List of the Best Hyssop Companion Plants

1. Bee Balm

Bee Balm is a striking flower with vibrant colors. They come in scarlet, pink, white, purple, and lavender shades.

These colors make a beautiful contrast with the popular anise hyssop or the Agastache foeniculum, scientifically. This beautiful combination alone is a good reason to plant bee balms in your garden.

– Characteristics

An advantage of deciding bee balm as a companion plant for hyssops is their long blooming season. These native North American wildflowers bloom for longer, almost the same as hyssops. Thus, you will have life in your garden for many months.

Over 15 different species of this flower are commonly sold in stores, so you have plenty of room to make your choice. The plant also does not grow very tall and is more of a ground cover. Their colorful carpet of flowers would do well to add interest and appeal to your garden.

Their foliage is not something out of the ordinary, which is a good thing in this context as it will not overshadow the original residents of the garden and add to the beauty of the overall scene. These plants are also hotspots for gathering bees, birds, hummingbirds, and songbirds.

Bee balm is ideally grown in spring or fall. It is a perennial plant that grows quite quickly to the point that it will bloom in its first season. When you plant these, you won’t wait long for the flower to bring forth its vibrancy. Also, there are plenty of plants that go with Bee Balms.

– Growth Requirements

Bee balms like to grow in moist and rich soils. They prefer soils that are neutral to acidic in nature. Although bee balms can survive in the shade, they grow to their full potential under full sunlight so plant them in an area with proper exposure to the sun.

Bee balms love water and prefer regular watering sessions. They are among the few plants that thrive in damp soils with the risk of root rot. Thus, provide them with plenty of water.

2. Rosemary

Rosemary is another excellent companion plant option for all hyssop varieties. Rosemary is native to the Mediterranean region. Their leaves and oil are essential components for medical and culinary purposes.

For medical uses, rosemary is good for hair growth, and rosemary extract can be used as a sunblock.

– Characteristics

In the world of cuisines, rosemary is used primarily for its flavor. It is used as stuffing in roasted lamb, chicken, and turkey. The leaves can be used to make herbal tea. They are also cooked alongside meats and vegetables to give the dish a strong aroma. Growing rosemary in your garden will provide you with the opportunity to try new dishes right at home.

The culinary benefits are not the only ones that rosemary will introduce to your garden. They are also a great way to enhance the visuals of your garden.

The plants have straight stems filled with thin, needle-like leaves that are gray-green in color. The herbs would also produce tiny white or light blue flowers that are a beautiful sight every time to enter your garden.

Rosemary is a low-maintenance plant. It requires trimming, especially after the flowers bloom, to encourage growth. You can replant these trimmings to grow more plants instead of throwing them away. This characteristic will help you propagate the growth of your plants without much hassle or the need to buy more seeds.

– Growth Requirements

Rosemary prefers moist but well-draining soil. They also like soil that ranges from acidic to neutral in nature. Well-lit places are the best ones to grow rosemary as they require abundant light. They do not tolerate shade, so keep this in mind when planting your seeds.

These herbs have good drought tolerance once it is mature but requires water during its growth, but water logging is very dangerous, especially for young plants. It is better for the plant to be under-watered compared to over-watering.

3. Lavender

Lavender plants are a great option for companion planting with hyssops. These gorgeous purple herbs are famous for their sweet fragrance.

Lavender Blossoms PlantAmerica

They produce beautiful spiky flowers that are typically purple and have gray-green foliage. These plants would even grow in the form of shrubs and come back to life every year to bless us with their signature fragrance and vibrant flowers.

– Characteristics

Lavender is a native plant in Europe, but that does not stop it from growing in other parts of the world without significant problems. They are not the fastest-growing plants either and typically grow moderately. They mature when they reach a height of about three feet and a spread of four feet.

You can plant this flowering shrub in early spring when there is no threat of snowfall and the soil has warmed up. They can also adapt to many growing conditions but do well in warmer climates and enjoy light exposure. Lavender would also make excellent companion plants to many flowers typically found in a garden.

Your experience with growing this sweet-smelling shrub will depend on the conditions you provide and the variety you choose.

If you take good care of lavender plants, they do well for a couple of years, but generally, they do not have a very long lifespan. Even if they are kept in ideal conditions, they wither away in about ten years.

– Growth Requirements

Some lean soil that is moist but drains well is the best option for growing lavender plants. You can add some sand to the soil mixture to increase drainage. Alkaline soil will encourage more fragrance in your plants, while acidic soils may result in short lives for the plants.

Lavender plants enjoy their time under the full sun. This exposure will result in abundant flowers that are big and lush, and they would also thrive and release their aroma into the air and keep the pests away.

Lavenders are drought-resistant plants, but they need water during their early growth. Ensure they receive enough water in their early days, but once they are established, they can survive extended periods without water.

