Buddleia Candy Lila Sweetheart are charming dwarf buddleia garden shrubs with dense foliage. From July to September these real plants are covered in panicles of small lilac-purple flowers with bright yellow centres. These are highly scented plants with each little bloom is bursting with nectar. This makes small flowering shrubs irresistible to pollinators such as bees and butterflies – hence the plant’s common name of Butterfly Bush.
