Zinnias have been cultivated by gardeners since the 19th century. Due to Zinnias are so bright in color they attract many species of inspects and animals that help in the pollination process. Though there is little description in plant journals Zinnias look to have both a pollen center and miniature flowers that contain nectar. This could be a contributing factor to the wide range of pollinators attracted to this flower. Zinnias are most attractive and are often found with butterflies due to their bright color and strong perfume-like odor. For this reason they are a common plant species in butterfly gardens. Another advantage of having Zinnias in your garden is they have two blooming seasons, one in the fall and one in summer. These flowers should thrive in the Life science gardens during the dry Utah summer and …show more content…

The peat is more compact and almost had a woody texture. When wet this substitute was compact. Due to weekly observations I came to the conclusion that Giant Zinnias grow better and at a faster rate in a soil make of perlite or containing perlite. When we transferred our plants into larger pots I mixed perlite into a couple of the pods to see if it would effect the growing patterns compared to those only in peat. The flowers that were grown in a mixture are now taller, have larger leaves, and look healthier in color. It is possible that Zinnias respond better to perlite because it allows more oxygen flow and retains water better. Also because the Zinnias are used to humus based soils that are fast draining the perlite was a better fit for the
