Pong Pong TreeI discovered a vendor called Lookmai Decor at Asiatique Night Market on the Chao Phraya River selling Pong Pong tree (Cerbera odollam) seeds on a recent visit when my parents were over from England.

I’d seen these large tennis ball sized seeds before as decorations but never knew what grew from them, so I decided to purchase two to take home with me.

After a week in Bangkok, Kanchanaburi and Erewan we finally made it back to Koh Chang and I dropped both seeds on top of some soil in pots, placed in a sunny spot and watered daily.

Within days a fresh shoot appeared and in a couple of weeks the tree stood at 20-30cm tall. Apparently they grow to 5-10 meters tall.

Pong Pong are a tropical tree native to Malaysia and Singapore but are also a common sight in Thai gardens. They are grown for their fragrant white scented flowers, glossy green leaves and to provide shade.

Pong Pong Tree AKA as the Suicide Tree

One interesting fact to note about the Pong Pong tropical tree is it also known as the Suicide Tree due to the single, mango-sized round fruits being highly toxic. The kernel inside the fibrous husk if ingested can cause fatal cardiac arrest due to the cyanide poison it contains.

Cerberin, a type of cardiac glycoside, has the ability to block the calcium-ion channels within the heart muscle.

Due to this beautiful trees poisonous fruit, the Pong Pong tree in Singapore has been fazed out of road side planting.

I’ll re-pot my trees in the coming months before deciding where I’ll anchor them to mother earth to grow in all their glory.

If you want to grow your own Pong Pong tree, seeds can now be purchased directly from our store. Alternatively next time you’re out and about keep an eye out for this interesting oversized round fruits or seeds. Happy planting.

… and eight months later the pong pong trees are still in containers but are looking healthy and stand around 3ft high. When the rainy season starts we will plant them out into our land.

The Fast Growing Pong Pong Tree

We are now about a year into the life of our first two pong pong trees we grew from seed.

Both of our ornamental trees are planted out in our garden strategically placed to shade the house as they grow and mature.

As of this week they have started to bud and flower as can be seen from the photos below.

However, due to recent circumstances brought to our attention, we are suspending the sale of all Pong Pong seeds until further notice.

    I was looking for these seeds everywhere to grow my own tree, but I can’t find them anywhere? Are you currently selling the seeds/plants or do you know where I can purchase them?

    • Perry Stevens (Post author) April 29, 2016

      Hi Shelly, I may be able to help you with these seeds. I will email you a private message. Perry.

  • Ed May 10, 2016

    Perry I can get virtually any seed as well.
    But hence the issues with toxicity of the plant I’m having a rough time as well.
    If you would be generous enough to help me obtain these seeds as well I would appreciate it.

    • Perry May 10, 2016

      Hi Ed,
      Many household plants and flowers can be toxic if ingested.
      Pong Pong seeds fall into this category and they should NOT be consumed.
      We promote healthy lifestyles, permaculture and travel etc. via our blog.

    Hi Perry,
    Please send me the detail to buy some seeds for my garden.

  • Jason February 5, 2017

    How many seeds come with purchase

    • Perry Stevens (Post author) February 5, 2017

      Pong Pong seeds are sold as a single unit.

      • Jason February 6, 2017

        What part of the seed is toxic? Can i be affected just by touching the seed?

        • Perry Stevens (Post author) February 6, 2017

          The inner kurnel contain cerberin which is toxic. Much the same way as an apple seed contains Cyanide.
          Normal handling of the seeds is safe but do not ingest. These seeds are for growing beautiful pong pong trees from only.

  • Jason February 8, 2017

    I tried to purchase but paypal keeps saying something isnt working when i press the pay now button

    • Perry Stevens (Post author) February 8, 2017

      Test the button our side and it is fine. Let us know if you still have any issues with it.

  • Meg June 7, 2017

    Can this plant grow in Japan? I remember my homestay mom used the shell for decoration. I would like to use them in my house.

    • Perry Stevens (Post author) June 7, 2017

      I don’t see why you can’t grow a pong pong tree in Japan as long as you are not on a snow covered mountain.
      Many people do not plant the seeds and instead use them as decorations. They are a great conversation piece.

  • Shellie June 17, 2017

    I live in Arkansas and our temperatures range from 35 degrees in winter to 110 degrees in summer…Do you think I could grow these trees here? I LOVE LOVE the blooms…Looking for something different. Thanx

    • Perry Stevens (Post author) June 17, 2017

      I’m no expert regarding such temperature swings but pong pong are quite hardy trees that grow fast here in the tropics. I think if you protect them when they are young from the extreme cold they will be OK. Be interested to hear of your progress.

      • Shellie July 12, 2017

        Maybe if we start them now while warm/hot they will be OK. Need a barrier between my property and another. Would also like try try growing blueberries if you have in stock.

        • Perry Stevens (Post author) July 17, 2017

          Hi Shellie,
          They would make a very attractive barrier between two properties.
          If you would like some blueberry seeds, please make your order and we will have them sent to you within 24 hours.

  • trea August 2, 2017

    hey Perry,
    I haven’t heard back from you. is everything ok?

  • Martine February 18, 2018

    We just returned back home from Thailand where i found a Pong Pong seed on the beach. It’s quite decorative and I brought it home with me.
    I wondered what it was and searched it on the internet. And now I know! 🙂
    Do you think I could grow it succesfully in a pot in our house? I live in Belgium, so planting it in our garden would definitely not be a good idea.

    • Perry Stevens (Post author) February 19, 2018

      I don’t see why you can’t grow a pong pong in a pot in your home. You may have to heavily prune it at some point though! 55

  • Grace April 23, 2018

    Hi, perry! I am grace.
    I have a question about pong pong tree.
    I bought this seeds yesterday in Thailand market.
    I wanted to send to my mom for gift.
    But I was shock, when I searched about growing this seeds. Because of toxic.
    can I grow this seed just Home deco?
    I am really worry about Harmful to My mom.

    • Perry Stevens (Post author) April 24, 2018

      Hi Grace,
      The pong pong seed, like many seeds are toxic if ingested.
      Handling a seed is fine as only the kernal in the centre is toxic.
      Many people use the seeds as decorations in Thailand and of course to grow a beautiful tree.
      It’s very hot here at the moment. Enjoy your time in Thailand; ) Chok dee!; )

  • katawaredokiii August 28, 2018

  • Sam November 6, 2019

    Hi Perry ,

    Greetings !

    How long we can store the pong pong seeds before planting it . Also how to store safely , Is it required to be refrigerated ? Thanks in advance

    • Perry Stevens (Post author) November 11, 2019

      I’m not sure how long you could store a pong pong seed for but I’d recommend just treat them as any other seed. Keep in a dry, cool place and keep away from sunlight.

  • Jeannie February 18, 2021

    Would love a few of those Beautiful pong pong tree’s tell me where to buy.

  • Michelle September 6, 2022

    Hi. My grandma had the same tree in her backyard. Growing up we had fun under the shade of the tree and had made lots of memories. I wanted to grow it too in my backyard but I am having trouble finding a seed due to its toxicity. Can you help me please.

    • Perry Stevens (Post author) September 6, 2022

      Unfortunately we decided to stop selling the seeds after finding out someone bought one for the wrong reasons. Shame because as you say, they are beautiful shade giving trees.
