Rubus odoratus, or Purple-flowering Raspberry, is an attractive, deciduous shrub native to North America. It grows 5-10 feet tall, with small, 2-5 feet shrubs growing around the base. This plant thrives in full sun, with semi-shade in hotter regions, and requires regular watering. As its name suggests, Rubus odoratus produces abundant, fragrant, pink flowers that are not only beautiful, but also attract butterflies and hummingbirds. The plant is considered to be invasive, however, it can be cultivated for edible fruit.

Though the berries are not popular to eat due to the large number of seeds, they have a pleasant flavor and provide many healthy benefits. For example, the fruit contains Vitamin C, fiber, magnesium and other minerals and can be used to make jellies and jams. When mature, the plant is hardy enough in USDA zones 4-9.

Growing Rubus odoratus in a pot requires some extra care, especially during cold weather. It is best to leave it outdoors as long as the temperature falls no lower than 30°F and position it in a sheltered area to reduce wind damage. If necessary, you can use a cold frame or a frost cloth for extra protection, and apply a thick layer of mulch around the base in winter to insulate the roots. In addition, you should check the soil moisture frequently and water the plant when the top inch of soil is dry.
