They introduce greater biodiversity to your space and look wonderful too. Flowering herbs often have edible or medicinal uses. While in active growth, they also offer other benefits: They can be excellent companion plants for common crops, fruit trees, etc. and they can help in repelling pest species, bringing in pollinators and predatory insects to keep pest numbers down. No matter where you live, there is a wide variety to choose from. To help you get started and make your selections, here are some varieties to consider: Flowering Culinary Herbs Most of these options also have a range of medicinal uses but are also commonly used as pot herbs, for teas, or for other edible applications.

This is by no means a complete list of the flowering herbs that you could grow — there are many, many more to consider. When seeking out beautiful flowering herbs to grow, it is important to look for plants native to your area. But the brief lists above are a good place to begin. An herb spiral can create beneficial microclimates. emer1940 / Getty Images Whichever flowering herbs you choose, another consideration is where exactly to place them within your garden. You need to think about the requirements and preferences of the particular herbs in question. Growing flowering herbs in integrated ways allow them to bring their benefits to the wider ecosystem. A herb spiral can be a good idea because it allows you to create a range of habitats to accommodate a range of different herbs. Rather than simply planting flowering herbs in a dedicated herb garden, you can sow them as companion plants in a vegetable garden, mixed perennial beds or edible borders, fruit tree guilds, or forest gardens. Remember: A successful garden should be both useful and beautiful, with as many different plants and as much wildlife diversity as possible.
