Adriatic Bellflower forms a mat of bright yellow foliage topped by clusters of star-shaped light blue flowers in late spring. The species was discovered growing at the base of Italy’s Mt. Gargano in 1827. Campanula garganica ‘Dickson’s Gold’ performs best when protected by light shade. The habit is vigorous, spreads indefinitely by prostrate to decumbent stems to make a low golden mat eventually.
