Calico Aster Symphyotrichum lateriflorum var. horizontale
ABOUT
The plant known as calico aster is distinguished by its striking floral display and growth habit. This variety of aster is characterized by its branching stems which bear a profusion of small flowers. The blossoms are daisy-like, with a typical structure having a yellow center composed of disc florets, which may mature to a reddish-purple. Surrounding these are the star-shaped rays, which are commonly white to pale lavender in color. The leaves of the calico aster are narrow and lance-shaped, sometimes with a slightly toothed edge, becoming smaller as they ascend the stems. The calico aster is a versatile plant that can create a vivid splash of color in autumn when many other plants are fading. It has a bushy appearance with a generous leaf to flower ratio, providing not just aesthetic appeal but also a habitat for various forms of wildlife. The delicate texture of the leaves and the frothy appearance of the numerous small flowers contribute to a softening effect in the garden landscape, offering a gentle contrast to the more substantial foliage of neighboring plants. This plant can give a garden a wildflower-like charm and is often admired for its late-season ornamental contribution.

WaterWater the Calico Aster deeply and consistently, aiming to keep the soil evenly moist but not waterlogged. They typically need about 1 inch of water per week, through a combination of rainfall and supplemental watering. In the absence of rain, water the plant with about 0.5 gallons spread out over the week, preferably in the morning to allow foliage to dry out. Increase the frequency during periods of drought or extreme heat, but allow the top inch of soil to dry out between waterings to prevent root rot. During the winter, reduce the amount as the plant requires less water while dormant.
LightCalico Aster flourishes best in full sun to partial shade. The ideal location would offer morning sunlight and some light afternoon shade to protect from the intense heat, especially in hotter climates. Ensure it receives at least 6 hours of direct sun daily for optimal flower production.
TemperatureCalico Aster is cold-hardy and can typically withstand temperatures down to about -30 degrees Fahrenheit. Optimal growing conditions are found between 60 to 75 degrees Fahrenheit. They can survive in higher temperatures as well, but prolonged exposure to temperatures over 85 degrees Fahrenheit might stress the plant.
PruningPrune Calico Aster to maintain its shape and encourage bushier growth. Deadhead spent flowers regularly to promote continued blooming. In late fall or early spring, cut the plant back to a few inches above the ground, as it is a perennial and will grow back. Pruning is typically done annually.
CleaningAs needed
SoilCalico aster prefers well-draining soil that's rich in organic matter with a pH ranging from 5.8 to 6.5. For the best soil mix, combine garden soil, compost, peat moss, and perlite to ensure good drainage while retaining adequate moisture.
RepottingCalico asters do not typically need frequent repotting as they are perennial plants. Repotting every 2-3 years or when the plant outgrows its container can be beneficial to refresh the soil and provide room for growth.
Humidity & MistingCalico asters thrive outdoors and do not require specific humidity levels; they are adaptable to the ambient humidity present in their native environment or typical garden settings.
Suitable locationsIndoor
Ensure bright indirect light, consistent watering, and good air flow.
Outdoor
Plant in partial sun, well-draining soil, and water regularly.

Life cycleSymphyotrichum lateriflorum var. horizontale, commonly known as Calico Aster, begins its life cycle as a seed which germinates in spring when soil temperatures increase. The seed establishes a root system and produces a small rosette of leaves. Throughout the growing season, Calico Aster forms an upright stem with alternately arranged leaves, and by late summer to fall, it develops numerous flower heads characterized by a center of disc florets surrounded by white to pale purple ray florets. After flowering, pollination primarily by insects enables seed formation. The plant then disperses its seeds in late fall to mid-winter, completing its annual reproductive cycle. Finally, the Calico Aster enters dormancy during the winter months, with its roots or basal rosette surviving until the next growing season.
PropogationPropogation time
Early spring
Propogation: The most popular method of propagating the Calico Aster (Symphyotrichum lateriflorum var. horizontale) is by division. The best time to divide Calico Aster plants is in early spring, just as new growth begins to emerge. To propagate by division, first carefully dig up an established plant, making sure to keep a good amount of soil around the roots. Gently separate the plant into smaller sections, each with a portion of the root system and several shoots. Replant the divisions immediately, spacing them about 18 inches (approximately 45.72 cm) apart to give them room to grow. Water the new divisions thoroughly after planting to settle the soil and reduce transplant shock. This method allows for quick establishment of new plants and will typically result in blooms the following fall.
