Venice in Italy is an ideal situation in which to demonstrate the potential of ivy geranium, Pelargonium peltatum. Because garden space is so minimal, potted plants that cascade from balconies above the canals are quite popular. Ivy geranium cascades so splendidly that some eventually reach the tops of downstairs windows from their upstairs balconies.
Ivy geranium can sprawl over shrubbery to seemingly climb a few feet high. Otherwise, it is unlikely to stand much more than a foot and a half high on the ground without support. If cascading over the edge of a planter, upward growth may be only several inches high. In window boxes, it obstructs minimal sunlight. However, it may hang six feet downward!
Ivy geranium propagates somewhat easily by cuttings of the almost succulent stems, but not as easily as zonal geranium. Its lobed, rounded and quite fragile leaves are about an inch long and two inches wide. Sporadic but continual bloom becomes more profuse for late summer and autumn. Flowers might be white, pink, red, lavender, purplish or striped.
