Meet the Hardy Geranium (Geranium spp.), nature’s delicate wonder that graces gardens around the world. This perennial beauty hails from the temperate regions of Eurasia, North and South America.

Admired for its charming appearance, the Hardy Geranium boasts elegant, five-petaled blossoms in shades of pink, blue, and purple, complemented by lush green foliage. Don’t be deceived by its dainty demeanor; this plant (similar to Lavender) is surprisingly easy to care for, making it a favorite among both seasoned gardeners and beginners alike.

Most common varieties:

  • Geranium ‘Ann Folkard’
  • Geranium ‘Biokovo’
  • Geranium Havana Blues (‘Noorthava’)
  • Geranium ‘Ballerina’
  • Geranium Maculatum
  • Geranium ‘Mrs. Kendal Clark’


One of the most important things for optimal growth and stunning blooms is to ensure they receive regular water if placed in hot, sunny spots. Other than that, these are the key aspects of caring for your Hardy Geraniums:

  • Soil: a slightly acidic to neutral soil is preferred, and they thrive best in well-drained, medium-moisture environments. Some species even embrace relatively dry soil.
  • Water: As for watering, these low-maintenance darlings only need a drink when the soil dries out. In full-sun locations, be more vigilant with watering to keep them happy.
  • Light: they do pretty well in full sun or in partial shade.
  • Temperature: Temperatures between 65 and 75 degrees Fahrenheit during the day and 50 to 60 degrees Fahrenheit at night create the perfect ambiance for Hardy Geraniums to flourish. While they tolerate a wide range of humidity levels, be mindful of mildew and rust issues in excessively humid regions


Keep hardy geraniums thriving with regular divisions every three to five years. For better control or new plants, divide more frequently. Do this in early spring to early summer, giving roots time to establish before frost. Here’s how:

  1. Carefully unearth the plant, shaking off excess soil.
  2. Use a trowel/knife to separate the root ball into pieces, each with roots and leaves.
  3. Replant each section at the same depth.
  4. Thoroughly water the new divisions.

For geraniums from seeds, some self-seed easily but won’t overrun your garden. Transplant seedlings or sow seeds elsewhere.


As mentioned before, hardy geraniums need minimal attention. After blooming, they may look untidy with numerous wispy stems, making deadheading a challenge. To rejuvenate their appearance and promote reblooming, shear the plants to their basal growth, and within weeks, they’ll bounce back.
