Different Types Of Chrysanthemums – Choosing The Perfect Bloom
I know that feeling when the summer heat begins to fade and your garden starts looking a bit tired. You want a burst of color that can withstand the cooling nights and keep your outdoor space vibrant well into November.
If you have ever felt overwhelmed by the sheer variety at the nursery, you are not alone. There are so many different types of chrysanthemums available that it can be tricky to know which ones will actually thrive in your specific garden beds or patio pots.
In this guide, I am going to walk you through the various classes of mums, explain the difference between hardy and florist varieties, and share my personal secrets for keeping them blooming longer. You will leave here ready to transform your landscape into an autumn masterpiece.
The Essential Distinction: Garden Mums vs. Florist Mums
Before we dive into the specific flower shapes, we need to talk about the most common mistake beginners make. Not all mums are created equal when it comes to surviving the winter.
Garden mums, often called hardy mums, are true perennials. They produce underground stolons, which allow them to survive freezing temperatures and return year after year if planted early enough in the season.
Florist mums, on the other hand, are usually grown in greenhouses and sold as gift plants. They lack the root structure needed to survive a cold winter and are best treated as short-lived indoor decorations or temporary annuals.
If you want a plant that returns next spring, always check the tag for hardiness zones. Most garden varieties are happy in zones 5 through 9, but they need time to establish their roots before the first hard frost hits.
Understanding the different types of chrysanthemums and their unique traits
When you start looking closer at these flowers, you will notice they aren’t all just “round mounds.” The National Chrysanthemum Society actually recognizes 13 distinct classes based on flower shape and petal arrangement.
Each of these different types of chrysanthemums offers a unique texture for your garden. Some look like delicate daisies, while others resemble exploding fireworks or perfectly round velvet cushions.
Choosing the right class depends on your personal style and where you plan to plant them. Let’s break down the most popular categories you are likely to encounter at your local garden center or in specialty catalogs.
The Classic Pompom Mums
Pompom mums are exactly what they sound like. They produce small, stiff, globe-shaped flowers that are densely packed with petals. They are a personal favorite for borders because they hold their shape so well.
These blooms are typically small, usually under four inches in diameter. Because the petals are so tight, they are remarkably durable against wind and light rain, making them a sturdy choice for exposed garden beds.
If you love creating floral arrangements, pompoms are a must-grow. Their stems are strong, and the flowers have an incredible vase life, often lasting two weeks or more after being cut.
Elegant Spider Mums
Spider mums are the showstoppers of the chrysanthemum world. They feature long, tube-like petals that end in a hooked or coiled tip, resembling the legs of a spider.
These are often found in exhibition gardens because they look so exotic. However, they can be a bit more delicate than the standard garden mum. They may require staking because the large flower heads can become heavy.
I recommend planting spider mums in a spot protected from heavy winds. Their long, thin petals can get damaged in a storm, but their unique look is well worth the extra bit of care and attention.
Bold Decorative Mums
Decorative mums are the ones you see most often in “fall porch” displays. They have a flat appearance with petals that get longer as they move toward the outside of the flower head.
The center of the flower is usually hidden by the petals, giving it a very full, lush look. They come in almost every color imaginable, from deep burgundies to bright, neon yellows.
Because they grow in a naturally mounded shape, they are perfect for large containers. Just remember to give them plenty of water, as their dense foliage can prevent rainwater from reaching the soil in the pot.
Delicate Single and Semi-Double Mums
If you prefer a more natural or “wildflower” look, single and semi-double mums are the way to go. These look very similar to daisies, with a distinct central disk surrounded by one or more rows of petals.
These varieties are fantastic for pollinator gardens. Bees and butterflies have a much easier time reaching the nectar in these open-faced flowers compared to the dense pompom or decorative types.
They bring a light, airy feel to the autumn garden. I love pairing these with ornamental grasses to create a soft, flowing landscape that catches the low autumn sun beautifully.
Intriguing Anemone Mums
Anemone mums are a bit like a hybrid between a single mum and a pompom. They have a ring of flat outer petals, but the center is a raised, cushion-like mound of tiny tubular florets.
The center “cushion” is often a different color than the outer petals, creating a stunning two-tone effect. They add a sophisticated touch to any garden bed or floral bouquet.
These are generally quite hardy and easy to grow. They provide a nice middle ground for those who want something more interesting than a daisy but less “stiff” than a pompom.
How to Select the Best Variety for Your Garden
Choosing from the different types of chrysanthemums involves more than just picking a color you like. You need to consider the bloom time and the growth habit of the plant.
Mums are categorized as early, mid-season, or late bloomers. If you live in a northern climate with early frosts, you should stick to early-blooming varieties to ensure you actually see the flowers before the snow flies.
In warmer southern climates, late-blooming mums are a treasure. They provide color well into November when most other plants have gone dormant for the winter.
Also, consider the height. Some varieties stay under 12 inches tall, while others can reach three feet. Always place taller varieties at the back of your border so they don’t overshadow your smaller plants.
