My begonia pot is sprouting . . . LETTUCE?!?

Hey y'all.  Been away for awhile. A reaction to new chemo.  But I am back now.

While indisposed I decided to try something I saw online.  The theory is that a root end of a romaine lettuce will sprout a new head.  Apparently they were right.

I planted the root end in the begonia pot on my kitchen window sill.  Twelve hours later these little leaves jumped up.  I love it when an online hack really works!

More pictures coming as it progresses.  I really hope the begonias don't mind! They are so healthy right now. Even blooming.

I'll get another pot and some soil next pay day. Maybe a large enough pot to add more lettuce ends.
