Ornamental grasses with purple flowers can add a pop of color and texture to your garden. These plants are relatively low maintenance and can thrive in a variety of conditions.

One of the most popular ornamental grasses with purple flowers is the Fountain Grass, which produces delicate purple plumes in the summer months. Some species of Fountain Grass can grow up to 3 feet tall, making them a great option for adding height to your garden.

To grow ornamental grasses with purple flowers, you'll want to choose a spot that gets full sun and has well-draining soil. This will help prevent the roots from rotting and ensure the plant stays healthy.

Purple Fountain Grass is also a great choice for attracting butterflies and hummingbirds to your garden, as it produces nectar-rich flowers that are a favorite of these pollinators.

Water them regularly, but make sure not to overwater, as this can lead to root rot. In fact, it's best to water them in the morning, so the plants have the entire day to dry out slightly.

Fertilize your ornamental grasses in the spring with a balanced fertilizer, following the instructions on the package to avoid overfertilizing. I've found that this helps promote healthy growth and vibrant purple flowers.

Common Problems

Common Problems with Purple Fountain Grass can arise if growing conditions aren't right.

Propagation and Bloom

You can easily multiply your purple fountain grass by division or seeds, but division is a faster and more reliable method. The plants may self-seed in the garden, but division is the way to go for a quicker result.

To propagate by division, dig up the plant in the fall after it's finished flowering and going into dormancy. Cut it into sections with healthy roots and leaves using a clean, sharp tool.

Discard any rotten or dead plant matter and roots, and replant the sections immediately. Keep the soil moist as the new divisions settle into their new home.

Propagating

Propagating purple fountain grass is a relatively easy process that can be done through division or seeds.

You can propagate purple fountain grass through division in the fall, after the plant has finished flowering and is going into dormancy. This method is faster and more reliable than waiting for seeds to germinate.

To divide the plant, dig it up and use a clean, sharp cutting tool to cut it into sections that contain healthy roots and leaves. Discard any rotten or dead plant matter and roots.

You can also propagate purple fountain grass from seeds, which can be collected from the flowering stems in the fall.

Here's a step-by-step guide to growing purple fountain grass from seeds:

  1. Take the whole stem and allow the flower stalk to dry out in a cool place. Collect the dry seeds from the flower plume.
  2. Surface sow the seeds in good potting soil with just a dusting of sand on top.
  3. Water until the container is evenly moist.
  4. Place the pot in a plastic bag or cover it with a plastic dome. Cut a couple of small slits on top of the bag so seeds can breathe.
  5. Once you have seedlings with two sets of true leaves, transplant them to larger pots.
  6. Harden off the plants in the spring and install them in prepared containers or beds.

Bloom Months

Bloom Months are a crucial consideration for gardeners. Purple fountain grass blooms from late spring to early fall.

Some plants bloom throughout the year, but others have specific seasons. For example, purple fountain grass is a great choice for warm weather.

If you're planning a garden, it's essential to choose plants that bloom during the same months. This ensures a continuous display of color and beauty.

In warmer climates, some plants like purple fountain grass can bloom for several months.
