I bought just three forget-me-not plants about six years ago. They flowered beautifully and looked good in my front garden. I planted them fairly close together to get the benefit of a clump of blue flowers rather than have then spread out.

These are very hardy little plants and they have survived frozen winters in 'far north' without any sign of damage.

After all these years these pretty little blue flowers have become a real nuisance. They dry out at the end of summer and if you don't catch them quickly enough they seed themselves absolutely anywhere and everywhere.

The seeds are particularly light so they do travel a long way from the plants. I now have a problem with them growing in my stone chippings in my front garden. I've pulled lots of them out but they aren't detered. There are always new ones to follow on.

I've weedkillered the whole area which is something I don't like doing but the pesky things still come up.

If you are going to plant these pretty flowers then make sure you dig them up before they seed themselves. They will keepcoming each year if you leave them but your garden will be full of their off spring too. This is great in some areas but there are others where you don't want them.
