fertilizeing will keep them blooming well& also when it gets real hot like TX hot july/aug.mine usually don't bloom then& also bloom in cooler weather better.they are perienals,but are frost tender and a freeze will kill your plant
in Indiana(I use to live Indpls)you can bring indoors durring the winter.They do produce seed
is best done fresh and needs light to germinate and are low on germination.they do best when temps are about 70-75.
The one in the bucket...you can put into a larger bucket...or split the plant
and divide it between the buckets.
