Fun Facts
- 🌱 Ivy geraniums are not true geraniums (genus Geranium) but are Pelargoniums, a distinct genus often confused due to common naming conventions; they originated in South Africa, not Europe.
- 🌱 The 'Summer Showers' cultivar was bred specifically for its exceptional heat tolerance and prolific, self-cleaning flowering habit, making it one of the most reliable cascade geraniums for summer container gardening.
- 🌱 Geranium foliage contains aromatic compounds that can be mildly fragrant; some cultivars have scented leaves, though 'Summer Showers' is primarily grown for its flowers rather than fragrance.
