These are the true plants! (We waited for some years to have a new stock purporting to be this flower, to find that it was not right). Tall angled stems are typical with large late flowers in a vibrant mid blue. Supplied as divisions.
With South African origins they are all sun lovers, but they would be used to summer rainfall so we suggest they will do better where they aren't too dry. Hence lots of organic matter in the soil to hold the moisture will pay dividends. From division it does sometimes take a while for an Agapanthus crown to flower well again, so expect better flowers in the second year. Plant about 5" deep and 24" apart and protect in winter. To get a more immediately full effect you might cram them in rather tighter together in pots. Remember though to give the pot regular watering through the summer and some liquid feed occassionally.
