Rosa Alba Maxima - Jacobite rose A midsummer-flowering alba rose, Rosa x alba Alba Maxima dates back to the 16th century, and is a double form of the White Rose of York, of Wars of the Roses fame; it became the symbol of the Scottish Jacobites. It’s a medium-sized, vigorous, deciduous, old shrub rose with an upright, bushy habit. The divided leaves are grey-green, and there are few thorns. From July, the shrub bears clusters of creamy-white, loosely double flowers with a muddled centre and golden stamens; and a strong, sweet fragrance. This is an exceptionally tough, healthy, long-lived rose, often seen rising out of the grass round deserted cottages. The Jacobite rose holds the RHS Award of Garden Merit.
