    Barberries can be alternative hosts to wheat stem rust fungus. Is Berberis darwinii such a host?

      While common barberry and other Berberis species are known to be alternate hosts of Puccinia graminis (Stem rust), this doesn’t seem to be the case in South America. From what I found, “more distantly related to stem rust is obviously the group of autoecious rusts which live on Berberis in South America”… including Berberis Darwinii.

      From the journal article: Some Viewpoints on the Phylogeny of Rust Fungi. IV. Stem Rust Genealogy (link: http://www.jstor.org/stable/3756583?casa_token=iycD6D6pXyUAAAAA:2-FH8Za2VPjLlaVJAvd7ikyHYJyNoCtoyNyI0YNFQEOfj_9QDofD9NdfS17-Frx9iajIhoT9LX7yRZ5-yZTJwV4sC_4ymtVd3hABuMxarnL_Ns7oEPHE&seq=1#page_scan_tab_contents)

      Cheers

    B. darwinii (and B. microphylla) is known as calafate in Patagonia – the berries are used to make jam and delicious gelato. The scenic tourist town of El Calafate is named for this plant!

    Love this flower color in The Bay Area this time of the year! Great bird habitat too!

    The calafate breeders are trying to reduce the size of or eliminate the seeds of the berry
