No birds today. Flowers, instead!
Since the aviary at the zoo is replicating a tropical forest, it is also planted with 60 different plant species from tropical areas all over the world. One of the plants that was blooming this past Saturday was an Amazon Lily. It can be grown in Zones 10-11, or the extreme southern areas of states such as Florida or can be kept indoors in all other zones.
I read at Plant Files that one woman has had an Amazon lily plant since the 1950's, so it seems to be an extremely long-lived plant under the right conditions.
