What is the difference between sunflower and chrysanthemum

What is the difference between sunflower and chrysanthemum

1. Sunflower

1. Root

Its roots can penetrate deep into the soil, up to 100-200cm deep. Its lateral roots grow horizontally, with many fibrous roots and root hairs. Its root system is relatively developed and is widely distributed in the soil. Its roots grow even faster than the stems, especially when the flower disk is formed. When the seeds mature, the roots will stop growing and will wither.

2. Stem

Its stem is upright, with bristles on the surface and is relatively rough. In the later stage, the stem will become lignified and the inside will become hollow. Its embryonic stem has different colors, which is a very important way to identify its variety. The stem heights of its different varieties vary greatly. Even for the same variety, the heights can be different due to various environmental reasons.

3. Leaf flowers

It has two cotyledons and true leaves in pairs, growing in the area 1-3 nodes below the stem. The true leaves can grow relatively large and have bristles on them. The flower grows at the top of the stem. Its color and size are related to the variety. Its color is very attractive to insects for pollination. Its fruit is edible melon seeds. The seeds are relatively long, usually with black and white stripes, and the skin is relatively thick.

2. Chrysanthemum

It likes sunlight and dislikes shade. It can tolerate drought and dislikes waterlogging. It can withstand severe cold, and even in winter, its roots can survive the cold winter underground. It can withstand slight frost, but the seedlings need relatively high temperatures during their growth period. The best temperature is 20℃, the hottest should not exceed 32℃, and the lowest should not be lower than 10℃. It likes thicker soil with more humus and better water permeability. It can grow in slightly acidic to neutral soil. The best pH is within the range of 6.2-6.7.

3. Difference

Although both are yellow, the difference is very obvious. The flowers of chrysanthemum are thinner and longer, while the flowers of the former are thicker and larger. The flowers of chrysanthemum spread out continuously, while the former only has petals on the edge of the flower disk. Moreover, it is difficult for us to see the stamens of the latter, but the stamens of the former can not only be seen clearly, but also the seeds on them can be seen. The leaves of the latter are smaller and serrated, while the leaves of the former are wider and have small teeth on the edges.
