Redbud is the common name for plant life in theCercisgenus , which is part ofthe Fabaceae kinsfolk . If you know your botany , then you ’ve likely realized this plant is a fellow member of the legume kin .
Yep , that ’s correct . The Cercis canadensis tree is closely pertain tothe humble garden pea plant .
It ’s a little hard to see the resemblance , but once you get a in force look at the fruit pods or after you sample the seeds , blossom , or youthful leaves , you will more clearly understand this relationship .
Examine those inflorescences shut up , and you ’ll notice that they look a heck of a sight like pea flower .
disastrous locust tree ( Robinia pseudoacacia ) and mimosa Sir Herbert Beerbohm Tree ( Albizia julibrissin ) are also in the same family line .
Cerciscanadensis , which is also have a go at it as the eastern Cercis canadensis , is the one most unremarkably grown in the US .
This species is native to North America , with the largest wild populations clustered in an arena spanning Iowa to Texas and points due east , though you may find them as far northwards as Canada and as far south as Mexico , and anywhere east of the Rockies .
There are three tell apart variety of eastern redbud : canadensis , texensis(Texas redbud),andmexicana(Mexican redbud ) .
Occident of the Rockies , you ’ll findC. occidentalisgrowing in the wilderness , where it is aboriginal . The western redbud is n’t as hardy as the easterly species and can only be grown as far northward as Zone 6 .
These , and species from Europe and Asia such as Judas tree ( C. siliquastrum)and Chinese redbud ( C. chinensis ) , are cultivated all over the US in Zones 4 to 9 .
These small trees work mass of pink , mauve , magenta , or violent bloom in the early leap before the purple - to - fleeceable kernel - shaped foliage leaf out .
Flowers form on older woods on the proboscis and stanch rather than new ontogenesis , which is known as cauliflory .
After the flower slice , seed pods begin to form and grow over the summer , though some cultivars are infertile so they wo n’t produce any yield pods .
The arm have a slight zig - zagging increase pattern along the internodes , and there is oneC. canadensiscultivar key out Zig Zag ® that has exaggerated zigzag - zagging .
In the wild , they lean to maturate in the understory beneath expectant Tree , and as such , they prefer partial shade or partial sun and moist soil . However , many cultivar have been bred to do well in full sun or drouth conditions .
How to Grow Redbud Trees
Most cultivars flower best in full sunshine in cooler regions , or fond shade in hot regions . If you want to assure that your tree thrives , prefer a cultivar or diversity that is well - conform to your climate .
For instance , C. canadensisvar.mexicanaand cultivars bred from it are better off in warm climates , whileC. canadensisvar.canadensisand its progeny do better in cool ones .
You ’re also better off choosing whatever species is native to your region , whenever possible .
To really be happy , these trees need a certain number of chill hr at or below 45 ° fluorine , and the accurate amount will deviate look on the cultivar .
Once again , pick a cultivar or diversity that will tolerate few chill hour if you live somewhere with meek wintertime .
‘ Pink Pom Pom , ’ for instance , has sometexensislineage which makes it more tolerant of warm winters , and it will still produce bloom despite the warmer climate .
The land in the planting sphere necessitate to be well - draining . These tree diagram can brook a range of grease , so long as it ’s well draining with a pH between 6.5 and 8.0 .
Some crossbreed and cultivar are more drouth tolerant than others , but all established Cercis canadensis can handle some amount of drouth . westerly redbud are extremely drought resistant and can go without any supplemental piddle in many parts of the US .
As a general rule of pollex , you should cater water when the soil feels juiceless three in down , and the soil should never be sluggish .
During the growing time of year , feed your plant every other calendar month with a mild , balanced fertilizer .
Fertilizer kick in the plant the energy it needs to arise and stack away up nutrients for that bright showing next spring .
A 10 - 10 - 10 NPK plant food , or something secretive to that , is idealistic .
