Flowers that bloom first and then grow leaves.

Many plants grow leaves first and then bloom, but some plants bloom first and then grow leaves. This feature also adds a lot of points to its ornamental value, so how do these plants grow after flowering, and what are the more common plants that bloom first and then grow?

Magnolia (details)

For those plants that grow leaves first and then bloom, the temperature required for leaf bud growth is relatively low, and the temperature in early spring has already met its growth needs. So it grows leaves. However, those plants that bloom first and then grow leaves are the opposite. The temperature required for flower bud growth is relatively low, while the temperature required for leaf bud is relatively high. After the flower buds grow and bloom, the leaf buds are still lurking, and leaves will only grow when the temperature rises further.

It can be seen that whether plants bloom or grow leaves first is mainly determined by the different requirements of flower buds or leaf buds on growth temperature.

Plum blossom, winter jasmine, wintersweet, magnolia grandiflora (detailed introduction) and other flowers bloom first and then grow leaves. The reason for this phenomenon is that their flower buds differentiated in the summer of the previous year, and after forming, the flower buds entered a dormant period and could bloom in the spring of the following year. At the same time, because the temperature required for the growth of flower buds of these flowers and trees is lower than that required for the growth of leaf buds, in the case of low temperature in early spring-the flower buds are long and open, and the leaf buds begin to sprout and spread after the temperature rises, thus forming the phenomenon of flowers first and leaves later. If the temperature required for the growth of leaf buds and flower buds is similar, flowers and leaves will bloom together.

There are mainly these plants that bloom first and then grow leaves:

Magnolia, kapok, plum, elm, magnolia, Populus euphratica, birch, weeping willow, Yingchun, Yang Shan, paulownia, konjac, wintersweet, seabuckthorn, Wanhua, peach, wisteria (details), bauhinia, rhododendron, begonia, forsythia, hazelnut, Populus tomentosa, wintersweet, plum and so on.
