| If you have a plant that you are having difficulties identifying, why not post an image and ask other residents. To post your image, click on the add reply button and then insert your image using the insert image icon at the top of the tool bar. You can also check out the Weed ID Tool to search for weeds.

| I have an infestation of this weed in a large number of places in my lawn. I can't seem to work out what it is. Can anyone identify it? It looks like some kind of vine. There's flowers forming on it, but I don't know what colour they are (and I don't want to wait until it gets that far advanced to start doing something about it!) Photo attached. Thanks for the help!

| Hi joanne, my apologies for the delay getting back to you. The second last photo to the right looks like water primrose (ludwigia peploides sub species montevidensis) it is a native and water birds will feed on the seeds, The third photo from the left looks like a Lobelia species these are native herbs that can suppress weeds and help prevent erosion, The photo fourth from the right looks similar to Watercress or Nasturtium officinale, it is an introduced plant from Europe. I would be interested to see a photo of the seed pods if it has any on it? I'm wondering if you could send us a copy of the original photographs, or post some images showing some close ups of the leaves and flowers which would help with identification? If your interested in knowing more about protecting biodiversity in Brisbane, Council offers some excellent programs for private landholders which include the Wildlife Conservation Partnership Program (available for landholders who can preserve or create 0.5 Ha of habitat) or the Creek Rangers program that care for creeks and catchment areas within Brisbane.

| Hi there, Anyone got any ideas as to the identity of these weeds. They are rapidly taking over our lawn and popping up in pots and between rocks,driveway edges. They die with application of broadleaf weedkillers but have just kept on multiplying throughout particularly after our recent rainfall.  
 
In the lawn both grow like groundcover/ creepers but the weed in image 3 does grow up when found in pots. On the ground in lawn he cover is dense almost cloverlike in distribution. Thanks for any help. Steve

| Hi Steve My apologies for the delay in replying to your post, I am almost certain the first two photos are of a plant named Chamaesyce hirta - commonly known as garden spurge or asthma plant Stems often prostrate, hairy, with milky sap, opposite leaves, 12 - 2cm long, elliptic, often blotched red, toothed along margin. "The plant reproduces by seeds which are produced abundantly, as many as 2,990 per plant. When the seed pods mature they explode, throwing the seeds some distance from the plant. In most tropical or subtropical areas the plant flowers year round". Best advice is to remain vigilant and ready to treat the plants as soon as you can (before they flower). I understand that this is not always practical so in lawn areas try to work towards having a healthy lawn that is cut around 4 - 6cm high. By having a thick and vigorous lawn it should suppress some of the seeds from germinating. As for gardens and pot plants look at mulching them with anything from compost, mulches or even stones, whatever you decide to use will need to be at least 75mm thick to prevent seeds germinating. If removing this plant by hand beware that the milky juice of this weedy herb can cause skin irritation in sensitive individuals. I'm not so sure on the third and fourth pictures it looks like two different plants? To help with identification some close up pictures of the leaves and flowers/fruit, it would also help to know if the plant has a milky or clear sap? Kind regards Iain

Hi,
Last year in September, the council removed a large street tree at the front of our house which had become rotten in a few of the large branches. I had originally told the council about it after a large branch fell to the ground one night. They removed it soon after, along with the stump, which I thought was great.
There must have been a vast underground root system, because new shoots started popping up everywhere. At first I just started mowing over them, but they were very fast-growing, and eventually got the better of me. Now we have lots of these small trees at the front of our house.
I am interested to find out what type of plant it is. I have tried using the weed identification tool, and I was shocked to find that they might actually be camphor laurels. I have compared the leaves and so on with some other photos on the web, and it looks a bit different, but I cannot determine what else they might be. I thought if I post some photos, someone might have more of an idea.
Cheers,
Phil

A neighbour has suggested that they are some type of fig. Something like a bodhi or even a banyan.
I should also mention that the original tree was deciduous. Does that mean it cannot be a camphor laurel?

| Hi Phil, I agree that as it is deciduous it is definitely not a Camphor laurel. From your photos I would hazard a guess that the plant is either a Chinese Tallowwood (Triadica sebifera) or a Populus (Populus tremuloides). Both plants can sucker readily from roots and are deciduous. Without having seen the parent tree it is difficult to determine which of these plants it may be. Some of the differences between the two species are; Populus tremuloides has smooth white bark, serrated leaf edges and the seed is a tufted capsule (seed has a small bunch of hairs on one end). Triadica sebifera has rough dark bark with longitudinal fissures, leaf edges are smooth, three seeds are contained in a capsule with each seed surrounded by a white covering which gives the seed the appearance of popcorn. To confirm the identity of this tree I would need to know what the flowers or fruit/seeds of the tree look like. If you could recall seeing them on the original tree it would certainly assist in a positive identification. If looking to remove the suckers it would be best completed by using a control technique referred to as cutting and swabbing. You can find out how to obtain the best result with this technique by checking out the weed control methods found at www.brisbane.qld.gov.au/weeds Kind Regards, Iain
