Will the brown tips turn green again?

No, the brown tissue is dead and will not recover. You can trim the tips for aesthetic reasons if you like.

Does tap water cause brown tips?

Sometimes, the minerals in tap water can build up in the soil and cause tip burn. If you suspect this, try using filtered or rainwater for a few weeks.

Blue vervain: brown tips, causes and fixes

Check these first

Check the soil moisture to see if it has dried out.
Observe the environment for nearby air vents or heaters.
Feel the texture of the brown tips to see if they are dry or mushy.

Likely causes

Inconsistent Watering
Most likely
How to tell: The tips turn brown and brittle while the rest of the leaf looks dull. This happens when the plant experiences cycles of extreme dryness followed by heavy soaking.
What to do: Stick to a strict watering schedule every 2 to 4 days. Use a moisture meter or your finger to ensure the soil stays damp at all times.
Low Humidity
Possible
How to tell: The tips crisp up even when the soil is damp. This is common in indoor environments with forced air heating or cooling.
What to do: Place the plant on a tray filled with pebbles and water to increase local humidity. Avoid placing the plant directly in front of air vents.
