Do aphids hurt the plant?

Yes, they suck the sap from the plant and can cause the leaves to curl and the flowers to look stunted. It is best to treat them as soon as you see them.

Will my plant flower if the leaves are curled?

If the curling is caused by aphids, the flowers might be affected. If it is just heat stress, the plant should bloom normally once it gets enough water.

Rough hawkbit: curling leaves, causes and fixes

Check these first

Check if the soil is dry to the touch.
Look closely at the undersides of the leaves for tiny insects.
Observe if the curling happens only during the hottest part of the day.

Likely causes

Heat Stress
Possible
How to tell: The leaves curl inward during the hottest part of the day to reduce surface area. They usually flatten out again once the sun goes down.
What to do: Give the plant a deep watering if the soil is dry. If the heat is extreme, provide some light shade during the mid afternoon.
Aphid Infestation
Possible
How to tell: You will see tiny green or black insects clustering on the flower stalks or the undersides of leaves. The leaves may look distorted or curled where the aphids are feeding.
What to do: Spray the plant with a strong stream of water to knock the aphids off. For a persistent problem, use an insecticidal soap once a week.

When to worry

Stopping it coming back

Keep the plant consistently watered during hot spells and inspect the flower stalks regularly for early signs of aphids.
