Geranium—Pelargonium spp.
Family Geraniaceae (Geranium family)
Plant Identification
Pelargoniums are woody or shrubby perennial
plants and attract hummingbirds. Don't confuse these with
true geraniums, often called cranesbills, in the Geranium genus,
which have 5 equal-sized petals in contrast to the Pelargonium. Pelargoniums
produce symmetrical flowers, often in clusters but also
singly. Flowers
generally bloom in spring through fall. Colors include
white, pink, red, coral, and purple and may have distinct
markings or blotches. Leaves are roundish with wavy
or lobed edges. Depending on species, leaves may
have a yellow margin or other markings.
Optimum conditions for growth
Geraniums grow well in warm sunny weather, but need
some shade in very hot temperatures. They need moderate
to regular amounts of water, but must be planted in soil that
drains quickly. In areas with very cold winters, move
plants indoors to avoid frost damage.
