The Strategic Value of Rapid-Growth Landscapes
For the off-grid explorer or the modern homesteader, plants are more than just decoration; they are functional tools for land management. Rapidly spreading plants help prevent soil erosion on sloped terrains and suppress stubborn weeds that compete for nutrients.
If you live in an RV or a campervan on a semi-permanent site, these perennials offer a sense of “home” and privacy without the need for permanent structures. They create a natural barrier against wind and dust, making your outdoor living area much more comfortable and secluded.
Furthermore, dense vegetation provides critical habitats for local pollinators and beneficial insects. By choosing fast growing perennials that fill large spaces quickly, you are actively participating in the restoration of your local ecosystem while building a resilient property.
Fast Growing Perennials That Fill Large Spaces Quickly: The Top 10 Varieties
Selecting the right species is the most important decision you will make for your garden’s future. You want plants that are hardy enough to survive your local winters but vigorous enough to dominate the space you have allocated for them.
1. Joe Pye Weed (Eutrochium purpureum)
This native powerhouse is a favorite for those who need vertical height and massive width. It can reach heights of seven feet in a single season, producing large, vanilla-scented flower clusters that attract butterflies by the dozen.
Joe Pye Weed thrives in moist soil and full sun, making it perfect for damp areas of your property where other plants might struggle with “wet feet.” It spreads via rhizomes, ensuring a thick, hedge-like appearance within two or three years.
2. Perennial Geranium (Rozanne)
If you need a reliable groundcover that blooms from late spring until the first frost, look no further than the Rozanne Cranesbill. This plant is famous for its ability to mound and spread, covering several square feet per individual plant.
It is incredibly hardy and tolerates a wide range of soil types, from sandy loam to heavy clay. Its dense foliage acts as a living mulch, keeping the soil cool and preventing weed seeds from germinating in your garden beds.
3. Hostas (Large Varieties like ‘Empress Wu’)
For shaded areas under large trees or north-facing walls, hostas are the undisputed kings of coverage. Varieties like ‘Empress Wu’ can grow up to four feet tall and six feet wide, with massive leaves that command attention.
Hostas are easy to propagate; you can divide the root ball every few years to create even more plants for free. This makes them an excellent choice for budget-conscious homesteaders looking to fill massive woodland areas over time.
4. Creeping Phlox (Phlox subulata)
This is the ideal solution for rocky hillsides or edges where you want a “carpet” effect. Creeping phlox stays low to the ground but spreads outward rapidly, creating a dense mat of evergreen foliage and vibrant spring flowers.
It is highly effective at erosion control, as its root system helps bind the soil together. Use a hori-hori knife to plant small plugs every twelve inches, and they will likely touch by the end of the first year.
5. Bee Balm (Monarda)
Bee Balm is a member of the mint family, which should tell you everything you need to know about its growth rate. It spreads quickly through underground runners and produces unique, shaggy flowers that hummingbirds find irresistible.
Beyond its beauty, Bee Balm has medicinal and culinary uses, fitting perfectly into a self-sufficient lifestyle. Be sure to provide plenty of airflow between plants to prevent powdery mildew, a common issue with dense, fast growers.
Essential Tools for Planting Large Areas
Filling large spaces requires more than just a standard hand trowel. To work efficiently and protect your body from strain, you need the right gear designed for heavy-duty landscaping and homesteading tasks.
- Long-Handled Digging Shovel: Choose one with a sharpened steel blade to cut through tough roots and sod easily.
- Garden Fork: This tool is essential for aerating compacted soil and mixing in organic compost without destroying the soil structure.
- Wheelbarrow or Garden Cart: Moving multiple large perennial pots and bags of mulch is back-breaking work without a reliable set of wheels.
- Bypass Pruners: High-quality pruners, like those from Felco, are necessary for trimming back aggressive growth and deadheading flowers.
- Soaker Hoses: When establishing fast growing perennials that fill large spaces quickly, consistent moisture is vital during the first season.
Investing in durable, professional-grade tools will save you time and money in the long run. Cheap tools often break when faced with the heavy clay or rocky soil common in wilder, off-grid locations.
