Olsen’s News:

Do you recognize this plant?

We recently gave a talk to the Mount Sinai Garden Club on Under Appreciated Perennials. We thought you might be interested too!

April’s Highlighted Plant is Helleborus, or Lenten Rose. Come learn about this wonderful, spring blooming perennial and let us help you answer the question ‘Does this belong in my garden?”

Helleborus ‘Pink Frost’ and froggy friend.
