Buy the bulbs or in the green and put them in shady ground (they like woodland areas and) I dont do more than that but I do hope you get English Bluebells?

Obtain Non scripta the native bluebell from a reputable supplier and decide where you want them to grow. They will decide later anyway!!!!!! Follow any instructions on planting. If you have any kind of a slope ,as I have, they seem to go slowly downwards. So if you want an area clear of bluebells plant partway down and the top will stay relatively bluebell free. Be particularly fussy about buying non scripta if you are anywhere near a bluebell wood. As pollination can cross them with the paler stiffer Spanish Bluebell.
