Frequently Asked Questions
Is Larkspur safe to plant where pets or kids play?
No — all parts are toxic, containing ranunculin and other alkaloids that cause gastrointestinal upset and potentially serious toxicity if ingested, so keep it out of reach.
Will my Larkspur come back next spring on its own?
Often yes — it prefers cool spring weather and re-seeds itself readily, so volunteer seedlings frequently return the following year.
