Welcome back 'hawaiianeyes'! You might want to post this on the 'discussion' side of the hosta forum!
It will get more attention as the 'conversation' side tends to be kinda quiet this time of the year!

I would not describe hosta as having bulbs! Rhizomes are what they multiply from, I'm thinking, but maybe
others on the 'other' side can give you a more technical answer! :o)

Do come back to this side, though--we can use the attention! We get kinda lonely here, as I said, 'this
time of the year'! :o)