Step-by-Step Guide to Rapid Landscape Transformation
Preparation is the difference between a thriving garden and a patch of dead sticks. Follow these steps to ensure your new perennials have the best possible start in their new home.
Step 1: Analyze Your Site
Observe the area for a full day to determine how many hours of direct sunlight it receives. Check the drainage by digging a small hole and filling it with water; if it takes hours to drain, you have heavy clay.
Step 2: Prepare the Soil
Clear away existing weeds and grass. Instead of tilling, which can wake up dormant weed seeds, consider the “sheet mulching” method. Lay down cardboard and cover it with six inches of wood chips or compost.
Step 3: Space for the Future
It is tempting to plant perennials close together for an instant look. However, fast growing perennials that fill large spaces quickly need room to breathe. Always follow the spacing recommendations on the plant tag, usually 18 to 36 inches apart.
Step 4: Deep Watering
After planting, water each perennial deeply to settle the soil around the roots. For the first two weeks, check the soil daily. If the top inch is dry, it is time to water again to prevent transplant shock.
Safety and Management: Avoiding Invasive Nightmares
There is a fine line between a “vigorous grower” and an “invasive species.” Some plants grow so fast they can escape your garden and damage the local wilderness, which goes against the principles of sustainable outdoor living.
Always research whether a plant is considered invasive in your specific region before putting it in the ground. For example, Mint and Bamboo are legendary for their growth, but they can easily take over an entire acre if not contained with physical barriers.
If you notice a plant spreading into areas where it isn’t wanted, use your bypass pruners to remove the flowers before they set seed. For plants that spread by runners, you may need to install a deep plastic root barrier to keep them in check.
When in doubt, consult with local park rangers or a university extension office. They can provide lists of native fast growing perennials that fill large spaces quickly that support local wildlife without threatening the environment.
Maintenance Tips for High-Growth Perennials
Fast growth means fast metabolism. These plants require regular “fuel” and occasional grooming to stay healthy and looking their best throughout the year.
Apply a thick layer of organic mulch every spring. This suppresses weeds, retains moisture, and slowly adds nutrients back into the soil as it decomposes. Leaf mold or composted wood chips are excellent choices for a natural look.
Many fast-growing plants benefit from “division” every three to four years. This involves digging up the entire clump in early spring and cutting it into smaller sections with a sharp spade. Replant the sections to expand your garden for free.
Cut back dead foliage in late winter or early spring. This allows the new shoots to emerge without being smothered by last year’s growth. Leaving the stalks up during winter provides a vital winter refuge for beneficial insects and birds.
Frequently Asked Questions About Fast Growing Perennials
What is the fastest growing perennial for full sun?
The Blanket Flower (Gaillardia) and Walker’s Low Catmint are exceptionally fast growers in sunny spots. They can double in size in a single season and provide massive color and coverage with very little water once established.
Can I plant these perennials in the fall?
Yes, fall is an excellent time to plant. The cooler air temperatures reduce stress on the foliage, while the soil is still warm enough for the roots to grow. Just ensure you plant at least six weeks before the ground freezes.
How do I stop fast perennials from becoming “leggy”?
To keep plants bushy rather than tall and thin, practice “pinching.” Early in the season, snip off the top inch of new growth. This encourages the plant to send out side branches, resulting in a much denser fill for your space.
Are there fast-growing perennials that are deer resistant?
Yes, many aromatic perennials like Lavender, Russian Sage, and Bee Balm are ignored by deer. Their strong scents and textured leaves make them unappealing to browsing wildlife, allowing them to grow undisturbed.
Summary of Key Takeaways
Transforming a large, empty lot into a lush sanctuary doesn’t have to take a decade. By focusing on fast growing perennials that fill large spaces quickly, you can achieve professional results on a homesteader’s timeline.
Remember to prioritize soil preparation and choose plants that match your specific light and moisture conditions. Use the right tools to protect your back and your time, and always be mindful of the difference between vigorous growth and invasive behavior.
Whether you are settling into a new off-grid property or just want to add some privacy to your RV site, these plants are your best allies. Start small, plant smart, and watch as nature does the heavy lifting for you.
Stay safe, keep your hands in the dirt, and enjoy the incredible transformation of your outdoor space!
