Expert Response
The foam on your plant is caused by spittlebugs. The nymphs use the foam to hide in. Spittlebugs do very little damage to plants and the nymph stage is short lived. The least invasive method of removal is to use a hose to spray them off. Below is a link with information about spittlebugs.
