Plants that are impossible to kill

Outdoor plants

Agastache: "Tough as nails," nowhere in Australia is cold enough to kill an Agastache.

Salvia: Commonly called sage, will survive all the droughts Australia can throw at it.

Indoor plants

Philodendron and Philodendron xanadu: While it might be a little boring to look at, it is impossible to kill and will add some nice greenery to any corner of the house.

Kangaroo Paw Bush Gem: Australian icon, this variety of Kangaroo Paw stays smaller, so it's good indoor in pots.

Succulents: The 'it plant' of the season, our horticulturalist refers to them as "the gateway drug to gardening." The best thing about succulents is that you can make a new plants just by snapping off the stem of an established plants and sticking it in soil. Voila!
