Frequently Asked Questions

Everything you need to know before you sow.

Why is Crotalaria called rattlebox?

The name refers to the dry seed pods, which can make a rattling sound when mature seeds move inside.

Can rattlebox add a bright yellow accent to a border?

Yes. Its yellow pea-like flowers provide a strong warm color that can contrast with green foliage and cooler-colored flowers.

Should children or pets be kept from eating rattlebox seeds?
Yes. Crotalaria species can contain toxic compounds, so do not ingest the seeds or plant parts and keep them away from children and pets.

Can rattlebox be grown in containers?
Container suitability depends on the species and mature size. Use a sufficiently large container with drainage and provide full sun.

How do the seed pods change after flowering?

After flowers fade, elongated pods develop and mature seeds form inside, creating the characteristic rattlebox structure.

Can rattlebox be used in a mixed flowering border?

Yes. Its upright growth and yellow flowers can provide color and structural variation when planted with compatible species.
