Check these first
- Assess the current light levels in your plant's location.
- Check if the stems are leaning toward a light source.
- Examine the distance between leaf nodes.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest window.
What to do: Move your plant to a location that receives full sun or very bright indirect light. If you are growing it indoors, place it directly in a south or west facing window.
Lack of Pruning
PossibleHow to tell: The plant is tall and floppy even though it has plenty of light. It looks overgrown and lacks a bushy shape.
What to do: Pinch back the growing tips in late spring to encourage branching. You can cut the stems back by 3 to 6 inches to promote a fuller, more compact habit.

When to worry
It is normal for this plant to grow tall as it prepares to bloom in late summer. Worry only if the stems are so weak they cannot support their own weight.
Stopping it coming back
Provide at least 6 hours of direct sunlight daily and prune the tips early in the season.

Questions people ask
- Can I fix a leggy plant by just moving it?
- Moving it to better light will stop further stretching, but the existing long stems will not shrink. You should prune those long stems back to encourage new, shorter growth.
- Does Blue Mistflower need to be staked?
- If it is getting enough light, it should stand on its own. If it is still flopping over, it is likely not getting enough sun.
