Adjust Spacing as Needed: Depending on your specific landscape conditions and aesthetic preferences, you can adjust the spacing between Mexican Heather plants accordingly. If you prefer a more densely planted look, you can space the plants closer together. However, be mindful not to overcrowd them, as this can lead to competition for resources and reduced airflow, which may increase the risk of disease.

By spacing Mexican Heather plants appropriately at planting, you can create a visually appealing landscape design while allowing each plant to thrive and reach its full potential. Proper spacing also facilitates maintenance tasks such as watering, pruning, and fertilizing, ensuring the long-term health and vitality of the plants.

Mexican Heather is typically grown as an annual or tender perennial in most climates. In warmer regions where temperatures remain mild throughout the year, Mexican Heather may behave as a perennial, persisting and flowering year after year.

However, in regions with colder winters or freezing temperatures, Mexican Heather is often treated as an annual or tender perennial, as it may not survive the winter outdoors. In these areas, Mexican Heather is commonly grown as a bedding plant or container plant during the warmer months and replaced each year.

In summary, while Mexican Heather can exhibit perennial behavior in frost-free or mild climates, it is often grown as an annual or tender perennial in regions with colder winters. It's essential to consider your local climate and growing conditions when determining the longevity of Mexican Heather in your garden.

Mexican Heather is native to warmer regions and is generally considered frost-tender. While it can tolerate light frosts and cool temperatures for short periods, prolonged exposure to freezing temperatures can damage or even kill Mexican Heather plants.
