Frequently Asked Questions
Will a selected parent type bloom in the exact pictured color?
No. Seedlings can vary. The image and selector identify the parent reference, not a guaranteed flower color or clone.
Is this tropical hibiscus?
No. This listing is presented as seed from the hardy hibiscus group, which behaves as an outdoor perennial in suitable climates.
When will hardy hibiscus return in spring?
Hardy hibiscus often emerges later than many perennials. Mark the planting location and allow time for the soil to warm.
Does it need wet soil?
It performs best with consistent moisture, especially in full sun, but the site should not remain stagnant or poorly aerated.
Are the plants deer-resistant?
No deer-resistance claim is made. Browsing pressure varies by location.
