How Much Space to Leave Between Each Live Forever Plant

Updated: July 12, 2023

When it comes to planting live forever plants, also known as perennial plants, one important factor to consider is the amount of space to leave between each plant. Proper spacing not only ensures the healthy growth and development of the plants but also allows for efficient maintenance and overall aesthetics of the garden. In this article, we will explore the ideal spacing requirements for live forever plants, taking into account their growth habits and specific needs.

Understanding Live Forever Plants

Live forever plants are a diverse group of perennial plants that have the ability to survive for multiple growing seasons. They come in various shapes, sizes, and growth habits, ranging from groundcovers to tall shrubs. Some popular live forever plants include lavender, coneflowers, salvia, and sedum.

These plants have different growth rates and spread patterns. While some live forevers tend to clump and grow upright in a compact manner, others tend to spread vigorously through runners or rhizomes. Understanding the specific growth habits of your chosen live forever plants is crucial in determining the appropriate spacing.

Factors to Consider

  1. Plant Size: The mature size of the live forever plant is an important factor to consider when determining spacing. Larger plants generally require more space to ensure they have enough room for proper root development and to prevent overcrowding.

  2. Growth Habit: As mentioned earlier, live forever plants can have different growth habits such as clumping or spreading. Clumping varieties usually require less space between each plant, while spreading varieties need more room to prevent overcrowding.

  3. Soil Fertility: Soil fertility plays a role in determining how much space to leave between live forever plants. Nutrient-rich soils can promote vigorous growth, which may require more space for the plants to spread out. On the other hand, poor soil conditions may result in slower growth, allowing for closer spacing.

  4. Climate and Environmental Factors: The climate and environmental conditions of your region can also influence the spacing requirements for live forever plants. In areas with hot and dry climates, more space may be needed to provide better air circulation and reduce competition for water and nutrients. In cooler regions, closer spacing may be appropriate to create a warmer microclimate for the plants.

Spacing Guidelines

While each live forever plant has its own specific spacing requirements, here are some general guidelines to follow:

  1. Small Clumping Plants: For small clumping live forevers, such as sedums or hens and chicks (Sempervivum), a spacing of 6 to 12 inches (15 to 30 cm) between each plant is typically sufficient. This allows them to fill in the space without becoming overcrowded.

  2. Medium-sized Clumping Plants: Medium-sized clumping live forever plants, such as lavender or coneflowers, generally require a bit more space between each plant. A spacing of 12 to 18 inches (30 to 45 cm) will allow them to grow and spread without crowding each other.

  3. Large Clumping Plants: Larger clumping varieties, like ornamental grasses or tall phlox, need even more space to reach their full potential. Aim for a spacing of 18 to 24 inches (45 to 60 cm) or more between each plant to ensure proper growth and prevent overcrowding.

  4. Spreading Plants: Live forever plants with spreading growth habits, such as creeping thyme or groundcover roses, require wider spacing compared to clumping varieties. Depending on their growth rate and vigor, a spacing of 18 to 36 inches (45 to 90 cm) or more may be necessary.

  5. Vertical Spacing: In addition to horizontal spacing between each plant, it is also important to consider vertical spacing. Taller live forever plants should be placed towards the back of the border or garden bed to prevent shading and overcrowding of shorter plants.

Conclusion

Proper spacing between live forever plants is essential for their healthy growth, optimal development, and overall garden aesthetics. By considering factors such as plant size, growth habit, soil fertility, climate, and environmental conditions, you can determine the ideal spacing requirements for your chosen live forever plants. Following the general guidelines provided in this article will help you create a well-planned and visually appealing garden that thrives with perennial beauty year after year.
