Should I prune back leggy stems?

Yes, cutting back leggy stems by one third will encourage the plant to grow back bushier. Do this in late spring to keep the shape compact.

Will it bloom if it is leggy?

Leggy plants often produce fewer flowers because they are putting all their energy into stretching for light. Improving the light will help it flower better.

Why is my Sneezewort growing so leggy? Causes and fixes

Check these first

Observe how many hours of direct sun the plant gets each day.
Check if the plant is being shaded by taller nearby shrubs.
Inspect the stems for signs of stretching.

Likely causes

Insufficient Light
Most likely
How to tell: The stems will look thin and pale while reaching toward the nearest light source. You will notice large gaps between the leaves on the stem.
What to do: Move your plant to a spot that receives at least 6 hours of direct sun daily. If you are growing it indoors, place it directly in a south facing window.
Excessive Nitrogen
Possible
How to tell: This is less common for this plant, but usually happens if you over fertilize with high nitrogen products. The plant grows too fast and becomes weak.
What to do: Stop using high nitrogen fertilizers immediately. Switch to a balanced, slow release fertilizer once in early spring.
