Petco plant bulbs

Has anyone tried these and what did the plants end up looking like? Any special care outside of just dropping them into the water and waiting?

Quote from Avery

Many people have had luck in just dropping them into the tank and watching to make sure that they do not rot. Others have had luck treating them as a seed and putting them into the fridge, before putting them into the tank and trying to bury them in the substrate to act as if they were above water in a sense.

Thank you I am going to give it a shot!
