Kratom Strains Explained: Vein Colours and Names
Kratom strains are not separate plants. Every kratom strain name you see in Canada, from Red Bali to White Hulu, describes leaf from the same species, Mitragyna speciosa. The name is a label built from vein colour, a region and sometimes a grade or drying method. Once you know how those labels are put together, comparing products gets a lot simpler.

What a Kratom “Strain” Really Is
In most plants, a strain or cultivar is a genetically distinct line. Kratom is different. The trade uses “strain” loosely to describe how leaf was picked, where it is said to come from and how it was processed. A typical name has up to three parts:
- A vein colour such as red, green or white;
- A region or origin name such as Bali, Borneo, Malay, Thai or Hulu;
- Sometimes a grade or process name such as Maeng Da, yellow or gold.
So “Red Bali” reads as red-vein leaf sold under the Bali name, and “Green Maeng Da” as green-vein leaf sold under the Maeng Da grade name. Researchers have identified genuine chemical differences between groups of trees, but those do not map neatly onto shop names. See Mitragyna speciosa: the kratom tree for the botany.
White kratom in Canada is sold under names such as White Maeng Da and White Hulu. The white part of the name refers to the vein colour of the leaf when it was picked, not to the colour of the powder.
Red, Green and White Vein Kratom
The vein colour names come from the colour of the leaf’s central vein and side veins when it is picked. The trade generally links colour to where the leaf is in its growth cycle:
- White vein: leaf picked earliest, with pale veins;
- Green vein: leaf picked mid-cycle;
- Red vein: the most mature leaf, with reddish veins.
Drying also affects colour, so the finished powder does not always match the vein name. Our strain profiles go deeper on individual names, for example white vein kratom compared, Green Maeng Da and White Hulu.
Green vein kratom in Canada
Green vein kratom is named for the green colour of the veins in the leaf at harvest. The name tells you the vein colour. It does not tell you where the tree grew.
We sell two green vein strains in Canada:
- Green Maeng Da, a grade name that comes from Thai slang.
- Green Malay, named after Malaysia.
Both come in sizes from 50 g for $25 to 1 kg for $200. An outside lab tests every batch for heavy metals, bacteria, mould and alkaloid content. Most GTA addresses get same-day delivery. The rest of Canada gets tracked shipping, usually in 2 to 5 business days, in a plain box.
Red and white vein kratom in Canada
If you are comparing colours, here are our red and white vein strains:
- Red vein: Red Maeng Da, Red Bali and Red Borneo.
- White vein: White Maeng Da and White Hulu.
- Yellow and gold: Yellow Thai and Gold Maeng Da.
All of them cost the same for the same size, so you can compare strains without worrying about price.
Yellow, Gold and Blended Names
Yellow and gold are not vein colours you will find on a tree. Sellers generally describe them as the result of a particular drying method, such as a longer dry or exposure to different conditions, or as a blend of leaf from different vein stages. Because there is no agreed industry standard for these terms, two shops can use the same name for leaf that was handled quite differently.
Blends work the same way. A product sold as a mix of red, green and white leaf, or a named “mixture”, is defined by the seller’s recipe. If you are comparing a blend, ask what went into it and check the batch’s lab report.
Regional Names: Bali, Borneo, Malay, Thai and Hulu
Regional names point to a place, but they are best read as trade names rather than proof of origin. Most internationally traded kratom comes from Indonesia, and some names reflect historic trading routes as much as where a tree grew. A leaf sold as “Bali”, for example, is widely understood in the trade to be a naming convention rather than a guarantee it was grown on Bali.
That does not make the names useless. Within one seller’s range they help you tell products apart consistently. But if origin matters to you, look for sourcing information and a matching batch report rather than relying on the name alone. Where kratom comes from covers the real source regions.
Grade Names Like Maeng Da
Maeng Da is a grade name rather than a place. It is used across all three vein colours, as in Red, Green and White Maeng Da, and it is meant to signal selected, higher-grade leaf. As with regional names, there is no official standard behind it, so the meaning depends on the seller.
The name is popular because it gives buyers a simple way to identify a premium tier in a crowded range. The practical test of any grade claim is the same: a clean, batch-specific Certificate of Analysis and consistent quality from one order to the next.
A Quick Glossary of Kratom Strain Terms
- Vein: the colour of the leaf’s central vein at picking, used for the red, green and white names;
- Maeng Da: a grade name used to signal selected leaf, applied across vein colours;
- Bali, Borneo, Malay, Thai, Hulu: regional or trade names, not proof of origin;
- Yellow and gold: trade names usually linked to a drying method or a blend;
- Blend or mixture: leaf combined from more than one vein stage or name;
- Crushed leaf: dried leaf broken into flakes instead of milled into powder;
- COA: a Certificate of Analysis, the batch-specific laboratory report.
How to Compare Kratom Strains Fairly
Because names are inconsistent between shops, compare the things that can actually be checked:
- The batch lab report: alkaloid results plus heavy-metal and microbial screening;
- The test date and batch number, matched to the pouch you receive;
- Freshness: colour, aroma and texture when you open it;
- Consistency: whether repeat orders of the same name look and test alike.
Our COA guide explains each line of a report, and the shop lists every variety we carry. For how processing shapes each name, read from kratom leaf to powder.
Frequently Asked Questions
Are different kratom strains different plants?
No. They are all leaf from Mitragyna speciosa. Strain names describe vein colour, a region or grade, and sometimes the drying method.
Which vein colour is harvested first?
White vein leaf is generally picked earliest, green vein mid-cycle and red vein when the leaf is most mature.
Is yellow kratom a vein colour?
No. Yellow and gold are trade names that sellers usually tie to a drying method or a blend, not to a vein colour on the tree.
Why do strain names differ between shops?
There is no official naming standard, so each seller applies names their own way. A batch lab report is the reliable way to compare.
Where can I buy green vein kratom in Canada?
We sell Green Maeng Da and Green Malay online. Same-day delivery covers most of the GTA. Everywhere else in Canada, orders ship tracked in a plain box and usually arrive in 2 to 5 business days.
Do all kratom strains cost the same?
In our shop, yes. Every strain powder costs $25 for 50 g up to $200 for 1 kg.
