Rosemary topiaries are widely available now from nurseries, garden centers, big box stores, and grocery stores.
They make an excellent seasonal display, provide fragrance and decor for the table top inside or in a container outside.
If kept outside, protect from freezing the first year. Potted rosemary can easily dry out. Keep an eye on this. That shouldn’t be a problem since you will be going by often for a snip for cooking.
