Geranium rotundifolium (Round-leaved Crane’s Bill)
This project collects observations of Geranium rotundifolium (Round-leaved Crane's-Bill) in California to facilitate identification and prevent misidentification of this species.
Photo tips:
- It’s important to get a picture of the entire plant.
- It's also helpful to get close-up pictures of the face of the flowers, sepals, leaves, and fruits, if present.
- If there are multiple plants in the picture, it’s helpful to crop your photo to focus on the plant of interest.
How to identify Geranium rotundifolium:
- Height: 10–40 cm (4–16 in)
- Stems: There are reddish stipules/bracts where the leaves branch from the stem, like G. carolinianum.
- Leaves: The leaves are variable, more or less round with shallow, rounded lobes, sometimes more angular with pointed lobes.
- Flowers: Petals are pale rose-purple, fading to white in the center with a slight indentation at the tip. Sepals are soft-hairy and have short, bristly awns.
- This is the most common light pink species of geranium.