The Secret to Success: Planting and Soil Requirements
Mums are sun-worshippers. To get those tight, flower-covered mounds we all love, you need to provide at least six to eight hours of direct sunlight every day.
If you plant them in the shade, they will become “leggy.” This means the stems grow long and weak as they reach for the light, and they won’t produce nearly as many flower buds.
The soil is equally important. Mums have a shallow, fibrous root system that hates “wet feet.” They need well-draining soil rich in organic matter like compost or aged manure.
If your soil is heavy clay, I highly recommend planting your mums in raised beds. This prevents the roots from rotting during wet autumn spells or during the spring thaw.
The Pro-Gardener’s Tip: The Art of Pinching
Have you ever wondered how professional growers get their mums to look like perfect, round balls of color? The secret isn’t a special fertilizer; it’s a technique called pinching.
When your mums are about six inches tall in the late spring, you should literally “pinch” off the top inch of each stem. This encourages the plant to branch out rather than just growing straight up.
You should repeat this process every few weeks until around the Fourth of July. After that, stop pinching so the plant has time to develop its flower buds for the fall show.
It can feel scary to pull bits off your healthy plant, but trust me—it makes a massive difference. A pinched mum will have twice as many flowers as one left to its own devices.
Watering and Feeding for Maximum Blooms
Mums are thirsty plants, especially when they are actively blooming. Because they are often planted tightly together, their leaves can act like an umbrella, shedding water away from the roots.
Always check the soil moisture by sticking your finger an inch into the ground. If it feels dry, water at the base of the plant. Avoid overhead watering, as wet foliage can lead to fungal diseases.
When it comes to feeding, use a balanced, water-soluble fertilizer every two weeks during the growing season. Once the flower buds start to show color, you can stop fertilizing.
If you are growing them in pots, they will dry out much faster than those in the ground. During a hot September, you might need to water your container mums every single day.
Protecting Your Mums from Pests and Disease
While chrysanthemums are generally hardy, they do have a few enemies. Aphids and spider mites are the most common pests. You can usually manage these with a sharp blast of water or insecticidal soap.
Powdery mildew is the most frequent disease. It looks like a white, dusty coating on the leaves. This usually happens when there is poor air circulation or if the leaves stay wet overnight.
To prevent this, space your plants at least 18 inches apart. This allows air to flow freely between them. If you notice infected leaves, remove them immediately and dispose of them in the trash, not the compost pile.
If you see stunted growth or yellowing leaves that don’t respond to water or food, you might have a more serious issue like verticillium wilt. In this case, it is best to remove the plant to prevent the spread to others.
Overwintering Your Mums: A Step-by-Step Guide
If you have planted hardy different types of chrysanthemums, you probably want to see them again next year. Success starts with how you handle them after the first frost.
Do not cut the plants back to the ground in the autumn! Leave the dead stems and foliage intact. They act as a natural insulation for the crown of the plant during the winter months.
- After the ground freezes, apply a thick layer of mulch (about 4-6 inches) around the base of the plant. Straw or evergreen branches work best.
- Ensure the soil is moist before the ground freezes solid. Dry roots are more likely to die in a deep freeze.
- In the spring, wait until you see new green growth emerging from the base before you clear away the old stems.
- Once the danger of frost has passed, you can prune away the dead wood and start your pinching routine for the new season.
Frequently Asked Questions About different types of chrysanthemums
Can I plant the mums I bought at the grocery store in my garden?
You can, but don’t expect them to survive the winter. Most grocery store mums are “florist mums” bred for indoor beauty rather than outdoor hardiness. They are best enjoyed as a temporary splash of color.
When is the best time to plant mums for the best chance of survival?
The best time is actually in the spring. This gives the plant an entire growing season to establish a deep, strong root system. While we love buying them in the fall, those plants often struggle to survive winter because they haven’t rooted deeply enough.
Why did my mums turn brown so quickly after I bought them?
This is usually due to underwatering. Mums in nursery pots are often “root-bound,” meaning there is more root than soil. They dry out incredibly fast. If the root ball dries out completely, the flowers will wilt and turn brown almost overnight.
Do I need to deadhead my chrysanthemums?
While it isn’t strictly necessary for the health of the plant, removing faded blooms (deadheading) will keep the plant looking tidy. It can also encourage the plant to put more energy into the remaining buds, potentially extending the bloom time.
Final Thoughts on Growing Mums
Growing different types of chrysanthemums is one of the most rewarding ways to celebrate the changing seasons. Whether you prefer the architectural beauty of the spider mum or the classic charm of the pompom, there is a variety for every garden.
Remember to prioritize sunlight, keep the soil moist but not soggy, and don’t be afraid to use the pinching technique to get those full, lush shapes. With a little bit of care, these autumn icons will provide a spectacular finale to your gardening year.
So, head out to your local nursery, pick out a few varieties that speak to you, and get planting. Your future self—enjoying a hot cider on a colorful autumn porch—will certainly thank you for the effort today. Go forth and grow!
