Choosing the Right Fast Growing Sunflower Varieties for Your Garden
When you are living off-grid or managing a busy homestead, time is your most valuable resource. You need plants that work as hard as you do, providing shade, food, and beauty without a long wait.
Selecting the right fast growing sunflower varieties depends on your specific goals for the season. Are you looking for a massive “Mammoth” type for seed production, or a shorter branching variety for a splash of color?
Most standard sunflowers take 90 to 120 days to reach maturity, which can feel like an eternity in a short growing season. However, certain cultivars have been bred to hit their peak in as little as 50 to 60 days.
For those in northern climates or high altitudes, these quick-maturing plants are essential. They allow you to harvest seeds and clear the ground before the first hard frost hits your mountain camp or rural plot.
The “Sunrich” Series for Instant Color
If your primary goal is a fast floral display, the Sunrich series is a top contender. These are often used by professional florists because they are pollen-less and reach maturity in about 60 days.
They grow to a manageable height of 4 to 5 feet, making them perfect for smaller garden beds or even large containers near your RV. Their stems are strong, which is a huge plus if your site experiences high winds.
Because they do not produce pollen, they won’t leave a yellow mess on your outdoor furniture. However, keep in mind that since they are pollen-less, they won’t provide the same level of support for local bees as other types.
Early Russian for High-Yield Food Security
The Early Russian is a classic choice for homesteaders who want a balance of speed and size. It typically matures in about 65 to 70 days, which is significantly faster than the standard Giant Mammoth.
This variety produces large heads filled with oil-rich seeds that are excellent for human consumption or as high-protein chicken feed. The stalks are sturdy and can reach heights of 6 to 8 feet quite rapidly.
I recommend this variety if you are looking to build a “living fence.” Their height provides immediate visual privacy from neighbors or passing hikers while you work on more permanent structures.
Top Short-Season Cultivars for Quick Results
Speed isn’t just about the days to maturity; it is also about how quickly the plant establishes its root system. A fast-growing sunflower needs to be aggressive from the moment the seed hits the soil.
When you are out in the wild, you might not have the luxury of a long, pampered growing season. You need “set it and forget it” plants that can handle a bit of rugged weather and still finish their cycle fast.
Let’s look at a few more fast growing sunflower varieties that have proven their worth in various outdoor settings, from backyard gardens to remote homesteads.
Music Box: The Rapid Dwarf Choice
Not every sunflower needs to be a giant to be useful. The Music Box variety is a branching dwarf type that matures in roughly 60 days and stays under 3 feet tall.
These are fantastic for “edging” a campsite or a path leading to your tent. Because they branch out, one plant produces multiple blooms, extending the visual impact without waiting for a single massive head to open.
They are also much easier to protect from deer and rabbits. You can easily throw a bit of hardware cloth or garden netting over these smaller plants compared to the 10-foot giants.
Autumn Beauty for Diverse Colors
If you want a mix of reds, oranges, and deep yellows, Autumn Beauty is a reliable fast-mover. It typically takes about 70 days to reach full bloom, offering a multi-headed display on a 5-foot frame.
This variety is particularly attractive to pollinators. If you are trying to improve the health of your vegetable patch, planting these will bring in the bees and butterflies you need for your squash and tomatoes.
The branching nature of this variety also makes it a great “cut and come again” flower. You can harvest blooms for your table, and the plant will continue to push out new buds for several weeks.
Essential Soil and Sunlight Requirements for Rapid Growth
Even the fastest varieties will stall if they don’t have the right fuel. Sunflowers are “heavy feeders,” meaning they pull a massive amount of nutrients from the earth to build those thick stalks.
To get the most out of your fast growing sunflower varieties, you must focus on the foundation. This is especially true if you are planting in undisturbed soil or a new garden plot in the woods.
Start by choosing a location that receives at least 6 to 8 hours of direct sunlight. The name “sunflower” isn’t a suggestion; these plants literally track the sun across the sky to maximize their energy intake.
Amending Your Soil for Speed
Before planting, work some well-rotted manure or high-quality compost into the top 6 inches of soil. If you are in a survival or remote situation, look for dark, rich forest loam to mix into your planting holes.
Sunflowers love nitrogen during their initial growth phase. A boost of organic fertilizer early on will help them reach their maximum height before they transition their energy into flower production.
Ensure the soil is well-draining. While they need plenty of water to grow fast, their roots will rot if they sit in a boggy area after a heavy rainstorm.
Watering Strategies for Off-Grid Success
Consistency is key for speed. If the soil dries out completely, the plant will go into “survival mode” and stop growing. To keep them on the fast track, aim for deep waterings twice a week.
If you are hauling water to a remote site, use mulch around the base of the plants. Straw, dried grass clippings, or even shredded bark will help hold moisture in the ground and suppress weeds.
I like to use a simple drip system or a “wicking” bucket if I can’t be at the site every day. This ensures a slow, steady supply of hydration that encourages deep root development.
Using Fast Growing Sunflowers for Homestead Privacy and Windbreaks
One of the most practical uses for these plants is creating a “living wall.” If you are living in a van or RV on a new piece of land, you might feel a bit exposed to the elements or the road.
By planting fast growing sunflower varieties in a dense row, you can create a functional screen in under two months. This is a much cheaper and more attractive option than a plastic fence.
