What are the best outdoor plants for a herbicidal muppet? (ones that could preferably survive a nuclear explosion please)

[MadreInglese]

The only plants I've managed to keep alive are some mini fir trees, some multicoloured heather, and a big yellow and green leaved tree-type plant (see I have lots of technical knowledge )

What else is a good hard sturdy plant that will survive winter, me perhaps sometimes maybe forgetting to water it, and the cat deciding occasionally to sleep in/on it?

Any tips appreciated.

ah, my garden is full of these as I killed off everything that isn't neglectable. I have variegated euonymous, choisya, winter flowering jasmine, evergreen honeysuckle, forsythia and hebe.

Agree with moshie's list and would add geraniums to that, most thrive on neglect and will flower all summer.
Shrubs are generally your best bet, if you have a good local garden centre or nursey then go and see what you like and ask for advice on what will grow well where you are (alkaline/acid soil etc, they will know which you have) and which things are the toughest.
Also suggest getting a basic gardening book from the library, I found ther Matt James City Gardener books useful when I was starting out, they are all easy to follow and good for inspiration.

Excellent, thanks for all those tips

If fir trees and heather are happy in your garden, it's probably got acidic soil which is what mine is. The other big group of things which would be very happy in it are rhododenrons and azaleas - I have only managed to kill one out of about a dozen of those in my garden, so they are fairly safe. Like the term "herbicidal" - I think it describes my skills very well!
