It will adjust eventually, but it will require more time and attention than plants that have already gone through this.
One last tip: when buying aquarium plants, look for places that sell plants that have been grown submerged underwater (hint: you're on the site for someone who does that). Plants that have been grown above water or only partially submerged go through an adjustment period to fully underwater life, and they look pretty ugly in the process due to something called melting. Melt involves plant leaves dying and dropping off as the plant adapts to its new environment. It will adjust eventually, but it will require more time and attention than plants that have already gone through this. Some plants will still melt even if they've been grown submerged ( Vallisneria is notorious for this), but overall, you'll have better luck with submerged growth.
