Rockery ... mission

Hi, 

A few years back my husband took a saw and a spade to the rockery in the garden .... at the time I wasnt bothered as I worked and didnt have time for the garden.  NOW I am lucky to be a stay at home mum and its now bothering me .... where we had a mature rockery is now just covered in grass.  So this morning I started the very long job of digging out the grass roots, proning back what didnt get murdered and making sense on what we have left..... there is alot of bear soil. I dont want to spend alot of money on replacing what has been butchered as we havnt decided if its going to stay on a permenant basis, BUT it will be there for this year and next at least.  so is there seeds or plants that will add colour and cheer it all up?  It has full sun til mid afternoon, the grass has taken hold but I am working slowly on getting rid, where the old plants have rooted very deep parts are hard to dig.  Any advice would be great.

Small violas are quite cheap as plug plants too and would look very pretty, as well as not growing too large

You can then keep your eye open at car boot sales for little plants that others are selling as offshoots of their own, decide what bulbs to plant in the autumn to flower next spring etc

Avoid anything invasive for goodness sake 

Tropaeolum majus gives gives beautifull bright coloured flowers which taste like radish
The seeds are cheap and they are easy to grow. You have climbing varietiy and a 'stay on the ground' variety..
