Botanical Name: Pelargonium peltatum
Ivy geranium has a graceful, trailing habit that makes it ideal for a hanging basket.
This ivy leaf geranium sports clusters of alluring flowers, but the 5-lobed foliage that cover its long, slender stems is showy in itself.
You can train the stems to climb, if you want. Climbing geraniums look beautiful on a trellis inserted into the pot.
New varieties offer a big selection. Ivy geranium colors may be white, pink, lavender, purple, orange, salmon, red or burgundy. Traditionally single, 5-petaled flowers, many newer cultivars have semidouble or double blooms. Some are bicolored and patterned.
Shed some light. Give your ivy leaf geranium as much light as you can spring through fall. Move it outdoors for the summer, if you like. Just bring it back inside when the temperature drops below 50°F/10°C. This is a tender perennial that doesn't like the cold.
Pinch and prune. Pinch off new stems regularly to encourage branching and to shape them as they grow. Deadhead spent flowers to keep your plant looking neat and to promote more blooms. Pruning geraniums back hard in spring will keep them compact.
Repot in spring. Ivy geranium blooms best if slightly pot-bound. Move your plant to a pot 1 size larger or keep it in the same pot and just give it fresh potting mix.
Give it a winter rest. Overwinter geraniums in a cool basement or garage with a minimum temperature of 50°F/10°C. Water sparingly and stop fertilizing during this winter rest.
Origin: South Africa
Height: Trailing to 3 ft (90 cm)
Light: Bright light to full sun
Water: Keep soil evenly moist, not soggy. Allow surface of soil to dry between waterings. Cut back on watering in winter, but don't allow the soil to dry out completely.
Humidity: Average room humidity
Temperature: Cool nights (55-60°F/13-16°C) and warm days (65-75°F/18-24°C) will trigger flower buds.
Soil: Peat moss-based soilless mix.
Fertilizer: Feed every 3 weeks spring through fall with a high-phosphorus fertilizer diluted by half.
Propagation: Take stem cuttings in spring and root in fresh potting mix. Geraniums are easy to grow from seeds, too. Sow seeds in early spring.
High-nitrogen fertilizers given to young plants will bring a lot of foliage growth, but few flowers.
To get the most blooms, use a high-phosphorus fertilizer only while the ivy geranium is budding and flowering.
