Really impressive! I have never seen new bulbs sending shoots in the same season they were formed.
Winters are not very cold in here, but all the new bulbs of L longiflorum always wait for the next season to send shoots, no matter what I do.
I read that in Hawaii they keep growing continuously:
"Some require special treatment--for me, L. longiflorum needs a dry rest in August-September, or else it will keep growing from the top of the stem (Make a bulb in the air and keep growing) and never flower."

Do all the tropical lilies behave this way?
What happens with the new bulbs of your pics if you let these shoots grow and then they freeze in winter?
