Spurflower (Plectranthus)

Plectranthus is a varied genus of annuals, evergreen perennials, semi-succulents, and shrubs in the mint family. Because this record names the genus rather than one species, flowering, mature form, and cold tolerance vary by the selected plant. [North Carolina Extension Gardener Plant Toolbox](https://plants.ces.ncsu.edu/plants/plectranthus/) ## Placement and use Many Plectranthus are grown in hanging baskets, containers, or the front of a border, and can add color during the growing season. NC State recommends amended, well-drained soil and exposure from part sun to shade for the genus. Use those as broad starting conditions and check species-level guidance for a particular plant. ## Seasonal interest The genus includes both annual and evergreen perennial plants, with forms ranging from erect to cascading. This flexible habit makes Plectranthus useful for seasonal foliage displays, mixed containers, and shaded borders; individual flower and foliage colors depend on species or cultivar. ## Maintenance Keep the root zone well drained and avoid persistently wet soil. Check leaves for mealybugs and spider mites, and watch for leaf spots or root rot, which NC State lists as possible problems. Match watering and winter protection to the identified species, since this genus does not share one hardiness profile. ## Queensland bushfire guidance [Queensland's guidance](https://www.qra.qld.gov.au/sites/default/files/2020-12/0576_qra_bushfire_guideline_v10_pages_print.pdf) lists varieties of Plectranthus. This broad listing does not establish that each species or cultivar was individually assessed; check the source's scope, local suitability and fire resistance.
