The colour of this young Knapweed is dark almost purple. As it opens fully it will become blue and then fade as the flower ages. The colour helps Centaurea montana earn its nickname of Mountain Cornflower or perennial cornflower.

Ants can be an unsightly nuisance and inspire concern. However they do not directly damage plants but are more a sign that you have another pest problem.
Ants eat the honeydew secreted by aphids, scale insects and other pests. So ant go where there is food and are clever enough to farm aphids by carrying them from one plant to another to increase their food supply.
Ants can burrow into the soil of seedlings disturbing roots.

Lily themed week shows some more waterlilies and tips for a happy pond.
White is the second most useful colour in the garden after green. I am progressively increasing the number and variety of white and grey plants that I grow.
Britain has some of the best gardens in the world. The choice of which to visit is far larger than this selective list but at least it gives you somewhere to start planning this years outings.
In the cold wet winter it is a good time to plan where to visit as the year improves. The South West is the obvious place to start your visiting tour of gardens containing exotic plants.

Your own rock garden does not have to be as large as that at Kew. You do not need to demonstrate every regional zone on the planet. Nor do you need specimen plants that grow in all the range of soil conditions and climates. Better to concentrate on doing one or two things well.