The stalks also act as a natural windbreak. This can protect more delicate plants in your garden, like peppers or young greens, from being battered by high-altitude gusts.
Creating a Multi-Layered Screen
For the best privacy, don’t just plant one row. I recommend “staggering” two rows of seeds. Place the taller varieties, like Early Russian, in the back and the shorter Autumn Beauty in the front.
This creates a thick, lush wall that blocks more wind and sightlines. The different heights also ensure that if a pest attacks one variety, the others might still thrive and provide cover.
Remember that sunflowers are annuals. They will die back in the winter, so use this time to harvest the stalks. Dried sunflower stalks are surprisingly strong and can be used as garden stakes for next year’s crops.
Wind Protection and Staking
Because they grow so fast, the stalks can sometimes become “top-heavy” before the root system is fully anchored. This is a common problem in open fields or windy campsites.
If you see your giants leaning, use a simple bamboo stake or a sturdy branch to support them. Tie them loosely with twine or strips of old fabric to allow the stalk to thicken naturally without being strangled.
I often plant my sunflowers near a permanent structure, like a shed or a fence line. This provides a natural “backstop” that helps them stand tall during summer thunderstorms.
Pest Management and Safety for Your Sunflower Patch
In the wild, you aren’t the only one who likes sunflowers. Birds, squirrels, and even larger mammals like deer see your fast-growing plants as a delicious snack bar.
Protecting your investment is crucial. There is nothing more frustrating than watching a plant grow 5 feet in a month only to have a deer decapitate it in a single night.
Early protection is the most effective. Use wire cages or recycled plastic bottles (with the bottoms cut off) to shield the tiny seedlings from slugs and rabbits during their first two weeks.
Deterring Birds and Squirrels
Once the flower heads begin to form, birds will start eyeing the seeds. If you are growing them for your own food storage, you’ll need to cover the heads with mesh bags or cheesecloth.
This allows air to circulate so the seeds don’t mold, but keeps the local blue jays and squirrels from stripping the head bare. If you are growing them specifically for wildlife, you can leave them uncovered.
For squirrels, some homesteaders use a bit of cayenne pepper spray on the stalks. It doesn’t hurt the plant, but the spicy kick often discourages climbing critters from reaching the blooms.
Identifying Common Fungal Issues
In humid environments, sunflowers can fall victim to “powdery mildew.” This looks like white flour dusted over the leaves and can slow down the plant’s growth significantly.
To prevent this, avoid watering the leaves directly. Aim your hose or bucket at the base of the plant. If you see signs of mildew, a simple spray of water mixed with a little baking soda can help manage the spread.
Always remove any heavily infected leaves and move them far away from your garden. This prevents the spores from overwintering in your soil and affecting next year’s crop.
Harvesting and Storing Seeds for Survival and Wildlife
The final stage of the journey is the harvest. Knowing exactly when to cut the heads is the difference between a bowl of delicious seeds and a moldy mess.
Wait until the back of the sunflower head turns from green to a deep yellow or even brown. The tiny petals in the center (the florets) should fall away easily, revealing the mature seeds underneath.
If you are in a race against the weather, you can cut the heads with about a foot of stalk attached and hang them in a dry, well-ventilated area like a garage or a covered porch to finish drying.
Processing Seeds for Long-Term Storage
Once the heads are bone-dry, rub two heads together or use your thumb to pop the seeds out into a bucket. This is a great task to do around the campfire in the evening.
For human consumption, you can soak the seeds in brine and roast them. For long-term survival storage, keep them raw and store them in airtight containers in a cool, dark place.
Sunflower seeds are packed with fats and proteins, making them an excellent addition to a prepper pantry. They can also be pressed for oil if you have the right equipment on your homestead.
Feeding Your Livestock
If you keep chickens or goats, sunflowers are a “superfood.” The seeds provide essential oils that lead to shinier feathers and healthier eggs during the winter months.
You don’t even need to process them for the birds. Just throw a dried sunflower head into the coop and let the chickens peck the seeds out themselves. It provides great entertainment and nutrition.
The dried leaves can also be crumbled and added to goat or rabbit feed as a source of roughage. In a self-sufficient setup, every part of the plant should have a purpose.
Frequently Asked Questions About Fast Growing Sunflower Varieties
How many days does it take for the fastest sunflowers to bloom?
The fastest varieties, such as the Sunrich series or certain dwarf cultivars, can begin blooming in as little as 50 to 60 days. Most standard “fast” varieties take about 65 to 75 days to reach full maturity.
Can I grow these varieties in containers on my RV or balcony?
Yes, but you should stick to the dwarf fast growing sunflower varieties like Music Box or Big Smile. These have smaller root systems and won’t become top-heavy and tip over your pots in the wind.
Do fast-growing sunflowers need more fertilizer?
Because they are cramming a lot of growth into a short window, they benefit from a steady supply of nutrients. Adding compost at planting and a balanced liquid fertilizer every two weeks will help them maintain their speed.
Are all fast-growing sunflowers edible?
While most sunflower seeds are technically edible, some are much better than others. Varieties like Early Russian are bred for large, meaty seeds, whereas “ornamental” types may have very small seeds with thick, hard shells.
