Speaking of Rare

Yesterday I wrote about a rare butterfly, today a flower that’s rare in Pennsylvania.

Silverweed (Argentina anserina, formerly Potentilla anserina) is a low-growing plant of sandy soil that spreads by runners.  It’s called silverweed because the hairs on its leaves give it a silver sheen. In Pennsylvania the only place it grows is Presque Isle State Park because that’s the only location with suitable habitat.

On a worldwide basis silverweed is not rare at all.  It occurs in the northern hemisphere in Europe, North America and Asia.  It’s as wide-ranging as Iceland and Tibet.

But for us it’s a treat to see.  Dianne Machesney found only one plant at Presque Isle last Monday.

  1. Hello!

    We raised a baby chickadee. When the baby was ready to fly, we released him. for 10 days he flew to the feeder for food, but last night there was heavy rain and our baby has not arrived for the second day, I’m not sure if he can find food, before he flew for food every 30 minutes. could he die from strong wind and rain or is there another reason why he does not arrive?
