Rope reeds are similar to Pig tails. They can grow in all seasons, but grow more slowly and require sunlight. They are the only surface crop usable for the production of cloth. They can also be brewed into River spirits, an affordably priced drink. You may be able to collect Rope reeds of your own by gathering plants near a river or pool, but it is often easier to trade for the plants or seeds from a (non-dwarven) caravan, especially an elvish one.
To produce Rope reed cloth, the plants must be processed into threads at a Farmer's workshop. Processing plants will yield both Rope reed thread and seeds. Rope reed thread can then be woven into cloth at a Loom.
