They are quite easy to grow, once received plant them in soil and they normally root in 2 weeks.
I only send old leaves which will easily root and grow new leaves very soon, sometimes they may look a bit ugly with winter frozen mark and sun burnt mark, but they are the best cuttings to grow. Some of them may flower this year, as I did some cuttings myself and they already have flower buds.
In the winter it need to be indoor or in a heated greenhouse not lower than 5 degrees.
