What it actually is
Start with the thing almost every listing gets wrong: D13 is not a registration number. It looks like one, it sits alongside D24 and D101 on stall boards, and it is not one.
The name comes from Batu 13 in Pagoh, Johor, the place Durianed says the variety is most associated with. Some sellers write it as B13 for that reason. Durianed adds that, by legend, the 13 refers to the 13th mile, where the original mother tree stood. Some people class it as a kampung breed because, in Durianed’s words, it “has no official status in MARDI”. Durianed reports that “in 2022, it was registered with the number D226 and official name Hock 13”. We have not found the register entry itself, so treat the year and number as Durianed’s report.
So when you see “D13” on a board, you are reading a place name that got mistaken for a clone number and then stuck. The register entry that actually corresponds to it is D226. You can see where it sits among the properly numbered clones in the full register.
How to spot it
Per Durianed, the husk is often a fresh green, and the top half is usually, but not always, wider than the bottom, giving a somewhat ovoid look. It describes the fruit as generally small, with spikes that “look fat and solid”, and a raised little rim of spikes where the thorns meet the stem. FairPrice lists a “bright green husk”.
The base is the giveaway. Durianed says D13 has a bald spot at the bottom, like Musang King, but without the star pattern that runs along the seams of the latter.
Inside, SAYS describes the pulp as “reddish-dark orange” with a thin membrane, and Durianed says it can also be bright orange. And the seeds are large, which FairPrice, SAYS and Durianed all report. That matters commercially: Durianed estimates that with gigantic seeds you could be looking at just 150g to 250g of consumable flesh from a 1kg durian.
What it tastes like
SAYS describes the flavour as “mild, sweet with a hint of floral vanilla notes”. Durianed calls it “sweet with a hint of floral vanilla” and says it is “not a cultivar known for bitterness”, though it adds that D13 can sometimes carry the bitterness of premium cultivars. SAYS gives the texture as “creamy, soft, and sticky”.
FairPrice, which sells it as Singapore Red Prawn, calls it “fragrant, sweet and sticky” and says it is perfect for a newbie. Durianed says the smell is “much less pungent than the most powerful of durians”.
Against D24 the colour is the easy difference. The Department of Agriculture describes D24 segments as pale yellow and the flesh as sweet, rich and slightly bitter. D13 is deep orange and described as mild and sweet. Against Musang King it is not really a contest of quality so much as of intent: SAYS calls Musang King “rich and bittersweet”, and D13 mild and sweet.
What to watch for
D13 is often sold in Singapore under the name “Red Prawn”. Durianed says it is marketed that way “with no relation to the original red prawn cultivar from Penang”. Authentic Red Prawn is D175, which FairPrice lists as the Penang Red Prawn. Durianed notes that some sellers label D13 “Singapore red prawn” to tell it apart, which is a useful tell rather than a reassurance.
The confusion is understandable. SAYS says D13 is “often mistaken for the Red Prawn due to the similar colour and shape of the fruitlets”. Three things separate them:
- Husk. D13 is fresh green. FairPrice lists D175 with a “dusky brown husk with petite spikes”.
- Base. D13 has a bald spot and no star pattern. DurianPro says D175’s thorns “extend all the way down to the bottom of the fruit”, with no bald spot.
- Seeds. D13’s are large. Specialty Produce describes D175 with “small to medium-sized seeds”. Big seeds point away from D175.
This matters because you are usually paying a premium for the Penang name. Ask which one it is, and look at the base before you commit. If you want the general version of this check, the guide to choosing durian covers the stall-side sequence.
Who it suits
This is a reasonable first durian. Durianed says its subtler aroma and taste make it a good choice for people new to durian, and FairPrice calls its sticky sweetness “perfect if you’re a newbie”.
It also suits anyone buying for a mixed group where not everyone is a convert. Serve it alongside something bolder like Musang King or Black Thorn and let people find their own level. During the 2026 glut, Malaysian prices fell to roughly half of 2025, but the glut ended in mid July, so check the 2026 season update for where prices are now.
