Guide to Planting Maximilian Sunflower: Tips & Benefits

Giant, golden Maximilian sunflowers (Helianthus maximiliani) are a dazzling addition to any garden. These towering plants, reaching heights of up to 10 feet, brighten your garden from late summer through fall. If you're considering planting Maximilian sunflowers, this guide will get you started. We'll cover everything from choosing the perfect location to watering tips for optimal growth and abundant blooms. 

Maximilian Sunflower Planting Guide

Choosing the Right Location

Maximilian sunflowers crave full sun. Look for a spot that receives at least 6-8 hours of direct sunlight daily. This sun-drenched environment helps them grow and in no time you'll be seeing a fully bloomed Maximilian sunflower.  

Soil Preparation 

To give your Maximilian Sunflowers the best start, pay attention to the soil they will be planted in. These sunflowers thrive in well-drained, loamy soil that is rich in organic matter. To prepare the soil, start by loosening it and remove any weeds or debris. 

Additionally, you can enhance the soil's fertility by adding compost or well-rotted manure. If you're unsure of your soil drainage, observe it after heavy rain. Standing water is a sign you may need to amend your soil.

Planting and Spacing Guidelines

Plant Maximilian sunflower seeds directly outdoors in the spring, after the last frost. Alternatively, you can start them indoors 4-6 weeks before the last frost date for your specific area. Sow the seeds at a depth of approximately 1/2 inch.

If you prefer, you can buy Maximilian sunflower plants from a reputable nursery like TN Nursery. When planting the nursery-grown plants, make sure to plant them at the same depth as they were growing in the nursery container.

Regardless of whether you choose to start from seed or seedling, you need to place the plants evenly. Leave a gap of 18-24 inches between each sunflower plant. This spacing gives them sufficient room to develop roots and prevents overcrowding.

Watering and Fertilization Tips

During their first year, Maximilian sunflowers need regular watering to develop strong roots. Water once or twice a week, providing about an inch of water in total, depending on weather conditions. Adjust watering as needed to keep the soil consistently moist but not soggy.

Overfertilization can lead to excessive foliage and fewer blooms. A light application of balanced, slow-release fertilizer at planting time is usually sufficient. If your soil is particularly poor, you can supplement it with a diluted liquid fertilizer once or twice during the growing season.

Maintenance Tips for Growing Maximilian Sunflower

Follow these tips to grow a beautiful Maximilian sunflowers in your garden:

Mulching

Apply a layer of organic mulch around the base of the plants. This will help retain moisture in the soil, regulate soil temperature, and suppress weed growth, giving your sunflowers the best chance to thrive.

Support the Stem

Maximilian Sunflowers can grow tall and become top-heavy. Prevent bending or breaking during strong winds or heavy rainfall by providing stakes or a trellis system for support. This will keep your sunflowers upright and flourishing.

Deadheading

Regularly remove spent flowers by deadheading. This practice encourages continuous blooming, redirecting the plant's energy towards producing new blooms rather than seed production. It also maintains a tidy and beautiful appearance in your garden.

Brighten Your Garden By Planting Maximilian Sunflowers

With this guide, you're ready to start your sunflower garden. Remember planting Maximilian sunflowers requires patience and care. Don't forget to choose the right location, provide ample sunlight, and water your Maximilian sunflowers properly. Lastly, consider using mulch to retain moisture and suppress weeds, support their tall stalks if needed, and deadhead spent blooms to prolong flowering.

The famed German explorer first came upon these magnificent flowers during his North American expeditions, and they were dubbed Helianthus in his honor. It is a suitable title, especially since any outdoor environment is lucky to be bestowed with these golden gems. They are a native perennial coveted for their height, versatility, and blazing yellow hues. It's easy to grow even if you have little gardening experience. The following post concerns this gorgeous bloomer and how it can add life to your outdoor spaces. What Does It Look Like?  People often hear "sunflower" and think of a bloom with a black central disc surrounded by blazing yellow petals. And while they share some characteristics with common sunflowers, there are some distinctions. For instance, their central disc is smaller than a typical sunflower and does not contain blackened florets.  Instead, the hub of the Maximilian Sunflower is populated by clusters of tiny, yellow florets that provide sustenance for pollinators. So, their entire bloom is varying shades of yellow. One thing they share with its more common sunflower relative is height. They can grow to a height of 10 feet!  The flower is supported by a long, narrow stem covered in coarse hairs. Alternate, blade-shaped leaves adorn the towering stem, growing as high as just under the flower bloom. The proximity of the green leaves to the actual flower provides a stunning juxtaposition of natural color evocative of the sun setting over verdant hills. Their conehead is filled with intricate patterns of bronze to bright yellow florets. The mesmerizing structure of these tiny florets belies the mostly uniform layers of petals that envelope them. The florets produce seeds that are a food source for various bird species.  It is also unique among its genus because one stem can support a cluster of flowers instead of just one. Naturally, they grow dense and can colonize very quickly if allowed to. This makes them a good option for filling a large area with golden hues. However, if you have limited space to work with, the multi-flower growths of the slender stems still allow for a radiant burst of color in tight spaces.  Blooms of them are typically 5 inches in diameter, with a central disc spreading out to about one inch in diameter.  What Are the Benefits of Them?  They can add a gilded, regal quality to your outdoor spaces, but that's not all they bring. Take a look at the following reasons why people love to grow these plants:  They Support the Local Nectar Bee Population - Bees flock to them because they produce nectar. Moreover, it produces nectar at a time of year when other perennials become barren. So, they are an excellent choice to keep bees returning to your garden late into the season. As if the inherent chroma of the flower weren't enough, it also attracts colorful, nectar butterflies.  Late Blooming- Many add them to their gardens because they bloom into late fall. This unique blooming span makes this flower ideal for maintaining color throughout the year.  Very Tolerant—While it prefers dry to moist soils, it can tolerate many conditions. It's not uncommon for this plant to thrive in loamy or limestone-rich soil. Great for Bird Lovers- The fertile florets of the flower produce seeds late into the season, which attract a wide variety of birds. The flower is a no-brainer if you are an avid bird-watcher or enjoy providing a haven for avian wildlife.  If you need to become more familiar with this perennial, you may have questions about how to grow and maintain them. So, let's address some common questions about this rewarding flower.  Do They Come Back Every Year?  Another way it distinguishes itself from other sunflowers is that it's a perennial—many sunflowers are annuals. It is supported by a hardy rhizome that will produce new growth yearly.  How Tall Do Maximilian Sunflowers Get? They are known for their stature, reaching up to 10 feet. Its blooms stretch more or less upright toward the sky, giving them a stately appeal that contrasts nicely with flowers and plants that grow closer to the ground.  How Do You Plant them?  It needs between 6 and 8 hours of sun per day. Sow the seeds directly into the soil at about half an inch depth. Seeds should be planted in spring. Be sure to leave between 18 and 24 inches between each plant to allow the root system to grow correctly and avoid crowding. Do You Need to Deadhead Them?  Deadheading will keep blooms coming back and keep the plant looking clean. It would help if you deadheaded dying flowers as they appear. Deadheading will also stymie seed production to avoid spreading to other parts of your garden.  Should You Support the Stem of the Maximilian Sunflower They can grow to be very tall. Their stems are naturally skinny, so you may need to support them with stakes. If you see the plant start to bend or sag, or if you live in an area that experiences high winds, helping the stems with stakes may be necessary. Overly rich soil may also promote hardy blooms with weak stems. If you notice that yours are arching before they bloom, you may need to amend the soil to make it less fertile.  TN Nursery is your source for many native species, from lush ferns to pollinating perennials.
