Eriogonum giganteum, with the common name St. Catherine's lace, is a species of wild buckwheat in Southern California.

[3] The leathery, woolly, oval-shaped leaves are gray, and clustered sparsely along the mostly naked branches.

The plant flowers with each inflorescence rising boldly above the foliage on strong stalks.

The broad domed blooms are covered densely in carpets of clustered tiny white flowers, that fade to rust red.

[3] With its coarser texture and semi-open form, it can be a good background plant in gardens.
