Collection: Soil Conditioners

Perennial plants live for more than two growing seasons. If properly cared for, they will return year after year with consistent bloom times to add color and diversity to your garden.

The key difference between annuals and perennials is their lifespan. Annuals live for one growing season, although some of our annual plants do re-seed, thereby prolonging their benefits past a single season. Perennial plants and perennial flowers persist for several years, returning year after year, every growing season. Another difference is that true annuals will bloom throughout the entire season; whereas, perennials may bloom intermittently during or between seasons.

Perennial plants and flowers provide lasting beauty and structure to your garden. They have specific seasonal bloom times that remain consistent year after year, ensuring vibrant color for your garden throughout the seasons. Perennials also contribute to biodiversity and help the overall environment. Their deep root systems help prevent soil erosion and retain nutrients, while also sequestering carbon. Planting lots of different perennials with varied bloom times ensures consistent, reliable food sources for bees, butterflies, hummingbirds, and beneficial wildlife.

The ideal time to plant perennials is spring or early fall. This allows them to establish their root system before extreme weather.

In general, Perennials need watering, occasional fertilization, and deadheading to encourage repeat blooming. The specific care needs can vary by type. At Annie’s Annuals & Perennials, we offer many native and low water, low-maintenance perennials to make planting and caring for them easy. We want to make gardening success attainable for everyone.
