Succulent plant-- the Queen of Violet

The Violet Queen is a small and medium-sized perennial succulent herb of the genus Elaeagnus in Sedum family. The leaves are densely arranged in the shape of a rosette, which turns into a dreamy purple and pink in strong light, and the edge of the leaf has a transparent ice edge. One of the parents is the moon shadow, and the other parent is unknown. There is no obvious dormancy period, and the growth is faster than that of other plants of the same genus. First in Santa Barbara, California? Cultivated by horticulturist Edward Orpet, its name is confused with blue stone lotus in New Zealand, and the information that one of its parents is blue stone lotus can not be confirmed.

Morphological features:

The leaf is oval lanceolate, the tip of the leaf tip slightly concave, covered with white powder, generally light gray green or light gray blue; when the light is sufficient and the temperature difference is large, it becomes more bright purple and pink (usually the brightest color in late autumn or winter). There are many leaves, arranged in a dense rosette shape, up to 20 in diameter. Perennial plants are densely grouped, 10-12 cm high, and each rosette can reach 15-20 cm in diameter. Florescence is spring, spikes, bell-shaped flowers, apex 5-lobed; petals inside yellow, outside pink.

Growth environment:

Violet Queen likes sunny, cool, dry, well-ventilated environment; resistant to semi-overcast, mild frost; avoid waterlogging, avoid hot and humid. Growth throughout the year, there is no obvious dormancy period, but the growth rate will slow down in summer. If the light is not enough, the leaves will grow too long, the red color of the leaves will gradually dim and the ornamental value will be weakened, while the plants growing in the sunny places will be short and strong, and the leaves will be arranged compactly and beautifully. The lowest temperature resistance is-6 to-3 degrees Celsius.

Cultivation techniques:

Watering too often will form stagnant water in the roots and cause plant rot, especially in hot and humid summer, you should pay more attention to watering carefully. Generally 2-4 times a month watering, follow the basin soil "dry thoroughly irrigated" principle. Fertilization should be controlled at 1-2 times a month; second, avoid splashing water on the leaves when watering, forming ugly water stains. High temperature in summer should be properly shaded and watering should be controlled in winter. The medium can be a mixture of peat, vermiculite and perlite, and an appropriate amount of base fertilizer can be added.

Pest control:

The common diseases are root pink scale, rust, leaf spot, root knot nematode and so on.

Plum rain season is prone to the outbreak of bacterial infection and decay, so it should be cultivated with well-breathable granular soil, avoid watering during exposure, and set up rain-proof ceilings to avoid waterlogging. Some fungicides can be sprayed every 10 days for prevention. In addition, the root pink scale will also break out with the slowdown of plant growth in summer, which can be controlled by spraying organophosphorus pesticides every 10 days or spreading carbofuran on the surface of the basin soil.

Rust and leaf spot can be sprayed with 75% chlorothalonil wettable powder 800 times, and root-knot nematodes can be controlled with 3% carbofuran granules. Black weevil can be sprayed with 500 times of 25% carbaryl wettable powder.

Methods of reproduction:

Leaf insertion: during the growth period, break off the well-growing and thick leaves and lay them flat on the wet sand, with the leaves facing up and back down, without covering the soil and placing them in a cool and ventilated place. Leaflets and whisker roots can grow from the base of the leaves in about 10 days, and the roots can be watered to promote their rapid growth and bury the roots in the soil. In the future, let it bask in the sun, properly water and fertilize, and it will gradually grow into a strong new plant. Cuttings: single leaves, tillering branches or top branches can be used. The cuttings cut are unlimited in length, but after the cut is dry, remove the lower leaves and insert them into the sand bed. It usually takes about 15 days to take root after insertion. Insert the soil should not be too wet, otherwise the cut is easy to yellow rot, the root length of 2-3 cm on the basin. Leaf cuttings can also be used.

Ramet: it is best to do it in spring. Cuttage propagation is commonly used. Indoor cuttage can be carried out in four seasons, especially from August to October, with fast rooting and high survival rate. Cuttings can be cut with single leaves, tillers or apical branches, and the length of the cuttings is unlimited, but the cut should be dried and then inserted into the sand bed. It usually takes about 15 days to take root after insertion.
