Why do the flowers of the common zinnia grow taller, one after another?
Zinnia: annual herb. Stems erect, 30-100 cm tall, covered with strigose or long hirsute hairs. Leaves broadly ovate or oblong-elliptic, rough on both surfaces, densely short-strigose beneath, with three basal veins. Capitulum solitary at the apex of branches, involucre broadly campanulate; phyllaries in several series, broadly ovate or ovate-elliptic. Ray florets dark red, rose, violet or white, ligules obovate, apex 2-3-toothed or entire, short-hairy above, long-villous beneath. Disk florets yellow or orange, apical lobes ovate-lanceolate, densely yellow-brown tomentose above. Achenes of female florets obovate; achenes of disk florets obovate-cuneate. Flowering June-September, fruiting July-October.
Zinnia
Native to Mexico, it is a well-known ornamental plant, with single, double, curled-leaf, crinkled-leaf and various differently colored horticultural cultivars. It is widely cultivated throughout China, sometimes becoming naturalized. In January 2016, American astronauts successfully cultivated the first zinnia on the space station.
Landscaping:

Plant culture:
The zinnia has a very long flowering period, from June to September, with flowers opening in succession and keeping their bright colors for a long time, symbolizing everlasting friendship. Even more interestingly, the first flower of the zinnia opens at the top, and then the flowers at the tips of the side branches open higher than the first one, so it is also named "step by step higher".
The flowers of the zinnia come in a very rich range of colors. Grown as potted plants for their flowers, each one taller than the last, they inspire people to strive upward.
