Green thumb is wanted... Leaf cuttings (10cm each) from your own mother plant from my Sansevieria collection, a new side shoot/plant will come within 1year if well cared for - patience is called for!, to be planted in the permeable organic substrate (immerse 3-4cm into the substrate); try your hand and grow your own Sansevieria cylindrica (in about 5-10years you will then have the beautiful mother plant - like mine - according to the picture - this one is not for sale). 

All my Sansevierias from my collection (over 100 species) grow slowly, without being massively fertilised, with the growth pause in winter. As a result, they are top healthy, robust and just look natural. Sansevierias are not hardy, as plants are supposed to clean the indoor air and increase the oxygen content in the house.
