Cascading Geranium
Pelargonium peltatum
flowerCascading geraniums, also called ivy geraniums, are tender perennials prized for their trailing habit and abundant small flowers in shades of pink, red, white, and purple. They create stunning displays in hanging baskets, containers, and window boxes with their long, flexible stems that gracefully spill over edges. Unlike zonal geraniums, they have ivy-like foliage and require slightly different care.

Seedling/Young Transplant
2-3 weeksSmall plants with initial true leaves and ivy-like foliage beginning to show characteristic shape
Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation. Pinch growing tips to encourage bushiness if desired.
Vegetative Growth
3-4 weeksPlant develops trailing stems and dense foliage; no flowers yet or minimal flowering
Water moderately, allow soil surface to dry between waterings. Feed with balanced fertilizer every 2-3 weeks. Remove any weak or damaged growth.
Flowering
8-12 weeks or until frostSmall flower clusters (umbels) form along stems in shades of pink, red, white, or purple; plant becomes fuller
Switch to lower nitrogen, higher phosphorus fertilizer to promote blooming. Deadhead spent flower clusters to encourage continuous blooming. Maintain consistent watering.
Peak Production
6-10 weeks depending on climateAbundant flowers covering the cascading stems; trailing growth is prolific and dramatic
Continue regular deadheading. Water when top inch is dry. Feed every 2-3 weeks. Ensure excellent air circulation to prevent powdery mildew.
Winter Dormancy/Rest
2-4 months or until springIn frost zones, flowering slows or stops; in zones 10+, may continue blooming year-round
In cool climates, bring indoors or treat as annual. Reduce watering and fertilizing. Cut back stems by one-third in late winter before spring growth resumes.

Harvest Tips
Cascading geraniums are ornamental flowers, not typically harvested for food. Deadhead spent flowers (pinch or cut clusters off) regularly to encourage continuous blooming throughout the growing season. Cut stems can be used fresh in arrangements. For propagation, take 2-3 inch stem cuttings in spring or summer, root in moist soil, and grow on.
Fun Facts
- 🌱 Cascading geraniums are native to South Africa and thrive in sunny, dry conditions, making them naturally drought-tolerant compared to many other bedding plants.
- 🌱 Ivy geraniums (Pelargonium peltatum) have ivy-shaped leaves due to convergent evolution with actual ivy plants—they're not related despite the common name.
- 🌱 A single cascading geranium plant in a hanging basket can produce hundreds of flowers over a growing season with proper deadheading and care.
