Persistent Spell: Natural Preservation

If your concentration a druid spell is interrupted, you can expend one use of this ability to cause its effects to linger. The spell will linger for a number of rounds equal to your Wisdom modifier, though you can end it early if you choose to. A lingering spell will end early if its maximum duration is reached before it would normally fade.

You have 3 uses of this ability, and you regain all expended uses after finishing a long rest.
