- **Species:** Several species belong to this genus, including *Amsonia tabernaemontana*, *Amsonia hubrichtii*, and *Amsonia ciliata*.

### Physical Characteristics:
- **Flowers:** The flowers are small, typically pale blue, and star-shaped with five petals. They grow in clusters at the tips of the stems.
- **Leaves:** The leaves vary depending on the species, but they are usually narrow, lance-shaped, and bright green, turning yellow in the fall.
- **Height:** Bluestar plants can range from about 1 to 3 feet in height, depending on the species.
- **Growth Habit:** They have a clumping growth habit, forming dense mounds of foliage.

### Growing Conditions:
- **Sunlight:** Bluestars thrive in full sun to partial shade.
- **Soil:** They prefer well-drained, moderately fertile soil. They can tolerate a range of soil types, from sandy to clay.

- **Wildlife:** They attract pollinators like bees and butterflies but are generally deer-resistant.

### Maintenance:
