This project collects observations of Geranium yeoi (Greater Herb-Robert) in California for the purpose of facilitating identification and preventing misidentification of this species in iNaturalist.
Vouchers Needed: This species is not yet recognized in Jepson eFlora or Calflora. If you're a botanist and find this plant in the wild, please submit a voucher specimen so that its presence in California can be documented. See this Facebook posting for more info: https://www.facebook.com/groups/Calinvasiveplants/posts/2828241484118285
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 yeoi:
-
G. yeoi is similar to G. robertianum, but the flower is about 3x as large and the pattern is slightly different. It is often a brighter pink and the stripes on the petals are less distinct, making the darker shaded area more obvious.
-
G. yeoi tends to form a clump of leaves, almost a low shrub. The leaves are very substantial and approach the form of other Mediterranean species such as G. palmatum and even G. maderense.
-
G. yeoi grows side-by-side with G. reuteri, with which it also appears to hybridize.
Similar Species:
-
Geranium robertianum (Herb Robert)
-
Geranium reuteri (Canary Herb-Robert)
-
Geranium maderense (Giant Herb-Robert)
