As per Doddler's ROFuture Wiki:
QUOTE
Plant Cultivation
Plants will die out automatically after 5 minutes from being summoned.
01/08/2007 - Implemented on kRo Sakray and Main.
Granted "Die" is the wrong term used. The plants will "despawn" similar to that of the plants summoned with the alchemists "Summon Flora" skill. Plants that have been Polymorphed will also despawn when their 5 minute timer has expired. iRO's "Sakray" test server got this update with the 11.2 patch.
The next change is one Doddler did not list. You may only summon ONE plant with Plant Cultivation PER CELL. No more stacking them. They can still be stacked however with skills that push, ie: Cart Revo. Bowling Bash, Arrow Repell. iRO Sakray received this update shortly after kRO, or at the same time.
