Caladiums are typically not grown from seeds as they are primarily propagated through tubers or corms. However, if you do manage to obtain caladium seeds, it's important to note that they can be challenging to germinate and require specific conditions. Under optimal conditions, it can take several weeks to a few months for the seeds to germinate and develop into small plants. It's worth considering that growing caladiums from seeds is a longer and more unpredictable process compared to using tubers for propagation.
