Royal Purple Smokebush
Red Mammoth Raspberry

Royal Purple Smokebush is an attractive and dramatic shrub. Mid-summer you'll notice feathery, purple-pink puffs of airy seed clusters that give the illusion of smoke. The contrast of these seed clusters against deep purple-red foliage will make Royal Purple Smokebush your new favorite shrub.

It is tolerant of clay soil, drought, and deer, making Royal Purple Smokebush a hardy addition to any yard. Try it in a hedge, shrub border, or as an accent shrub; regardless of how you use it, this shrub will be a head turner.

Developed by the University of Saskatchewan Fruit Program, SK. Red Mammoth was a high yielding and firm variety released in 1999. It produces distinctively large bright red berries about 1 inch wide. It is also more cold hardy than older raspberry cultivars. Red Mammoth is firm which makes it suitable for commercial production and sweeter than Boyne. Floricane.

Needs to be trellised as canes are not as sturdy as other varieties.
