Lagunaria Species, Cow Itch Tree, Norfolk Island Hibiscus, Pyramid Tree, Queensland Pyramid Tree

We have a mature Norfolk Island hibiscus in our lawn which we knew to cause a bit of itching but never knew how badly the flower pods can...Read More affect some people. Our grandson and grandaughter were playing with the seed pods that had fallen on to the lawn and for the past two days the boy has had a bad allergic reaction to the fine needles contained inside the pods. He has quite large areas of his skin with welt like rashes that itch like crazy. On the advice of our local chemist we have been treating him with Polaramine liquid medication and anti itch ointments. His sister has had little reaction to the needles from inside the seed pods. Obviously one child is more senstive than the other to whatever is in or on the pods.

Its a pity that something that looks quite good in the lawn can be such a problem. It will have to come out unfortunately.

I come from Malta (Europe) and at my place of work there is a single tree of the lagunaria patersonii. It is about 10m high and about 12...Read Morem across. While I would agree about not growing this tree close to homes schools etc, I noticed that honeybees really love the flowers of this tree and It has a long flowering time in early summer. The tree is situated very close to a footpath and dozens of people walk by every day, I have never heard anyone complaining of any ill effects from this tree. Maybe I like this tree because I am a beekeeper and I love to watch the bees hovering around its flowers.

The more I research this tree the more I wonder why people ever plant this abomination. My neighbor has one that is now 30foot high with ...Read Morea trunk of more than 12 inches, I started talking to him about replacing, at my cost this tree with something more suitable for some stupid reason, that changes regularly he refuses. My grandson and his pals can not play on the grass as these fibres given off from the pods hurt and itch, never mind the fact that nothing grows under these trees or even in the proximity.
Can anybody give me substantial proof that these fibres are carcinogenic, they have been described as asbestos type fibre. I know that when the wind blows the fibres are wind borne and even our washing gets contaminated.
I have tried the reasonable approach and now have to go the legal route, any information would be appreciated.

One man's meat .. etc.

My Australian experience - Son was living in NSW coastal city (temperate climate) where these tre...Read Morees were used as street plantings and he was quite taken with them.

When he moved south again, I picked a couple of seed pods. Having identified the plant, I did wear gloves when removing the seeds from the pod.

Result was three seedling trees - not terribly big, but they live in pots - and they flower.

AND they have survived my very frosty (southern tablelands) winters and temperatures down to -7C.

Son and I are both impressed with the delicate little pink hibiscus flowers. This tree and the deciduous syriarcus are the only hibiscus which will grow in my area.

I moved into a property 5 years ago, the neighbour has this horrible 100mtr tall Norfolk Island Hibiscus inches from my house. It towers ...Read Moreover the roof and continually drops seed pods in my guttering - blocking it. Absolutely horrible pods that when it rains its a gooey mess. Not too mention the prickles- overhangs the clothes line, and shades completely that side of house!
I had it confirmed at the local garden centre its species. I'm am not exaggerating about it height. The breadth is huge too.
Its a nightmare. My son is an Ariel Aborist. He won't touch it!
Wouldn't recommend it too my worst enemy.

Agree with all the other negative comments about this tree. I can't possibly think of a good point to it at all.

The local...Read More council (I live in Williamstown, VIC) planted them in front of my house 30 years ago. (after ripping out the Flowering Eucalyptus which were fine...) Ever since then, they have been trouble.

- Seeds are like asbestos. They HURT when they dig into your skin. It is unavoidable; whenever I work outside, my hands will have at least one seed stuck in them, and they are hard to remove. You cannot let kids near them, or they'll end up covered in them and in severe pain.

- They are bad for people who have allergies.

-The sap ruins paint jobs on cars, and they constantly drip sap. So no good to park the car under for shade.

- The leaves/flowers shed all the time and create a real mess in the street, again.

- No grass grows underneath them.



MTVineman - you have no idea what you are talking about. You probably have a very small specimen which is not an issue, but trust me, they're a terrible plant and should never be planted close to anyone.

Sad to see so many crappy comments about this beautiful tree. I do understand though from reading the negative comments which seem to all...Read More be from Australians who were tortured as children with the pods from this tree. All I can say is: Children are cruel. They are some of the cruelest little beings on this planet. But, this isn't about children. It's about this beautiful tree which does very well for me as a potted specimen here in Montana. It goes outside for the summer and rewards me with much growth and beautiful blossoms of dark pink. Yes, they look somewhat like a Hibiscus but not really. Not sure that they resemble any flower except what they are! Being a member of the Malva family, I find it fascinating that there is a tree form in that genus. I love this tree and I will continue to grow it and give cuttings to friends and will continue to recommend it people too. Sorry for those who were tortured by it as children but it's a gorgeous tree. Don't bad mouth it! It's not as if the tree attacked you. Fabulous as a houseplant and blooms prolifically. If you can get one, do it! I imagine it's even more spectacular growing in a zone that it can take and enjoys.

After growing this tree for close to a year, I've discovered several previous comments may be incorrect. When first planted on the barri...Read Moreer island in Indian River County, we had problems with the soil's ph. Leaves were very small and the tree was struggling. We used a soil acidifier on it and within a few months it perked right up and this spring surprised us with blooms. It definitely does not require another tree to set seed as I'm sure there isn't another one within 50 miles of this specimen. Additionally, we had one of the most prolonged coldest winters on record--with temperatures as low as in the high 20's--and it handled this without a problem. Additionally, Marie Selby Botanical Garden in Sarasota has a rather large specimen planted directly on the bay. Even though the seed pods are said to cause itching, one can use caution handling these. With there being so many plants that cause this type of reaction, I don't see any reason to not plant this species because of this plant's one defensive measure.

I never participated but was witness to the awfully irritating effects. I agree with the comment not to plant it around school yards or playgrounds (or anywhere else for that matter).
