However, because successful growth depends on various factors beyond our control—such as planting conditions, weather, and care—we cannot offer refunds for seeds, corms, or bulbs that do not germinate or sprout.

Thank you for your understanding and support. If you have any questions about planting or care, we’re happy to help!
