1、 Ligustrum lucidum

1. Advantages: because it and Osmanthus fragrans belong to Oleaceae, it is also genetically similar, which provides a great possibility for grafting. After grafting with Ligustrum lucidum, the scion is easy to grow, and the probability of survival can be guaranteed

2. Disadvantages: it is easy to cause top heavy and thin roots. Because the roots are not very developed and may be hindered in later growth, the survival life is not long, and potting is not easy. And the flowering time is relatively late, the number is small, and the flower color is not thick, which looks relatively light

2、 Tassel

1. Advantages: in the north, this tree species is generally used as the rootstock for grafting, with good affinity, high survival rate and good growth in the later stage. It can shorten the time from planting to flowering and open flowers early. And it doesn't need to be trimmed often. It's much easier to manage and can save time

2. Disadvantages: because they are male and female plants, it will be inconvenient to keep seeds or collect seeds in the later stage
