Hi I am new to this forum and looking for some advice. I am planning on planting an alpine garden which should take approximately 35 plants - a long narrow walled area app 7 metres. Should I plant e.g. 3 plants of the same together instead of single plants and therefore look at 10 different varieties or should I stick to more plants of the same variety and therefore have about 6/7 different varieties. I appreciate that this is usually a personal preference but just looking for some initial advice. Thanks.