4. Black-Eyed Susan

The Black-eyed Susan or the Rudbeckia fulgida, is a tall flowering plant that combines very well with hyssops as its companion plant. It has the ability to grow up to three feet tall. It has rigid stems that can be an excellent support for other plants in the garden.

Not only that, but it is called “black-eyed” because of the dark brown center of its flower head.

– Characteristics

In addition to being the support structure, these flowers attract beneficial pollinators such as insects and birds. As the one mentioned above, this accelerated pollination helps the propagation of other plants in the garden. This will help keep your garden residents to keep thriving and spreading.

The Black-eyed Susan is a beautiful flower that produces yellow-orange daisy-like flowers. The description alone is enough to visualize its beauty. These flowers have a brown centerpiece. These yellow blooms contrast sharply with hyssops as their companion, enhancing the scene’s overall beauty. The different colors make the scenery more vibrant.

This plant thrives under the full sun. It can also live under the partial sun, but its bloom would not be to its full potential. In addition to partial shade, this plant can also tolerate harsh conditions such as bad soil and water. But naturally, the flowers will not be able to bloom with their full brilliance.

– Growth Requirements

Black-Eyed Susan grows best in rich, loamy, moist, and well-draining soil. It is also best to use a soil mixture that is neutral in nature. You can always send your garden soil for testing before any actual planting.

These daisy look-alikes would also grow to their best potential in full sun as it will help the plant to thrive and produce abundant flowers. The only exception that you have is if you live in hot and dry climates, as that can lead to damage from burning.

The best watering conditions are to keep the soil moist without making the ground soggy, which can lead to root rot. They may require more water depending on the weather and dry conditions. The rule of thumb, in this case, is to ensure one inch of water per week.

5. Coneflowers

Coneflowers are hardy perennial wildflowers native to North America. Related to the daisy family, their flowers shoot up above the leaves near the base on straight, upright stalks.

Their blossoms are characterized by their dropping petals around a slightly raised, cone-shaped center at the stalk’s tip, which contains smaller, fertile flowers.

– Characteristics

There are wide varieties to choose from, and the colors of petals vary between the different cultivators, from red, purple, yellow, and all shades in between. This makes it easy to mix and match with the hyssop’s colors.

Their fertile flowers near the center cone attract many pollinators and have medicinal properties. They are also deer-resistant, and while they have a honey-like fragrance, they remain susceptible to certain pests. This is easily remedied if you plant hyssop alongside them, and together they secure the surrounding plants from many live hazards.

Coneflowers are hardy and low-maintenance as they are drought-tolerant. They are generally rated for USDA hardiness zones three to eight, prefer full sun, and thrive in well-draining, moderately fertilized soil if it is not wet. This means they are not a good choice if it rains a lot where you live.

– Growth Requirements

Coneflowers thrive in moist, nutrient-rich, and well-draining soils. Damp and soggy soils can be fatal for these plants, which means that you must make sure that you do not overwater them.

If you want your dahlias to produce healthy and abundant flowers, plant them in an area with plenty of sunlight to help them grow.

Even though they are drought-tolerant, they do require regular watering early stages. When they have matured, they will only need water if there are signs of drought.

6. Alliums

Alliums make a great companion plant for hyssops. These colorful plants are related to onions, which is unconventional as most of us will not think of onions as ornamental plants in a garden. But this pompous plant produces vibrant flowers that greatly contrast the the hyssops.

Blooming Purple Alliums PlantAmerica

Hyssops and alliums produce brightly colored flowers that translate to a vibrant scene in your garden. Both plants have uniquely shaped flowers. The flowers of alliums are like onions, and the flowers produced by hyssops are elongated clusters of many tiny blossoms at the top of the stem.

– Characteristics

Alliums grow to a decent height with tall stems that bear flowers at the top. These thin stems do not have a lot of foliage, making the scene under the plant a little lacking luster. This can be remedied by adding hyssops that grow to almost the same height but have comparatively denser foliage, resulting in a better-looking scene.

On top of the visual benefits, this companionship is also very easily maintained. Alliums are tough and hardy plants that do not require a lot of hassle to grow. They are tolerant to both cold and droughts and are not bothered by pests, rodents, and other wildlife like deer that may threaten other plant life. Furthermore, there are wide varieties for you to choose from.

– Growth Requirements

Alliums can quickly get accustomed to all types of soil as long as they are well-draining. Waterlogged soil is dangerous for these plants. Providing them with slightly acidic soil is a plus.

If you want to see an abundance of vibrant, colorful flowers, you will do well to plant alliums at a location that receives plenty of sunlight. However, they can grow in partial shade as well. Alliums do not require a lot of watering, and if you live in a rainy area, that would be more than sufficient to meet their water requirements.
