Raspberry (Rubus idaeus)

Red raspberry is a deciduous, perennial bramble grown for its edible aggregate fruit and spring flowers. Plants form arching or upright canes, and many cultivars fruit on either first-year primocanes, second-year floricanes, or both; the cultivar determines the harvest calendar. Raspberries are commonly grown in home gardens and small orchards, where bees and other pollinators visit the flowers and birds may feed on ripe fruit. The species profile lists full sun to partial shade and a range of well-drained soils.

Regular irrigation is important during flowering and fruit development, especially in dry weather. Support or tie canes where needed, remove old fruited canes after harvest, and thin crowded growth to improve airflow and access. Check the specific cultivar’s fruiting type before pruning, because fall-bearing primocanes and summer-bearing floricanes need different timing. Use ripe fruit promptly or freeze it for later use. ## Montana Firewise source [Montana State University Extension](https://extension-store.montana.edu/montguides/fire-resistant-plants-for-montana-landscapes) lists raspberry (*Rubus* spp.). This species represents the guide's broad raspberry entry; the source does not individually assess all species or cultivars. Follow local site, pruning, watering and dead-material removal guidance. The Idaho BLM Firewise guide assigns score 6 to a broad raspberry (*Rubus* spp.) entry. This raspberry species represents that source entry; the guide does not individually assess every Rubus species or cultivar. Follow its placement and maintenance guidance. ## New Zealand — FENZ Moderate/high flammability The [Fire and Emergency New Zealand plant directory](https://www.checkitsalright.nz/reduce-your-risk/low-flammability-plants) lists Rubus idaeus / Raspberry in its Moderate/high flammability band (source entry 429). The entry is in the main plant directory, which includes the full range of flammability bands; presence there alone is not a planting recommendation. FENZ advises considering removal or relocation of moderate-to-high flammability vegetation where practical, following local rules; otherwise manage separation, lower branches and dead material. This matches the printed unselected botanical identity. The source does not establish separate testing of every cultivar or regional form. Its bands describe flammability: higher means more flammable, unlike the numerical Idaho resistance scale. Plant condition, site and maintenance affect performance. Keep plants appropriately watered, remove dry material and maintain breaks in vegetation; low flammability is not fireproof. Keep other regional classifications separate.
