1. morphological characteristics

frangipani rubra (pictured) is a perennial arborescent succulent plant. Plumeria rubra is large, with a plant height of 5m, many branches and thick branches; Leaves alternate, mostly clustered at branch ends, oblong or broadly lanceolate; Flowers are terminal, cymes, corollas funnel-shaped, convoluted and imbricate, with a flower diameter of 7-1cm, pink or yellow, and fragrant; The flowering period is from May to November.

2. Growth habit

Plumeria rubra mostly grows in an environment with sufficient sunlight, fertile and humid soil and good drainage, and is slightly resistant to shade, drought and waterlogging. The most suitable growth temperature of safflower plumeria is 2-35℃, and it is vulnerable to freezing injury below 5℃.

3. Cultivation and maintenance

Plumeria rubra does not need shade in summer, but is maintained indoors in winter. Watering is based on the principle of "no watering, no watering at all, no water accumulation". The soil should be kept moist during the growth period, and watering should be controlled during the dormancy period after flowering. Turn over the pots and change the soil once a year before germination in spring, or apply calcium-rich organic fertilizer containing rotten egg shells, fishbones and broken bones.

4. Propagation method

Plumeria rubra is propagated by cutting. Under normal circumstances, cutting propagation is mostly carried out in the middle and late May. The specific operation is to cut branches with a length of 2-3cm from the branch base of the safflower plumeria. Because white milk will flow out from the cut of the plant, it is necessary to put the branches in a cool and ventilated place for 2-3 days, and then cut them when the wound is covered with protective film. Remember: if the branches with milk are directly cut, the roots are easy to rot. It is necessary to cut branches into clean vermiculite, sand bed or shallow sand basin, and then spray them with water moderately, and put them under indoor or outdoor shade, and spray water once every two days to keep the culture soil' moist'.
