Are they for a lawn or just border plants?? There are different varieties!

Here's a site through Google...

plenty more to look at though!

If it's border plants- then I grew a packet of seeds a couple of years ago directly into the border and they just self seed and thrived on neglect ( I love the sort of plants which tell you they are thirsty by wilting - and then recover fully when watered!!!)
