A citronella geranium kind of looks like a giant, curly leaf, parsley plant! The dark green leaves have several frilly lobes on strong stems and the entire plant can grow up to 3 feet tall (90 cm). The foliage evergreen and releases a citrus scent that becomes stronger when the leaves are crushed. The citronella flower is small and lavender, and its 5-petal shape is similar to other pelargonium blooms, with burgundy veins decorating the upper two petals. These blooms generally appear in spring and early summer.

While they both carry the citronella name, don’t confuse the Citronella Geranium with the true citronella which is a grass (Cymbopogon nardus or Cymbopogon winterianus). As such, the easiest way to tell the difference is to look at them. If you’re seeing foliage instead of grass, you’re likely getting the citronella plant which often refers to the Citronella Geranium. Citronella Geranium Does Not Repel Mosquitoes

Of course, with the temperature outside still in the 40's, mine is being grown indoors as a potted plant. Much warmer weather is expected by the end of the week. But my house plants won't go back outdoors until all danger of a killing freeze is over sometime in May.
