Pelargonium x Ardens is a winter growing plant, it should get lots of sun in winter and cool temperatures. Cool night temps along with lengthening days will help the flower buds form, just as with regal pelargoniums (P x domesticum). It blooms in spring. In summer it goes dormant, should dry off at some point when the leaves yellow, then restart by watering in September or October. Propagate by dividing the tuberous roots just before growth resumes in fall, or if you are really good with plants, try stem cuttings (there isnt much stem on this one) in fall. Ernie Tuckahoe NY Z6/7
