Petals in 4 whorls, mostly formed by natural increase of petals, petal margin lobed or entire, occasionally a few lower stamens of gynoecium petalized, petals 10-23, pistil normal, seed setting rate very high. The double petals are yellow, red, orange and so on.

3. Sparse ball type

The petals are more than the compound petals, the stamens degenerate, the pistils are normal, and the inner petals fold inward. The petal number is 20 to 26, forming a sparse ball type, and the seed setting rate is high.

4. Dense sphere type

Most of the outer petals are naturally enlarged, while the inner ones are pistil petals and colored petals. Stamens degenerated completely, petals 25-37, multi-layer folded, closely arranged, spherical to ellipsoidal, and the seed setting rate was very low.

5. Crown type

The outer valve is broad and spreading, most of the stamens are petalized, the stamen petal is mixed with small bundles of stamens, and the stamen petal group is towering; or only the upper part of the stamen column is petalized, and part of the outer valve is folded, still forming a towering shape, similar to the crown.

What are the methods of raising seedlings of hollyhock?

1. Sowing time

Hollyhock can be sown in spring and autumn, but since the seed germination temperature is about 21 degrees, and it takes three months after sowing to blossom, if sowing in autumn, hollyhock cannot blossom when the temperature is low in winter, so most of the northern regions adopt spring sowing to breed hollyhock. On the other hand, in the southern region, because of the short interval between spring and summer, it is easy to die if the spring seedlings are sown in high temperature in summer, so they generally choose to sow in autumn.

2. Soil treatment

If it is a family land cultivation, it is best to choose the slope with sufficient light in the hospital, which is good for drainage. After selecting the land, the soil should be turned over deeply. Because it likes more fertile soil, it is necessary to dig a hole around the turned soil and bury an appropriate amount of rotten sheep manure or chicken manure as base fertilizer.

3. Sowing method

After leveling the land, you can bury a seed every 30cm, or you can put a seed directly in 30cm, and then sprinkle a layer of fine sand or soil on top of the seed. The thickness of the soil is about 0.5-0.8 cm, which is not easy to be thick, otherwise it is not conducive to germination and will lead to mildew of seeds.

4. Transplant into the pot

Transplanting in the pot can be carried out when the seedlings of hollyhock grow to about 5 cm, or when they grow to about 10 cm. When transplanting, first fill the soil into the flowerpot according to the way of direct seeding in the previous pot, and then use the seedling opener to dig out the seedlings together with the soil and plant them in the flowerpot, and the surrounding soil is slightly pressed, and then pour through the root water and put it in a ventilated hiding place for 3-5 days and then move to a place with sufficient light for maintenance.
