The main flower varieties in production are chrysanthemums, hydrangeas, gerberas, and asters. Their next few meals will consist of nectar from daisies, chrysanthemums, and asters. Plant families with epigynous flowers include orchids, asters, and evening primroses. Herbaceous weeds, mostly annuals such as asters, evening primroses, and milk weeds, invade the rock. They are most often found in plants of the family Asteraceae (daisies, asters). Plant life at the park includes dame's violet, goldenrod, spring beauties and asters. Meadowflowers included goldenrod and asters, rampant spreaders from North America long familiar in English gardens. They have also been observed foraging on introduced asters, such as yarrow and Canada thistle. Flowering plants include the dwarf desert poppy and a variety of asters. The station is also involved in the floricultural of rose, asters, gladiolus and orchids. Other wildflowers in the park are asters, elephant's-foot, wingstem, and yellow jewelweed. Fall brings its own mix of wildflowers, including many asters and goldenrods. The herb layer is fair to excellent cover of grasses, goldenrods, and asters. A number of plants have stoloniferous rhizomes including Asters. Asters can grow in all hardiness zones.
