“Plants Profile for Symphyotrichum Lateriflorum (calico Aster).” Plants Database. “A Comparative Study of Cultivated Asters.” Plant Evaluation Notes 36 (2013): 1-11. “Calico Aster Is a Shade-Loving Pollinator Nirvana.” Houzz. “Calico Aster (Symphyotrichum Lateriflorum).” Calico Aster (Symphyotrichum Lateriflorum). Figure 6: Photo showing stems and blooms of S. Stems: Immature steams are green non-wooded and as they mature they turn red with small white hairs. Hair: None on outside, inside hairs along veins lateriflorum * Bracts *Ĭolor: Some pinkish red others are green, however tips are different colors 5” across, narrowing at stemĬolor: Top of the leaf has a medium green color while the under is lighterįigure 5: Photo of leaves and blooms of S. Shape: Lancolated with pointed ends and base, teeth at tip Size: 1.3 – 2.2 mm Figure 4: Sketch of achene from S. Hairs: Red, purple, brown or white that are hooked and roughly 3-4 mm in length arenaria most effective pollinator (on left) and Platycheirus the least effective pollinator (on the right)įruit: Achenes, dry fruit, covered in short hairs
The least effective pollinators for the flower were found to all be from the hoverfly family and included Platycheirus, Bufolucilia, and Eristalis which scored 11.3, 16.0, and 18.5 respectively.įigure 3: D. lateriflorum were found to be Vespula maculifronsor the eastern yellow jacket that scored 215.4 PPE, and Lasioglossum commonly known as sweet bees which scored 180.6 PPE. This is interesting considering that the honey bee only scored a 89.7 PPE. arenaria is more commonly known as the aerial yellow jacket and was found to be the top pollinator of the flower with a potential pollinator effectiveness rate or PPE of 220.8. lateriflorum is not the honey bee which one might expect but instead is Dolichovespula arenaria.
lateriflorum *Īccording to a study done by Horsburgh, Semple, and Kevan in 2011, the most effective pollinator for S. lateriflorum bloom * Pollinator effectiveness in S. Shape: Linear-oblong shaped about 3-8 mm longįeatures in flowerhead: Each ray flower has one narrow and long ligule, which looks and acts as the flower’s petals Figure 2: Bee on S. Reproduction: Some flowers are perfect some are imperfect, also rhizomatous clonal reproductionįlower Head: Shaped like a cone, roughly 1/3 of an inch across, made up of disk and ray flowers * Disk Flower *Ĭolor: Pale yellow coloration when immature, reddish purple to brown at maturityįeatures in flowerhead: These flowers function as what is traditonally veiwed as the center of the flower * Ray Flower * Timing of Blooms: Late summer to early fall (1-2 months long) Growth pattern: Panicles of flower heads which can be 10 inches by 6 inchesįlower classifications: Composite, each flower head has many smaller disk florets (6-10) which are surrounded by 8-16 ray florets Native: Eastern United States and British Colombia CanadaĬonditions: Full sun and moist soil Figure 1: S. Habitat: Woodland, moist meadows, prairies Other names: Side-Flowering Aster, Small White Aster, Fall Aster, and Goblet Aster This plant is also very hardy and robust as it is both mildew and rust resistant which was found in Dr. In fact, over a hundred insect species in the early fall are dependent on this plant for survival. lateriflorum helps them do as it provided nectar. A fall bloom is important because during the fall is when the bugs, and pollinators are perhaps most active as they are preparing for winter, which S. This plant is very important to the ecosystem as it is a fall blooming plant. lateriflorum is very special and has wonderful coloration, in fact it was named for the diverse coloration of the disk florets at maturity. It belongs to the Asteraceas family which is the plant family with the most evolutionized specialization and makes up 21,000 different species. Calico aster or Symphyotrichum lateriflorum is one of the 250 types of asters which can natively found in North America today.
