Garden Update: Pool Garden

I am probably most disapointed by the pool garden. The purple heart is taking over and getting leggy. My bananas are still turning yellow and my cannas are starting to have a yellow tinge, too. The cannas are blooming however, as well the hybiscus, which you can just barely see in the middle of the picture. The above plant is very dependable to look beautiful on even the hottest days. I thought it was called portaluce, but I must be spelling it wrong because I can't find anything on the Internet.
