Which flower seedlings have prospects and high economic benefits?

Influenced by market factors, there is a strong demand for large-scale fine trees, but there are not many seedlings, and many areas are out of stock. For example, Sophora japonica, Cinnamomum camphora, Luan tree, Zelkova schneideriana, Sapindus mukoraiensis, Pu Shu, Platycladus orientalis, Jacaranda, Qiu Feng and other 12~20 cm fine products have increased sales and prices, and the current market demand exceeds supply. The average prices of Sophora japonica, Fraxinus mandshurica and Zelkova schneideriana with DBH of 15 cm are about 1200, 1600 and 2000, while Huangshan Luan with DBH of 12~ 16 cm is basically out of stock.
