Asters are a great way to add vibrant, late-season color to your garden
Asters are a group of flowering perennials belonging to the Asteraceae family (they're not mums), known for their daisy-like blooms that appear in late summer and fall.
Their flowers come in a variety of colors, including shades of purple, pink, blue, and white, with yellow centers. Asters are native to temperate regions of North America and Europe and are often seen in gardens and wildflower meadows.
These plants are valued for their ability to provide late-season color, often blooming when many other plants have finished for the year. Asters range in height from low-growing ground covers to taller varieties that can reach up to four feet.
They are easy to grow and attract pollinators like bees and butterflies, making them a favorite for both ornamental and wildlife gardens.
Asters thrive in full sun with well-draining soil and are known for their hardiness - they easily withstand cool temperatures and light frosts.

How to Grow Asters
- Location & Light: Asters prefer full sun to partial shade, with at least six hours of direct sunlight daily. Choose a well-drained location to prevent root rot, as Colorado's soil can often be heavy with clay.
- Soil Preparation: Amend your soil with organic matter like compost to improve drainage and nutrient content. Asters prefer slightly acidic to neutral pH, so test the soil if possible and adjust accordingly with organic fertilizers or soil amendments.
- Planting Time: In Colorado, it's best to plant asters in spring or early summer, after the danger of frost has passed. This allows them to establish a strong root system before the winter.
- Watering: Asters need consistent watering, especially in Colorado’s dry climate. Water deeply but allow the soil to dry slightly between watering to avoid overly wet conditions, which can cause root rot.
- Mulching & Maintenance: Use mulch to help retain moisture and protect the roots from temperature fluctuations. Deadhead spent blooms to encourage continued flowering and cut back plants in late fall to promote healthier growth in the following season.
