What Are Perennials?

Perennials are plants that live for more than two years, unlike annuals that complete their life cycle within one year. Perennials typically die back to the ground in the winter and then reemerge in the spring from the same root system.

They can produce flowers and foliage year after year, making them a popular choice for gardeners who want to create a lasting and sustainable garden.

Perennials come in a wide variety of shapes, sizes, and colors, and they can be used in many different types of gardens, including borders, rock gardens, and container gardens. Some examples of popular perennial flowers include peonies, hostas, and daylilies.

How To Plant Perennials?

Planting perennials is a relatively simple process that can be broken down into a few basic steps:

  1. Select the right location: Perennials require different amounts of sunlight, water, and soil types, so choose a spot in your garden that meets the needs of the specific plant you are planting. Most perennials require well-draining soil, and some may need partial shade.
  2. Get the soil ready: Loosen the soil in the planting area with a shovel or garden fork and remove any weeds or debris. If the soil is clay-like or heavy, mix in some compost or other organic matter to increase drainage.
  3. Dig the planting hole: Create a hole that is a bit wider and deeper than the root of your plant. Be careful not to plant too deeply – the top of the root ball should be level with the soil surface.
  4. Plant the perennial: Put the plant inside the hole and fill with soil, pressing to eliminate any pockets of air. Make sure to water thoroughly.
  5. Mulch: Apply a layer of mulch to the bottom of the plant to keep it moist and prevent weeds.
  6. Care: Water your plant regularly, especially during the first few weeks while it is getting established.

Once established, many perennials require less water than annuals. Deadhead spent flowers to promote continued blooming, and fertilize as needed according to the specific requirements of the plant.

By following these basic steps, you can successfully plant perennials and enjoy their beauty and benefits year after year.

Caring For Perennials

Here are some tips for caring for perennials:

  • Watering: Perennials require regular watering, especially during hot and dry periods. Water deeply once a week, rather than lightly more frequently, to encourage deep root growth. Avoid overhead watering, which can promote fungal diseases. Water the plant at the bottom instead.
  • Mulching: Adding some organic mulch, like bark or shredded leaves, can help keep in moisture, regulate soil temperature, and prevent weeds. Apply a 2-3 inch layer around the bottom of the plant, taking care not to bury the stem.
  • Deadheading: Removing spent flowers regularly can encourage continued blooming and prevent the plant from putting energy into seed production. Cut off the flower stem just above a healthy leaf.
  • Fertilizing: Perennials generally do not require heavy fertilization, but a light application of a balanced fertilizer in early spring can help promote growth and flowering. Follow the recommended dosage on the fertilizer label.
  • Pruning: Many perennials benefit from a light pruning in early spring to remove dead or damaged foliage and promote new growth. Cut back the plant to just above a healthy set of leaves.
  • Division: Over time, some perennials may become overcrowded and require division to maintain their vigor and flowering.

Dividing a plant involves digging up the entire clump, dividing it into smaller sections, and replanting them. This is typically done in early spring or fall, depending on the plant.

If you follow these tips and pay attention to the specific requirements of your perennials, you can help ensure that they thrive and provide you with years of enjoyment.

Why Choose Blue Perennials?

Blue perennials are a popular choice among gardeners for several reasons:

  • Calming and Soothing: The color blue is often associated with calmness and serenity, making blue perennials an ideal choice for creating a peaceful and relaxing garden environment.
  • Versatility: Blue perennials come in a wide range of shades, from pale sky blue to deep navy, and can be used in a variety of garden styles, from formal to cottage gardens.
  • Eye-catching: The color blue stands out in the garden and can be used to create a focal point or draw the eye to specific areas of the garden.
  • Complementary: Blue perennials can complement other colors in the garden, such as pink, yellow, and white, and can help create a cohesive and harmonious color scheme.
  • Pollinators: Many blue perennials, such as salvia and agapanthus, are attractive to pollinators like bees and butterflies, which can help promote a healthy garden ecosystem.
