oh wise gardening greenthumbs, please instill a chronic plant killer with your knowledge...
despite my apparent knack for killing plants of all shapes and sizes, i am fixing up our garden (currently looks like the saharah with a bull ant infestation) and i need some plants that are hard to kill, kiddie friendly but are not too ugly either.... they will be in garden beds in part shade but mainly sun....

oh and on another note should i put lawn seed in the (massive) gaps in the lawn do u think or wait for the lawn to grow to cover it?

TIA
