I also think it's a cempedak. It's not a jack fruit.

Here you can buy a cherimoya fruit for 1€(approx 1,18$) each

Thanks everyone for replying!
3 years is not much, compared to other plants that can take 10 years. Can't wait to taste my own fruits!

So do you know if refrigerating for a few weeks does actually sterilize durian seeds?

Hello everyone, two weeks ago I planted a durian seed in a pot and placed it in a dark, warm place(about 73°F). The seed came from a piece of durian that i bought in an asian store(it was inside a refrigerator, not that chilly btw). Today, since I haven't seen anything coming out, I decided to extract the seed and look why is taking so long.
The seed is still firm and light coloured, however, no sprouts coming out. Any tip will be appreciated.
Do you know why is taking so long? Maybe it's because it was refrigerated or because it requires warmer temperatures? Do you think it will sprout one day?
Here you are some photos of the seed(it's a bit brown cause it has been inside the pot, not because it's rotting)

Nice work!
I also made a thread of mangosteen seeds germination.
In my area mangosteens are rare in supermarkets, and their seeds are never sprouting: all I did was to buy some seeds on ebay.
Is it a good idea planting them directy in a pot instead of wrapping them in paper towels?

It is just an hypothesis. Just asking for opinions

I have a question:
Since I will be away from home for many months during the year, I have not much time to sow my melon/watermelon/cucumber seeds in spring. So, I'm planning to plant them in september (a week before leaving) inside some little containers. I will tell my sister to give water and to bring them indoors during winter. When I will be back at the end of may, I will finally plant them in my garden and take care of them.
Do you think I will be successful doing this? Will the plants be alive?

Can you recognize this tropical tree？

（Tell me if images cannot help identifying）

How much did he spend for it？If price was relatively high, it can be a Musang King or Red Prawn. If price was lower, it is probably a D24 or Kampung

Ok thanks, but seeds seem enough developed

I wrapped them in a moist paper towel. What is the best way to germinate them?
All the seeds that I planted directly in the soil have become rotten. Why?

Has anyone heard about Narcissus variety?

No, it is the same variety
