Sansevieria - grow in glass vase with rocks?
We went to a restaurant recently and each table had a glass vase approx.6" tall and a diameter of about 4". The glass "tube" was filled about half way with 1/2" river rocks and the Sansevieria (about 6" tall with 7 or 8 architectural leaves) was placed into it without any soil and the roots were fairly well dispersed into the rocks. The water was only about 2" deep leaving quite a few of the roots exposed to the air and were clinging to the rocks.
Is this just a method for short term display of this houseplant in the restaurant or can we do the same at home and make it grow that way?
Thanks in advance for your help. Just found this web site / forum and thrilled to be a part of it. There's so much to learn and share here.
