Different species

This is the most fundamental difference. It is this difference that determines all their differences. The first plant belonged to one year old species of Erigeron, while the second species was baijiu. Moreover, the first type of plants is annual or biennial, while the second is mostly annual

Different appearance

Although this difference is not easy to see, if you look carefully, you may still find their subtle differences. The first is the length of their stems. The length of the stem of a year's canopy is generally 40-80cm, with a diameter of 2mm to 4mm, while the length of the latter stem is 50-100cm, which is generally higher. There is also the difference between their flowers. First, there are subtle differences in color. The first kind of flowers may be white or light blue, while the second kind of flowers are almost white. In addition, the central bisexual flowers of the first kind are tubular, while those of the second kind are tubular. Of course, these differences are not very obvious and need our careful observation

The period of flowering and fruiting is different

There are slight differences in this period, but the gap is not much. The former blooms from June to August and bears fruit from August to October. The latter blooms from June to September, the fruit begins to mature in July, and the peak of reproduction is in October

Different hazards

Their harm is very serious. However, they are hosts of different pests