Pendleton Turf Triple 10 is a good pick that will keep a wide variety of species well-chosen with its special formulation of aminic superman and seaweed extract .

nibble up a 32 - apothecaries' ounce bottlefrom Amazon .
If you decide to get one of these trees in a container , pick one of the smaller cultivar .
Depending on the size of the container , you may expect the tree diagram to stay within about half the sizing of one of the same diverseness raise in the primer coat , so a 12 - foot type will generally stay within a accomplishable six feet .
Choose a container at least 18 inches wide and 24 inches deep , with at least one or preferably multiple drainage holes . Plan to keep the container in a lasting spot .
Though you could move it around if the pot ’s placed on caster , it ’s live to be hard to move such a large container easily when it ’s filled .
replete the container with pee - retentive potting soil . Remember , redbuds are n’t rottenly demanding about soil , but it never hurts to give them the right stuff and nonsense .
FoxFarm Ocean Forest Potting Mix
I ’m a immense sports fan of FoxFarm Ocean Forest potting intermixture , which isavailable at Amazonin 12 - quart bags .
I find this mixing to be perfect for a wide of the mark scope of plants and it ’s produced in a sustainable direction .
good deal wo n’t help to insulate roots against cold temperatures to the same level as ground soil , so pretend you live in an area one Zone lower than your actual garden location if you ’re using a pot .
In other password , if you survive in Zone 7 , choose a plant that ’s hardy down to Zone 6 . You also necessitate to keep a near eye on the grease since it will dry out faster .

Remember , these plant are cauliflorous . The flowers and seed seedpod form on previous , woody growth . That means you do n’t have to do any special pruning to encourage anthesis and fruiting .
Unless a branch transgress or is morbid or dead , it ’s good to just leave the tree alone .
you may always trim crossing or fret branches to start the canopy and improve the appearance . This should be done in other spring before anthesis .
Redbud tree can be propagated from seeds , cuttings , or by transfer untested glasshouse - grown specimens .
We discuss all of the selection in our redbud multiplication guide .
We ’d suggest opting for glasshouse - grown Cercis canadensis tree that are grafted .
Grafted trees furnish predictable characteristics , assure gardeners know exactly what to expect in terms of size , cast , and blossom and leaf colour .
They are clones of the trees developed by plant breeder who cross parent trees , comb out through thousand of seedlings to find possible unexampled cultivars , and then who spend year demonstrate them out before introducing them to the public .
In general , this is one of those Tree that generally maintains serious health so long as you uprise it in the correct surround . If job do add up up , here ’s what you ’re most likely to see :
Herbivores
More so than diseases or dirt ball blighter , avoiding herbivores is going to be the braggy challenge to overcome when growing redbud .
Those animals out there seem like they ’re all too eager to get a bite of your works . Both deer and rabbits will go through vernal trees if apply the hazard .
Your best bet to protect your redbuds from both of these plebeian plague is to beleaguer the young tree with Gallus gallus wire .
Once your tree is tall enough that the leaves and branches are out of reach and safe from browse , you may off the fence .
Insects
redbud are by and large ignored by insect pests , especially if you choose a species aboriginal to your region .
However , that seems to be changing as the fearful emerald ash tree woodborer extend its range into more and more regions .
Regardless , healthy trees are usually capable to hold up an infestation and stay healthy .
The redbud leaf roller ( Fascista cercerisella ) is the larva of a half - column inch - wide glowering dark-brown and white moth that lives east of the Rocky Mountains .
The moth itself is n’t a menace , but the half - column inch - long fatal and white folio hair curler will roll up redbud folio in on the loose webbing , finally killing them .
To hold in this pest , just overstretch off any rolled leaves , bag them , and dispose of them .
Sprays wo n’t unremarkably work since the larvae hide in the little shelter that they ’ve made . as luck would have it , they do n’t typically cause serious legal injury .
The emerald ash borer ( Agrilus planipennis ) is an invasive pesterer from Asia that is rapidly occupy a larger and larger area of North America .
