What is a Hummingbird Mint Plant?
Before you start planting, it helps to know exactly what you are growing. The hummingbird mint plant belongs to the mint family, but it won’t take over your garden like regular mint. It is a clump-forming perennial, meaning it comes back year after year in the same spot.
Botanical Background
Scientifically known as Agastache, this plant is native to North America. It is often confused with other pollinator-friendly varieties, but it is distinct in its upright growth habit and intense fragrance. If you love the look of a traditional hummingbird plant, the mint variety offers a much harder, more drought-resistant option. The leaves smell like a mix of mint and anise when crushed, which also makes it deer and rabbit resistant.
Choosing the Right Location and Soil
Success in the garden always starts with location. Picking the perfect spot for your hummingbird mint plant will save you a lot of trouble later on. These plants are very forgiving, but they have a few non-negotiable needs.
Sunlight Needs
This is a sun-loving plant. To get the best blooms, you need to plant it in a spot that receives full sun. Full sun means at least six to eight hours of direct sunlight every day. If you live in an area with scorching afternoon heat, a little afternoon shade is fine. However, too much shade will result in leggy, weak stems and very few flowers.
Soil Requirements
The most important rule for soil is drainage. Hummingbird mint plants absolutely despise sitting in wet soil. If you have heavy clay soil, you must amend it. Mix in coarse sand, perlite, or small gravel to improve drainage. You can also add a little bit of compost for nutrients, but do not overdo it. Rich, overly fertile soil will cause the plant to grow too fast and fall over.
Planting Your Hummingbird Mint
Once you have the right spot picked out, it is time to get your plant in the ground. You can grow a hummingbird mint plant from seeds, but buying a starter plant from a nursery is much faster and easier.
When to Plant
The best time to plant is in the spring after the last frost has passed. You can also plant in early fall, giving the roots time to establish before winter. If you are starting from sow seeds, start them indoors about 8 to 10 weeks before the last expected frost.
Spacing and Depth
Give your plants room to breathe. Space them about 12 to 18 inches apart. This ensures good air circulation, which prevents powdery mildew. Dig a hole that is just as deep as the nursery pot and twice as wide. Place the plant in the hole, making sure the top of the root ball is level with the soil surface. Backfill the hole and press down gently to remove air pockets.
Watering and Feeding Tips
One of the best things about this plant is how drought-tolerant it is. However, young plants need a little extra help getting established.
Watering Schedule
Water your newly planted mint deeply right after planting. For the first few weeks, keep the soil evenly moist. Once the plant is established, you can cut back significantly. A good rule of thumb is to water only when the top two inches of soil feel dry. Overwatering is the fastest way to kill a hummingbird mint plant, so when in doubt, wait a day.
Fertilizing Routine
These plants are very light feeders. In fact, they often do best in poor to average soil. If your soil is completely depleted, you can apply a light, balanced, slow-release fertilizer in the spring. Avoid heavy fertilizers or fresh manure. Too much nitrogen will give you a big, beautiful green plant with very little blooms.
Pruning and Maintenance
Keeping your plant looking its best requires a little bit of seasonal maintenance. The good news is that it does not take much time.
Deadheading for More Blooms
To keep the flowers coming all summer, you need to deadhead. This simply means snipping off the spent flower spikes once they turn brown. If you leave the dead flowers on the plant, it will think its job is done and stop producing new blooms. By deadheading, you trick the plant into flowering again. Many varieties of the purple flower mint plant will rebloom vigorously with regular deadheading.
Cutting Back in Fall
As the weather cools down, your plant will start to die back. You can leave the standing stalks over winter to provide shelter for beneficial insects and visual interest in the garden. However, you should cut the plant back to about 3 to 4 inches above the ground in late fall or early spring before new growth begins.
Attracting Pollinators to Your Garden
The main reason anyone grows this plant is to bring in the pollinators. The tubular shape of the flowers is perfectly designed for a hummingbird’s long beak.
Why Hummingbirds Love It
Hummingbirds see the color red very well, making the bright orange and red varieties of hummingbird mint plant absolute magnets for them. However, the purple and pink varieties are equally attractive to butterflies and bees. If you want a garden full of life, plant a cluster of at least three to five mint plants together. This gives the pollinators a large target to find. It pairs beautifully with other nectar-rich varieties like the hummingbird flower plant.
Conclusion
Learning how to grow a hummingbird mint plant is one of the easiest ways to add long-lasting color and life to your garden. With its vibrant spikes, delightful scent, and ability to thrive on neglect, it is the perfect choice for busy gardeners. Just remember to give it plenty of sun, keep the soil well-drained, and do not overwater. Plant a few of these stunning perennials this season, and you will be rewarded with a front-row seat to the beautiful dance of hummingbirds in your own backyard!
Frequently Asked Questions
Is hummingbird mint a perennial?
Yes, the hummingbird mint plant is a herbaceous perennial. This means it will die back to the ground in the winter and return reliably the following spring in most climate zones.
Does hummingbird mint spread aggressively?
No, unlike culinary mint, hummingbird mint is not aggressive. It grows in a tidy clump and will not take over your garden beds. Some varieties may self-seed slightly if conditions are perfect, but they are very easy to manage.
Can I grow hummingbird mint in a pot?
Absolutely! It grows very well in containers. Just make sure your pot has excellent drainage holes. Use a potting mix designed for cacti or succulents to ensure the soil does not hold too much water around the roots.
Why are the leaves on my hummingbird mint turning yellow?
Yellow leaves are almost always a sign of overwatering or poor drainage. Cut back on your watering schedule immediately. Check the soil to make sure it is not holding water like a swamp, as this will cause root rot.
Do deer eat hummingbird mint?
Thankfully, deer tend to leave this plant alone. The strong, fragrant oils in the leaves taste bad to deer and rabbits. It is considered a highly deer-resistant perennial, making it a great choice for rural gardens.
How tall does hummingbird mint grow?
The height depends on the specific variety, but most hummingbird mint plants grow between 2 and 4 feet tall. Some compact varieties stay closer to 18 inches, while the giant varieties can reach up to 5 feet in ideal conditions.
