Large, double, blue flowers. Position: full sun Soil: humus-rich, moist but well-drained, neutral to slightly alkaline soil Rate of growth: average to fast-growing Flowering period: August to October Hardiness: fully hardy Large, double, blue flowers with a neat swirl of smaller petals in the centre appear from August to October. This is an award-winning tree hollyhock that makes an excellent specimen plant for a sheltered, sunny border. Unlike some of the older, double varieties it stands up particularly well to wind and rain. Garden care: To encourage a bushy habit prune young plants hard in late spring. After pruning apply a generous 5-7cm mulch of well-rotted garden compost or manure around the base of the plant. Once established it requires little if any regular pruning. Please note: the plant is supplied in a nursery pot, but if you do wish to pot it up for the patio we have a great range on our website.
