Synonyms of Pelargonium denticulatum (3) (Updated on 12-26-22): Geraniospermum denticulatum (Jacq.) Kuntze, Geranium denticulatum (Jacq.) Poir., Geranium reticulatum Nocca

Pelargonium denticulatum Jacq. is the accepted scientific name for this species of Pelargonium. It was named and described by Nicolaus (Nicolaas) Joseph von Jacquin in Plantarum Rariorum Horti Caesarei Schoenbrunnensis Descriptiones et Icones in 1797.

The genus, Pelargonium L’Hér. ex Aiton, was described as such by William Aiton in Hortus Kewensis in 1789. The genus was first named and described as such by Charles Louis L’Héritier de Brutelle. Mr. Aiton gave credit to him for naming the genus and possibly used his description.

As of 12-26-22 when this page was last updated, Plants of the World Online lists 283 species in the Pelargonium genus. It is a member of the plant family Geraniaceae with 8 genera. Those numbers could change as updates are made on POWO.

This Pelargonium species was originally from the southeastern part of Cape, South Africa where it grows as an evergreen perennial up to 4’ tall. It is commonly grown as a bedding plant, houseplant, or container plant in the US and is hardy in USDA Zones 10-11. Some information online says USDA Zones 8a-11…

Origin: South Africa
Zones: USDA Zones 8a-11 (10 to 40° F)
Size: The species grows 36-48” tall but ‘Filicifolium’ much smaller

Water: Average water needs

The edible leaves are used as a flavoring in herbal teas and jelly. Essential oils from the leaves are used as flavoring and geranium oil.

I brought this plant home from Wagler’s Greenhouse in 2014. It did very well and I always enjoyed working around it because of the nice fresh scent. I also like the frilly, finely cut leaves. I will have to learn more about overwintering Geraniums and Pelargoniums because sometimes they are not readily available.
