Flutterby Grande® Blueberry Cobbler Butterfly Bush

Flutterby Grande® Blueberry Cobbler is the trade name for patented Buddleja hybrid ‘Podaras #4’. Its [plant patent](https://patents.justia.com/patent/PP22109) describes sterile light violet-blue flowers with yellow centers and upright, outwardly spreading growth; the [Flutterby cultivar reference](https://www.buddlejagarden.co.uk/podaras.html) links Blueberry Cobbler to Podaras #4 and notes that the flowers fade toward cream. ## Flowers and form The patent records the cultivar’s hybrid parentage and freely produced flower panicles. Its color changes as blooms mature, from violet-blue toward pale cream. The plant forms a substantial shrub with a somewhat spreading outline. ## Siting Choose a sunny, well-drained position and allow room for a broad mature plant. Hybrid butterfly bushes can vary in size and performance with local climate and growing conditions. ## Maintenance Prune in early spring to shape the shrub and encourage new flowering growth. Water new plantings while they establish and during prolonged dry periods. The patent describes this exact cultivar as sterile; that trait does not establish sterility in other butterfly bushes.
