There are a few different ways to describe a plant just starting to grow, depending on the stage of development:

* Seedling: This is the most common term for a young plant that has just sprouted from a seed. It typically has a small root system and a few leaves.

* Sprout: This is a more general term for a new shoot or growth emerging from a seed or bulb.

* Sapling: This refers to a young tree, typically smaller than 10 feet tall.

* Shoot: This is a general term for any new growth on a plant, including stems, leaves, and flowers.

The specific term you use will depend on the context and the stage of development of the plant.
