Symphyotrichum Subspicatum
Known affectionately as the Douglas Aster, this hardy perennial is a late-summer superstar across the Pacific Northwest and Western North America. It thrives where other flowers might struggle, painting coastal meadows and woodland edges in shades of violet and lavender just as other summer blooms begin to fade. In various folk traditions, asters were believed to be created from stardust fallen to the earth, a fitting image for their radiant, star-shaped blossoms.
The name Symphyotrichum comes from the Greek words "symphsis," meaning "junction," and "thrix," meaning "hair." This refers to a specific botanical trait of the flower's seed bristles, which are joined together at the base!
To successfully grow Symphyotrichum subspicatum (Prairie Aster), here are some steps you can follow:


To fertilize this plant, apply a balanced, all-purpose fertilizer in the early spring just as new growth begins. Make sure to follow the recommended application rates on the fertilizer package. Water deeply after fertilizing to ensure the nutrients are absorbed by the roots. Avoid fertilizing in the late summer or fall as this can encourage new growth that is vulnerable to winter damage.
Symphyotrichum Subspicatum plant is a type of perennial plant that belongs to the Asteraceae family. When selecting soil for this plant, it is important to consider its specific requirements. The soil should be well-draining and nutrient-rich, with a slightly acidic pH level. It should also be able to hold moisture without becoming waterlogged, as excessively wet soil can lead to root rot. A mix of loam and sand is often recommended for this plant, which provides good drainage while still retaining moisture. Additionally, organic matter such as compost or peat moss can be added to the soil to help improve its nutrient content and structure. It is also important to ensure that the soil is free of any pests or diseases that may affect the health of the plant. Overall, providing the right soil conditions is essential for the successful growth and development of the Symphyotrichum Subspicatum plant.
To propagate this plant, you will need to take stem cuttings from a mature plant. Look for healthy stems that are at least 4 inches long and have several leaves attached. Using a sharp, clean pair of scissors or pruning shears, make a clean cut just below a set of leaves. Remove any leaves from the lower half of the cutting, as they may rot when placed in soil. Dip the cut end of the stem in rooting hormone powder to help encourage root growth.
Next, prepare a pot or container with moist soil. You can use a potting mix that is specifically designed for cuttings or make your own using a mix of peat moss and perlite. Make a hole in the soil using a pencil or your finger and gently place the cutting into the hole. Pat the soil around the stem to ensure that it is firmly in place.
Place the pot in a bright location, but out of direct sunlight. You can cover the pot with a plastic bag or wrap to help maintain humidity levels around the cutting. Keep the soil moist, but avoid overwatering as this can cause the cutting to rot. After a few weeks, you should see new growth emerging from the cutting, which is a sign that it has successfully rooted.
Once the cutting has established roots and is growing strongly, you can transplant it into a larger pot or into the garden. Be sure to choose a location with well-draining soil and plenty of sunshine. Water the plant regularly, but avoid getting the leaves wet as this can promote disease. With proper care, your propagated Symphyotrichum Subspicatum plant will continue to thrive and provide beautiful flowers for years to come.
