Are sennetis perenniels

Sennets, or "sennit," typically refer to a type of rope or cord made from various materials, often used in crafting or boat rigging. However, if you meant "senecio," which includes the perennial plant known as "senecio," then yes, some species of Senecio are perennial. Perennial plants live for more than two years, regrowing each season. Please clarify if you meant something else!
