Purple-flowering raspberry Rubus odoratus
ABOUT
The plant commonly known as purple-flowering raspberry bears broad, maple-like leaves that have a coarse, hairy texture and are often deeply lobed with jagged edges. The foliage tends to be bright green and can create a lush backdrop for the flowers. Blooming from late spring to early fall, this plant showcases clusters of showy, fragrant flowers. Each blossom possesses five large, light- to deep-pink petals forming a shallow cup or saucer shape, contrasting with the central yellowish-white stamens. After flowering, it produces soft, flat, red berries which resemble raspberries, but they are not as prickly and generally not considered as flavorful as their more popular relatives. These aggregates of small drupelets are edible, although they're often left for wildlife to enjoy rather than being harvested for human consumption. The overall impression of the plant is one of lushness and ornamental beauty, with a naturalistic feel that can attract pollinators like bees and butterflies to a garden.

WaterFor the purple-flowering raspberry, or Rubus odoratus, maintain consistently moist soil without letting it become waterlogged. In general, water the plant deeply once a week with about 1-1.5 gallons, adjusting for rainfall and temperature changes. During the growing season, increase the frequency to twice a week if the weather is particularly hot or dry. In winter, reduce watering to match the plant's reduced need as it goes into dormancy. Always check the top inch of soil for dryness before watering to ensure you're not overwatering.
LightThe purple-flowering raspberry thrives in partial shade to full sun. It's adaptable but prefers a spot that receives dappled sunlight throughout the day or direct sun in the morning with some afternoon shade. Avoid locations where the plant will be exposed to harsh, midday sun, which can be too intense, especially in hotter regions.
TemperatureThe purple-flowering raspberry can withstand a range of temperatures but grows best in conditions between 60 and 75 degrees Fahrenheit. It should not be exposed to temperatures below 20 degrees Fahrenheit, as this can damage or kill the plant. During periods of extreme heat, providing some afternoon shade can help protect it and keep temperatures around the ideal range.
PruningPrune the purple-flowering raspberry for shaping, to remove any dead or diseased wood, and to encourage fresh growth and flowering. The ideal time for pruning is in late winter or early spring before new growth starts. Annually remove older canes that have already fruited to make room for new canes. Thin out crowded areas to improve air circulation and maintain plant health.
CleaningAs needed
SoilPurple-flowering raspberry prefers moist, well-draining soil with a pH ranging from 6.0 to 7.0. A mix of loam, peat, and sand in equal parts is ideal to ensure good drainage while retaining sufficient moisture.
RepottingPurple-flowering raspberry does not typically require frequent repotting due to its nature as a shrubby plant. Repotting every 2 to 3 years, or when it outgrows its current container, is sufficient for this species.
Humidity & MistingPurple-flowering raspberry thrives in average humidity levels consistent with outdoor conditions. It does not require any special humidity considerations when grown indoors.
Suitable locationsIndoor
Ensure bright light, well-draining soil, and adequate watering for indoor growth.
Outdoor
Plant in well-drained soil, partial shade to full sun, and water regularly.
Hardiness zone

Life cycleCommonly known as purple-flowering raspberry, Rubus odoratus starts its life cycle from seed germination, which typically occurs in spring under appropriate conditions of moisture and temperature. The seedlings develop into juvenile plants with a rosette of trifoliate leaves and gradually form a woody stem. As the plant matures, usually in its second year, it begins to produce distinctive large, lobed leaves and canes that can grow several feet tall. During late spring to summer, Rubus odoratus enters its flowering stage, creating clusters of fragrant, purple flowers which are pollinated by insects, leading to the formation of red raspberry-like fruits by late summer, though these are not as commonly consumed as those from other Rubus species. After fruiting, the plant enters a period of dormancy during the colder months. The life span of Rubus odoratus can extend several years due to its ability to propagate vegetatively through suckers, leading to new shoots and canes which contribute to its survival and spread.
PropogationPropogation time
Spring to Summer
The most popular method for propagating the Purple-flowering Raspberry, or Rubus odoratus, is through softwood cuttings. This typically occurs in late spring to early summer when new growth is mature enough yet still tender. To propagate by cuttings, one would cut a 4 to 6 inch (10 to 15 cm) piece of stem from a healthy parent plant, making sure that there are at least a few leaves attached. The lower leaves are removed, and the cut end is often dipped in rooting hormone powder to encourage root development. The cutting is then planted in a moist potting mix, ensuring that the leaf nodes where you removed the leaves are buried, as this is where roots will often form. The pot should be placed in a warm, bright area but out of direct sunlight, and kept consistently moist. With proper care, the cutting will develop roots and can be transplanted into the garden once it has established a sufficient root system.
