To remove any confusion, you cannot actually accept this quest and the area will not show up on the map.
You need to collect all 20 High-Fiber Leaf by Killing all of the lashers in the area surrounding /way 30 52
(the drop rate isn't too bad, so it will take about 15 minutes).
Then return to Initiate Radiya. at /way 56 77

Got plenty of [item=192658] while doing the side quest chain, "Gardens of Unity" in Thaldraszus, which starts with A Hand in Cultivation leading to Azeroth Pest Control. (not sure if first quest, A Hand in Cultivation, is required but it does have nice garden tool mogs as a reward choice.) [item=192658] drop from [npc=187687] which are pretty abundant and easy to kill. (Note: you can also just go there and kill the seedlings, they are not special quest-only mob: /way Thaldraszus 39 74). (Quest chain is also worth doing for the beautiful pet rewarded at the end, [item=194098].)
