What is this Arlene?

The photo says Magic Bells~Veranda,Lori.
Kalanchoe~Magic Bells
I found this info on the web.
A plant which originally comes from Madagascar, flowers with bell shaped flowers on a long stem for several months.

Needs a light place (south), avoid full sun in summer, water moderate 1x per week, plant food 1x every two weeks, temperature minimum 15 Celsius
Height 60 cm, width 30 cm

Looks interesting.

Yes. The flowers are hollow, very delicate and like mini hot air balloons. Most unusual.

Wow that is different for a Kalanchoe...I'm used to the little bright red or yellow ground cover plants! bell flowers really are interesting..are they always the light green? (I suppose technically they are brachts...like bougainvillea? ) Great!
