What tree species is better for grafting Osmunda japonica?

Grafting can only be carried out in the same family, preferably a family. Only 60 species of Lysimachia christinae are rare. Lagerstroemia speciosa is woody, so you should choose woody. Lysimachiaceae includes Lysimachia crassipes, Lysimachia villosa, Lycopodium, Amaranthus, Lagerstroemia speciosa, Lagerstroemia speciosa, Lagerstroemia indica, Lagerstroemia indica, Lagerstroemia indica, Daphne, and a good variety of Lagerstroemia speciosa can be grafted, which is quite good.
