Some cultivars, the lavendins, are sterile. Lavender can drop seed if the seedheads are allowed to dry on the stems and not harvested. The seeds are slow to germinate, however. The best way to reproduce lavender is by cuttings.

I think it is overwatered. The container looks too big for a small plant. When there is excess soil, it holds more water than the plant needs. Only go up one pot size when repotting a plant.

Since it is so crumpled over, it's hard to tell what it is, but I'm leaning toward lavender or gray Santolina (lavender cotton).

You can get your soil tested and it will give you the pH level and what nutrients need help.
Also, lavender needs soil similar to cactus and succulent soil. They need a dry, sunny disposition. I would add sand to your mix. At least 25 percent.

If you think it is still alive, cut it back close to the ground. It should regrow. I find lavender is very hard to grow. Mine never live very long even though I take care not to overwater them.

This could be a "sport" or a plant mutation. Here is more:

Generally, you will wait until the second year to prune. Cutting spent blooms right below the flower can help to reorient some of that energy to the right places, also.
