I take them out on the patio in the summer and put them in the sun and fertilized once a month.
I put the one you sent in a pot with the variegated ginger and it looks like it is trying to bloom or it could be a juvenile leaf coming up. It looks like a bloom stalk though. I will report if it blooms before fall and I have to bring my plants in for the winter. I have about 6 more weeks before everything has to come inside for the winter.
