Hello Touchet - These are very aggressive growing plants when they are in their ideal environment (partial sun with plenty of water). Although we cannot give a good estimate on growth per month, we do know that often the case with equisetum is keeping the plant in one area vs containing it. When they are delivered they are about 1 to 1.5 feet tall. For a quicker fill I would order (4) for the container you have mentioned. Thank you - National Plant Network
Hello Grace - this will grow from 1-2' tall and can spread up to 6'. Because of the aggressive spread nature of this plant, we suggest planting in containers and then placing in ground. Thank you - National Plant Network
Hi SS - these can grow up to 16-18" Tall. Thank you - National Plant Network
Hi Dale - you have to remove the area with it including the roots. Thank you - National Plant Network
Hi Nick - Yes two each would be fine. They will dry up and no they will not be messy on the couch as they are twigs that don't produce any type of flowers. Thank you - National Plant Network
There are numerous reeds in the 2.5 quart pot. Some of the online sellers are just selling seeds or a few baby reeds.
Hi CherylBoone - there are about 15-20 rods/branches. Thank you - National Plant Network
