Beautiful plants! I especially like the Mikado! I find Bantels to be a bit finicky and am never sure how much water to give mine. Better to tend toward the drier side I should think. Hahnii can be cranky too if too damp for too long.

In General Sansevieria like warm to hot temperatures, bright light to full sun and to dry out some before watering. Wet and cold equals death for these plants. Though in summers heat most Sansevieria can take dampness, as long as it is hot and they are not drowning. Always acclimate any plant going outside for the summer.

Well said Sans2014. I had my Bantal's out in full rain thru summer with no ill effects. Must watch watering thru winter.
