Family Protein. Homeland - Australia. More than 30 species of small trees and shrubs are widespread in nature.
- Adenanthos Detmolda Adenanthos detmoldii is a short bush 1.5-1.78 m in height, leaves are sessile, spirally located on the stems, gray-green, linear, young pubescent, smooth with age. Flowers are tubular, pale yellow or orange, pubescent, solitary, axillary.
- Coastal Adenanthos Adenanthos sericeus is a short tree, reaching 2-2.5 m in height, leaves are sessile, gray-green, thin, like needles. The trunk and young leaves are silvery pubescent. Flowers tubular, dark red, pubescent, solitary, axillary, can appear throughout the year.
In the photo, young plants in pots, with age, adenanthos grows, forms a very lush bush, branching well from the ground itself, so that the main stem is not visible. It tolerates transplanting and pruning well.
Caring for Adenanthos
Temperature: Normal in summer, optimally 25-28 ° C, in winter cool at 14-15 ° C, at least 10 ° C. In winter, in normal home conditions (a heated room), adenantos suffers greatly from dryness, heat, and lack of light.
Lighting: Adenantos likes bright, diffused light (shaded in the summer at noon hours). Grows well on east, west windows or next to the south window.
Some species, for example, Adenanthos terminalis, cuneatus, require full sunlight, in nature they grow in open areas. And since there is always less light in winter, these species may require additional lighting.
Watering: The soil should be evenly moistened, have time to dry well between waterings. Adenanthos prefer watering with soft filtered water. Do not tolerate waterloggedness in a pot or complete dryness during the growing season. In winter, in cool conditions, before watering the plants, touch the ground with your finger, make sure it is dry. Water little by little, so that the soil dries out in 3-4 days no longer.
Air humidity: Likes high humidity, can be sprayed. In winter, when the temperature drops, they do not spray, and watering is significantly limited. If you leave the adenanthos to winter in a heated room, you need to protect the plant from batteries with a screen (made of glass) or film. Place on a wide tray of water or hang the battery with a damp terry towel.
Fertilizers: For feeding during the growing season, fertilizers are used the same as for azaleas and gardenias. Top dressing is carried out every 3-4 weeks.
Transfer: Annually in the spring. The soil mixture is a weakly acidic or acidic reaction pH 5.0-5.5, from peat or leaf soil, sand, vermiculite, fine expanded clay or gravel chips, you can add pieces of pine bark. Drainage also needs to be done at the bottom of the pot.
Adenantos is a plant from the Southwest of Australia, where almost all species grow on sandy-stony soils, require good drainage in a pot, and easily rot and die when waterlogged. Only the species Adenanthos detmoldii and Adenanthos obovatus grow in swampy areas, love abundant watering and high humidity. But abundant watering does not mean stagnant water in the pot.
Adenantos is propagated by seed. This process is quite complicated. The problem is that the seeds of adenanthos have a dense hard shell, they need scarification - filing or complete removal of the shell. In industrial greenhouses that grow adenanthos and other plants for sale, the seeds are completely cleared of the seed coat. Then they are placed in a sterile medium (agar, vermiculite or filter paper). The entire process is carried out meticulously, by hand using a scalpel, tweezers and a microscope. For better growth, treatment with gibberellic acid (concentration 25 mg / l) is added - this promotes germination. With this technique, the germination rate is 70%. With conventional sowing, much less.
The seeds are kept quite well and remain viable for 2-3 years. Ideally, the seeds of adenanthos should be stratified - stored in wet sand or vermiculite, at about 10 ° C (refrigerated) for 2 months. In February-March, you can sow in a mixture of sand and peat (sterilize the substrate). Keep the sowing dish at a temperature of 20-25 ° C, with regular ventilation and maintaining a moderate soil moisture.