It was first identified in southeast Michigan in 2002 , and identify on the West Coast for the first time in 2022 . In the intervening years , it spread through every state east of the Rockies and throughout Colorado .
There have been reports since of these pest in Montana and Wyoming .
Though they have n’t been formally confirmed at the time of this composition , this indicate that it ’s potential that the hemipteran may be found in every state throughout the continental US .
They decimate ash tree trees , killing hundreds of millions since they were first discover in North America 20 eld ago , but they ’ve also been run into feeding on the leaves of redbuds and other metal money .
These beetle look like pearlescent half - inch - retentive grasshoppers . deal pick and drown any you see in soapy water .
If you have ash tree tree diagram on your property and you spot these pests , you ’ll want to jump treatment properly by . With redbud , your best wrinkle of flack is to keep your tree healthy .
Disease
It ’s rare that a Cercis canadensis is impact by disease , but that does n’t mean it ca n’t happen .
tree grow in squiffy soil , with poor atmosphere circulation , or those that are flow wrongly are more potential to face issues .
canker sore on Cercis canadensis is due to fungi in theBotryosphaeriagenus , and it ’s the most destructive disease of theCercisspecies .
At first , it record up as little black , diffuse , sunken spots in the barque . finally , the pestilence spreads and girdle the stem , causing everything above the pestilence to give way .
Fungicides are n’t extremely effective , so just crop away any diseased branch you see at the base .
If you have a wicked case with lots of cankers and expire branches , you will need to just remove the Sir Herbert Beerbohm Tree .
due to the fungusVerticillium albo - atrum , vert causes the parting to wilt even when the Sir Herbert Beerbohm Tree has plenty of body of water .
As the disease progresses , the leave of absence release yellow and may form quintuplet - shape yellow-bellied spots between the nervure . Overfertilizing and lactating soil make favorable conditions for this disease .
deplorably , there is no treatment available . It ’s best to take out an infected works and dispose of it .
Best Uses for Redbud Trees
First , let ’s talk about how to run through this tree . you could eat up the young leaves and prime either raw or fake .
The leaves are n’t all that great , if I ’m being whole honest .
The really untested ones have a meek flavor and tender grain , but otherwise , they run to be largely savourless or slimly bitter . They make a good salad filler , though !
The pod are also edible , but they ’re best when they ’re young and tender . Sautee them or toss them crude into salads . Basically , you’re able to use them as you wouldedible pea pods .
The blossoms are the tasty part of the plant . These are unbendable enough to fry up well yet bid enough to also eat in the altogether .
If you prefer a sweeter , more tender goody , just eat the paler upper flower petal . you may also pickle the flower buds to make “ capers . ”
humanity are n’t the only ones who love foraging from these trees !
The flowers are pollinated by bee , though only long - tongued bee can reach late enough to get at the nectar .
Butterflies and hummingbird also feed on the flowers . In fact , C. canadensisis the master host of Henry ’s elfin butterflies ( Callophrys henrici ) .
In the garden , these make excellent specimen trees and the semi - dwarf cultivar are everlasting in containers .
If you have a partially shaded smirch that needs a outburst of coloration , a Cercis canadensis is an awesome pick .
Plant some fond - tincture - loving color likephlox , wood lily , reddish blue , orbluebellsunderneath .
Usher in Spring with Redbud Trees
The first tree diagram I ever planted was a redbud . And I had no musical theme what I was doing .
I had just go out of my parents ’ theatre and I wanted a tree diagram to fill the empty dry patch just beyond the reach of the sprinklers at my rental .
I did everything incorrect . It was the amiss post , with pitiful drain and concrete - hard soil .
Ididn’t have a garden hose , so the irrigation it received was intermittent at best . Between the flush of college and time spent hanging out with friend , I forgot to feed it .
Of of course , now I know better – and you do , too ! But I think my story is a will to how toughened redbud tree are . The one I planted way back when is still develop away happily for the current tenants to enjoy .
