Do I need to prune it to make it flower?

Pruning does not directly trigger flowers, but it helps keep the plant compact. Focus on light and temperature instead.

What color are the flowers?

Solanum etuberosum typically produces lovely star shaped flowers that are often white or pale purple.

Why is my Solanum etuberosum not blooming? Causes and fixes

Check these first

Assess if the plant is getting at least 6 hours of bright indirect light.
Ensure the plant is not being over-fertilized with high nitrogen, which promotes leaves over flowers.
Check for pests like aphids that might be sapping energy from the plant.

Likely causes

Insufficient Light
Most likely
How to tell: The plant looks leggy or stretched out toward the nearest light source. It lacks the energy to produce buds.
What to do: Move your plant to a spot with bright indirect light. If your home is dim, consider using a grow light for 10 to 12 hours a day.
Lack of Seasonal Cooling
Possible
How to tell: The plant looks healthy and green but never sets buds. It may need a slight drop in temperature at night to trigger blooming.
What to do: Try keeping the plant in a slightly cooler room at night during the late winter. A drop to 55 or 60 degrees Fahrenheit can sometimes encourage flowering.
