The Australian kangaroo flower, also known as the kangaroo claw, belongs to the high-grade cut flower variety and is native to Australia. Let's take a look at his cultivation method.
Australian kangaroo flowers are perennial herbs with a half-wood base. Stems slanted, 20-40cm long, green stems, old stems reddish brown; single leaves, opposite, ovate, ca. 3–4cm long, apex acute, fleshy, leafy green, back The veins are red; the flowers are solitary in leaf axils, ca. 2–3 cm long, sepals 5, corolla many lip-shaped, lower inflated, apex 5-lobed, orange-red, lobes yellow, lobes red; stamens 4, inserted in On the petals, the anthers stick together; one pistil. Capsule, similar to Scrophulariaceae plants.
Like high temperature, high humidity, negative environment, if it is placed in the sun for a long time, too dry or too cold in winter will cause leaves. Goldfish flowers are most likely to defoliate in winter, which is related to temperature. The growth temperature of goldfish flower is 18-22 °C, avoid low temperature. If the temperature is lower than 10 °C for two consecutive days, the leaves begin to turn yellow and dry, and will defoliate until very slight vibration. In addition to the low temperature, the temperature will continue to exceed 30 ° C, and the leaves will also fall. In the summer, the goldfish grows slowly or almost stops growing. At this time, shading measures should be taken to make it grow vigorously and not to defoliate.
Common varieties: introduced in recent years are: C. microphylla, also known as button goldfish, produced in Costa Rica. The stems are slender and branched. Leaves opposite, leaflets. Flowers single leafhopper, orange-red. Flowering spring and summer. Fine leaf goldfish flower C.stavanger. Also known as the Starfish, a hybrid of Norway. Sprawling, overhanging. The flowers are large and many, reddish, and flowering in winter and spring. C.magnifica, also known as the whale flower. Production in Costa Rica, Panama. Stems erect, branches hairy. Corolla scarlet. In addition, there are varieties of bulbous goldfish, hairy goldfish, Adam goldfish and so on.
Seeding, germination temperature is 13-18 ° C, seed life is shorter. It can also be divided into plants. Growing in sunny places. Semi-cold resistant, need to be cold in the cold room (above 0 °C), keep dry in winter. The culture soil is used, and 3 parts of humus soil, 1 part of garden soil and 1 part of sand are mixed. Apply compound fertilizer once a month to provide sufficient moisture during the growing season and keep the soil well drained. Cover protection in autumn and winter.
Mainly cutting propagation, cutting survival rate is high, can cut strips of branches, each section about 8 cm, the upper leaves are cut off half, the lower part is cut off, keep the semi-shade moist environment, roots can be rooted in about 30 days. It can also be propagated by the ramets method. In the early spring or late autumn, each plexus must have 1 to 2 buds, and 2 to 3 plants per pot.
After the flower, all the weak branches, the top branches and the long drooping branches should be pruned. When the winter leaves, the withered flowers stems are cut off from the base and kept dry, which is beneficial to the growth of the new flowering branches in the spring. The substrate soil for cultivation of humus soil, manure and sand in a ratio of 3:1:1 is used, and the pH is 6 to 6.5. Apply a thin compound fertilizer solution every month. Apply phosphate and potassium fertilizer once every half month for the first two months of flowering. Change the basin once every other year.
