land below .
Typically , the seeds overwinter in the soil , then pop up the following natural spring ; for hoi polloi who already have a dense standstill , this self - sowing habit can become a job . Reseeding is a problem in zone 8 - 11 , where the soil does not typically freeze .
This is less coarse in zone 3 - 7 , but many variety tolerate at least a small level of natural inhuman stratification and may endure the chilly months .
Ifgrown in their ideal condition , the rate of spreadhead might storm you ! To prevent reseeding , remove the flowers once they wither but before the plant educate its seminal fluid pod . This helps controller spreading .
Final Thoughts
If you are design on develop canna lilies , it ’s essential to understand how they spread out . right spacing at planting time may economize you a lot of hassle later in the summer .
Prevent overcrowding by deadheading spend flowers , and if a works becomes too packed in its container , divide it and deal it with your family and friends !
