Rocky Mountain Red Dark Geranium

Rocky Mountain Red Dark is a red-flowering selection in Syngenta’s Rocky Mountain™ zonal-geranium series, with mounding, upright growth. The [breeder listing](https://www.syngentaflowers.com/ams/product/flower/70006932) gives the Dark Red product at 14–18 inches tall and 16–20 inches wide, with hardiness zone 10a; the [Canadian PBR record](https://active.inspection.gc.ca/english/plaveg/pbrpov/cropreport/pel/app00004100e.shtml) associates Pelargonium zonale, the denomination ‘Fisrodark’, and the Rocky Mountain Dark Red trade name. ## Site and use Choose full sun or part sun. The breeder describes the series for larger containers and landscape plantings, and identifies heat tolerance and pollinator friendliness. Its mounding, upright habit suits mixed seasonal containers and sunny beds where a clear, mid-height display is useful. ## Seasonal interest Syngenta lists flowering from mid-spring through late spring and summer. The Canadian varietal record describes the florets as red and semi-double to double, making this selection a strong seasonal color accent. ## Maintenance Check container moisture during warm weather and water when the growing mix begins to dry; provide drainage and avoid waterlogged roots. Remove faded flower heads and damaged foliage to keep plants tidy. The listed hardiness zone is 10a, so in colder regions grow this selection as a warm-season annual or protect it from frost.
