Is it classified as a weed?

I have found out the name of a plant (thanks to you guys) that I want to put in my garden, however, it seems that it might be classified as a weed in some parts of the world. How do I go about finding out information about these sort of classifications. I am in Adelaide Australia. Yes, the plant was Silene Maritima Otheriwse known as Sea Camion, or CATCH FLY.
Faye. P.S. Thank you for the previous replies.

A weed is simply any plant that grows where you don't want it. If you plant Silene maritima (= Silene uniflora)(a.k.a. Sea Campion (note spelling)) in a spot where it has room to run and keep it under control, it would not be a weed.

The species is widespread and variable in the Old World flora and has been divided into a number of subspecies, some of which have a much less weedy tendency than others. The ssp. found in mountainous regions are probably less weedy than the coastal ones.

The variegated cultivar Silene uniflora 'Druett's Variegated' is especially slower growing.

hey, cool. that pretty wild flower on the edge of my lawn is Silene Alba. i had been trying to figure out what it was.
yes, it's probably a weed, but it's quite nice looking, and doesn't seem terribly invasive. it's quite pretty in wildflower bouquets.

"A weed is just a misplaced plant." I don't recall who said it first, but it's true. I don't think Silene Maritima is not considered a noxious weed by anyone, so if you like it, it doesn't matter if someone else thinks it is a weed. Some people think of sunflowers as weeds.
Silene noctiflora, however, is considered a noxious weed by some countries\areas.

The definition of 'weed' is often more philosophical than precise. In a local sense, it's something that grows where *you* don't want it, and usually is hardy and reproduces prolifically. However, in the US, Federal and state agriculture departments classify certain plants as "noxious weeds" or "invasive species" that are problems for either crops or urban/suburban landscapes. You should check with your own country's agricultural department(s) for their classifications.

Silene maritima is not considered a noxious weed anywhere I know of.
Its relatives are the troublemakers: S. noctiflora (Night-Flowering Catchfly) and S. latifolia (White Cockle). These are considered noxious in some parts of the northern tier of the US and in many provinces of Canada. (One implication of a noxious-weed designation is that landowners are required to abate any such plants found on their land.)

A listing of noxious weeds databases on the web can be found at the World of Weeds www.ergonica.com. Many of these resources include images to help identify the weeds. Most of these lists are regional in the United States, although there are also references for Austalia.
