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.

For over 25 years I have gardened a rockery or rock garden on a triangular patch of poor soil. I progressively scrounged and collected a range of granite, limestone and sandstone rocks and added them piecemeal. I aspired to growing alpine plants and recognised good drainage and shelter from winter wet weather would be key but that is as far as my planning would go. For the first couple of decades I was busy at work and wasn’t able to put in the effort of looking after small but hardy alpines.
One of the consequences of this lack of time was that I took the easy way out and planted ‘Dwarf and slow growing conifers’ that were a popular fad at the time. I also supported many alpine nurseries with my often ill chosen plant selections in attempts to buy a ready made garden feature. Latterly I joined the Alpine Garden Society and took advantage of shows and seed exchanges.
Then a latter stage crept up on me. The 10-20 year old conifers started to take over in scale and dare I say interest. Firstly dwarf can be a misnomer just because a conifer is small when planted it may very well just be a slow grower that has higher ambitions. I true dwarf conifer is a genetic feature of some species and are worth seeking out at the expense of other mass grown shrublets. Over time I dug out the larger and more boring specimens but still the alpines became less significant. I now have 20+ conifers of varying forms, colours and species taking over the alpines. The highest is 6 feet tall and may be the next for the chop one is low growing but spreads 5 feet wide and a favorite on mine is only 9 inches high. The space is still approximately 200 square feet but is extending into and adjacent bed past the crazy paved path.

In Yorkshire we are lucky to have several gardens designed using the theme of a Himalayan Garden. The Hut near Ripon at Grewlthorpe is  ‘The Himalayan Garden’ with all the plants you would expect in such a setting including
A call this a rock box as it is one way of displaying rockery plants above ground level.
Now part of this garden is down to crazy paving the Qualcast grass box is needed less and can be put to a different use. It looks like a ‘unibarrow’ has got in on the act to make a feature planter for these pansies.
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.
A rock garden is a grand place to display your alpine plants. You can shade them with rocks, provide deep root runs and provide rain cover with perspex roofs
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.
