Materials - plants | Crafting Guild Wars 2 Guide
Last update: 11 May 2016
Collecting the plants is more time consuming. Because of big number of its species and a fact that some of them may be found in the particular regions of the world, it's hard to put them into the chart. It's more simpler to remember one rule: to get a plant, use a sickle on the similar level like mining pick and axe in the particular location. If there's a plenty of iron ore, you'll get all available crops using the iron harvesting sickle. There are some exceptions, mainly in regions with required level about 70-80. In such cases you should have a spare orichalcum sickle.
Because there is a plenty of iron, it's enough to use the iron sickle.
During travelling you may find so called farms. They contain few identical materials and respawn every 23 hours.
The last place where you can buy cook's ingredients are merchants. In every city you can find karma vendor, who'll sell you herbs for few karma points. To get more rare items you can also visit heart vendor(available after completing the mission). Some of them offers the plants.
