Will the curled leaves flatten out again?

Why are my bog stitchwort leaves curling? Causes and fixes

Check these first

Inspect the undersides of the leaves for small insects.
Touch the soil to ensure it is still damp.
Check if the plant is getting direct afternoon sun.

Likely causes

Aphids
Most likely
How to tell: You will see small green or black insects clustered on the tender new growth or the undersides of leaves. They suck the sap, causing the foliage to twist and curl as it develops.
What to do: Spray the plant with a gentle stream of water to dislodge the bugs. If they persist, apply insecticidal soap once a week for 3 weeks until they are gone.
Heat Stress
Possible
How to tell: The leaves curl inward during the hottest part of the day when the plant loses moisture faster than it can take it up. The plant usually looks better in the evening or early morning.
What to do: Move your plant to a spot with partial shade during the afternoon. Ensure the soil remains consistently damp by checking it every 2 days.

When to worry

Worry if the curling is accompanied by yellowing or stunted growth that does not recover overnight. It is normal for the plant to look slightly wilted if it is temporarily dry, but it should perk up quickly after watering.

Stopping it coming back

Keep your plant in a cool, humid spot and check for pests every time you water. Consistent moisture helps the plant stay strong enough to resist minor pest attacks.
