Obligatory comment to avoid planting Asclepias curassavica (aka tropical milkweed, often found in big box stores), in favor of any of the native species.

For the healthiest to butterfly option, your milkweed should die back yearly in whatever climate you plant it.

This helps encourage butterflies to migrate at the appropriate time and prevents parasite load from building up.

Alternatively, you can cut it back yearly... but safer to just get ahold of a local species.
