A Choking Hazard


Some of the Goyer’s showed interest in a photo of a water hyacinth in flower. For those of you who reside in places were this is not banned for reason of unsurvivability in a growing zone and are considering this for your pond please be aware that at this time of year this plant can grow 2-3 feet every few days and send offshoots of itself at a phenomenal rate. Therefore it needs constant daily attention in your pond which is removal. This is a very heavy plant and some of the removed ones you see in the photo are 6 to 8 pounds and I remove them with a grappling hook so don’t place them in a pond any larger that the length of a pool grappling hook pole. This is why mechanical harvesters of this plant in infested lakes are really of no use these plants are too heavy to remove and transport away. So if you do decide to have this plant in your pond because of its usefullness and or attractiveness do not slack off in keeping it under control or it can become a choking hazard to your pond. In the photo I have a tape measure stretched out to 3 ft. These plants once dry will be used for mulch they don’t breakdown well enough for the compost bin.

Here is a medium size one 2ft. Note the dense root mass which contributes greatly to the plants weight. Also note the flotation bladders at the base of each leaf.

Here is a cross section of an air bladder revealing the individual air chambers that keep this heavy plant afloat.
In my previous blog Greenfinger mentioned that her sister on a visit to China witnessed their water hyacinth problem first hand. This plant is native to the Amazon water basin and has its presence felt worldwide and is presently choking Lake Victoria in Africa to death.

Yes indeed. This plant has invaded waterways in the south of England and is wreaking havoc. Pity as it is beautiful. But they are hauling it out of the chalk streams at a frantic rate. The flotation bladder is incredible...fascinating! Thanks for sharing.

Yes once again thankyou L'strife, I know it hasn't been for sale in any of our local acquatic centres for a long time but that I'm afraid won't stop an unsuspecting person from possibly getting one from a friend or even a carboot sale, that's why I brought it to Pamelanne's attention on your other blog, she didn't realise it was on the banned list.....

the physiology of water plants is amazing. stems of water lilies have a similar arrangement too.

we tried to grow it in our pond years ago but they didn't survive the winter.

Luckily Seaburngirl. You wouldn't want a plant that has the ability to clone almost every piece of itself growing in a favorable climate as in as Cottagekarer mentioned, the south of the U.K. Fast dominating growth rate, large yield seed production which have the ability to germinate for 28 years, able to duplicate itself via runners, the ability to clone itself as well and a very attractive flower to entice we humans to take it and bring it home with us....this plant has "thought" of everything.

You are absolutely spot-on right, Loosestrife. I hope everyone heeds your warning.
