Plug plants can be grown to order in any numbers and combinations of varieties.  Each plug is 33p, plus carriage charge.   Please telephone or e-mail your requirements. Plugs are particularly convenient and cheap if planting large areas, such as a meadows or a whole border - the disadvantage being that the plants are smaller and less established than their pot-grown counterparts, and so will probably not flower in their first year of planting.   For plug-grown plants, payment will be needed in advance.
