How long does it take in the Sims 4 to grow a cow plant?

In The Sims 4, it takes approximately 7 Sim days for a cowplant to grow from a seedling to a fully grown cowplant. After planting the cowplant berry, you'll need to ensure it is watered and cared for to reach maturity. Once fully grown, the cowplant can be fed and will eventually be able to interact with Sims.
