Sansevieria cylindrica
... two mother plants from my own collection, used for (side shoot/leaf) propagation; this/next year there will certainly be 1-2-3 new side shoots/plants (these can be divided if you want); elegant dark green leaves, leaf length up to 70-100cm, not over-fertilised, slow-growing (with the growth pause in winter), not winter-hardy; in self-mixed well-drained substrate (repotting only desired in 1-2years); for a bright/sensible location; avoid waterlogging. ..
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 simply look natural. Sansevierias are not hardy, as plants are supposed to clean the indoor air and increase the oxygen content in the house. Enjoy your new Sansevieria cylindrica!
