Perennial Planted LiveWalls are easy in mild climates (like San Diego, Seattle or Tampa), with very few losses, even during winter. If well maintained, certain plant species can last for years.
In cold winter climates (like Michigan, Maine or Minnesota), living walls planted with perennials require diligent oversight and adherence to timely maintenance events to optimize overwintering. If all care is done correctly and on time, we have found that:
- Winter survival can be good (90+ %) during mild winters,
- Winter survival can be fair (70+ %) during average winters, and
- Winter survival can be poor (25% or less) following harsh winter weather.
