  Hi @Lynn142 That is known as 'Cuckoo spit' and is a protective foam exuded by 'Froghopper' insects:

  They don't cause any significant damage.
  

  
  

  A trowel in the hand is worth a thousand lost under a bush.

  What we called Cuckoo Spit as children. Inside youll find an immature frog hopper insect.

  Nothing to worry about providing it’s not on a recently imported plant.
