Bluebells - planted on graves to bring peace and blessings, and may also be used to decorate the altar at the funeral, or on Samhain
White Lavender and Sapphire Rose Bouquet. Blue roses mean true romance and I think white lavender means everlasting love.
Hellebores (Lentin Rose) A must have for any garden. There is a variety which produces light green flowers - very pretty and unusual.
