Fasciation on Alnus glutinosa Some two weeks ago we noticed this fasciation on new shoots coming from a stump that had been cut short last year. At first we thought it was on Willow as a branch of Willow from the other side of the ditch was sticking through the shoots of Alder, but it turned out to be in fact a stump of European Black Alder (Alnus glutinosa). Fasciation on Willow is much more common, but on Alder this is quite a rare find, or so we were told.

    1. Lots of shoots with 2-4 fasciated "twigs" on the same stump, but this one shoot was really extreme indeed :o) Posted one month ago, modified one month ago
  2. That's really cool! I've only seen fasciation a couple times...in Echinacea flowers. Posted one month ago

      1. I don't know...I think this is pretty awesome. It looks like strands of spaghetti that got stuck together. Posted one month ago
  3. A phenomenon with a most bizarre physical outcome. This is an amazing example here, thank you. Posted one month ago

''Alnus glutinosa'', the common alder, black alder, European alder or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium ''Frankia alni'' enables it to grow in poor quality soils.
