For the not-so-green-thumb to the expert gardener, GardenWeb Australia (www.au.gardenweb.com) offers a number of valuable and local resources for gardeners in Australia and New Zealand.
Open forums are offered on several topics including Australian native plants, roses in Australia, and pests and diseases. The forums foster a sense of community, with more experienced gardeners offering advice and information to those who have cries of help.
The site also features tips and a regular online magazine, plus links to other GardenWeb sites in the US and Europe.
And if you're planning a horticultural tour of the globe, "Gardens of the World" will tease your tastebuds with information on the "most interesting botanical gardens" of the world.
