One of the best known and most widely planted cultivars, award-winning Hibiscus syriacus 'Oiseau Bleu' or 'Blue Bird' (Rose of Sharon) is an upright deciduous shrub noted for its large, trumpet-shaped, violet-blue flowers, up to 3 in. across (8 cm), adorned with a dark reddish-purple eye surrounding a cream center. Blooming continuously from midsummer to frost, each flower lasts about one day and stands out against the green foliage of lobed, dark green leaves. A very useful, structural shrub for the back of the border or as a flowering hedge.
