Lupine: plant description
It is a perennial plant popularly called the "wolf bean". Some species are grown as an annual plant. Lupine can reach a height of 50 cm. The stem is erect, branched. There are a large number of varieties that are decorative.
The most popular varieties are: Minaret, Fireworks, Lulu, Russell, Apricot. Flowering begins in May or June with bright clusters.
The color of the inflorescences can be different: sunny yellow, pink, lilac, purple, blue. Perennial lupins bloom only in the second year. The leaves of the plant are palmate-complex, alternately green in color. Perennial lupins have a powerful root system, so the plant is resistant to drought and frost.
Collection of planting material
At the end of flowering, a few dry inflorescences should not be removed. From them, you can get seed. The pod should be dark and dry. It is advisable to collect seeds in sunny weather. If the collection of seed material is carried out in damp weather, then they will begin to rot.
The seeds are removed from the pod, laid out on paper and left to dry in a warm place. Avoid direct sunlight. Then pour into a glass container and store until sowing. In addition to a glass jar, you can use tissue or paper bags.
Preparing seeds for planting
Before sowing seeds into the soil, they need to be prepared. For this, scarification is carried out. This process consists in disrupting the integrity of the seed coat. The procedure promotes rapid germination and increased germination. There are several ways to scarify.
Mechanical scarification. It consists in mechanical processing using sandpaper, river sand, blade, etc. Take a handful of seeds and grind with coarse river sand or rub between sheets of sandpaper. During the procedure, it is important not to damage the embryo. After the end of scarification, the seed is soaked.
Thermal scarification. Fold the seeds into cheesecloth, put in the refrigerator for a few minutes, and then pour over with boiling water. You can first dip the gauze bag with seeds in boiling water, and then in cold water. Exposure to high and low temperatures is beneficial. The procedure should be performed 2-3 times. Seeds that have a burst shell are removed from the bag, and the rest continue to be processed.
Chemical scarification. The procedure involves soaking the seeds in special chemical solutions. For this purpose, chlorine solution or potassium permanganate is used. For 200 ml of water, 2-3 drops of the solution are needed. In this case, the seed is placed in a chlorine solution for 10 hours, and a solution of potassium permanganate for 15 minutes.
These methods are applicable to self-harvested seeds. In stores, they usually sell ready-made scarified seeds.
Sowing seeds into the ground is carried out after the snow melts. The optimal time for this is April. Many growers plant seeds for the winter. This is usually done at the end of October. These are the most suitable conditions for a plant. Before the onset of spring, the seeds will ripen and germinate quickly. Seed material is deepened into the soil for a couple of centimeters and lightly sprinkled with peat. When planting, the distance between seedlings should be 5-10 cm.

In the fall, it is necessary to prepare a site for sowing seeds. Lupine loves sandy loam or loamy soil. If the soil is acidic, then lime or dolomite flour must be added. You will need 5 kg of the specified substance per square meter. Lupine does not like alkaline soils. To make the soil slightly alkaline, peat is used.
In regions with a cold climate, sowing seeds for seedlings is performed at home. The procedure is performed in early spring in order to have time to plant seedlings with the onset of warm days. When growing seedlings, it is necessary to prepare boxes and make drainage holes in them. Next, place the soil mixture, which will consist of 2 parts of turf and peat and 1 part of sand. Deepen the seeds slightly and cover with foil. You can plant seedlings in open ground at the end of April if the weather has become warm.
Features of plant care
It is advisable to grow lupine in a sunny area. At first, the plant should be weeded regularly, loosen the soil and remove weeds. In the future, adult plants are spud. For lupines, it is necessary to equip supports as they grow, as the wind can break them.
It is also necessary to regularly remove faded buds and dried leaves. This procedure will extend the flowering time of the lupines. In addition, it protects against self-seeding. Water this ornamental plant often, but in moderation. With the onset of warm summer days, you need to water more abundantly.
Before preparing for winter, peduncles and damaged leaves are removed, the soil around the plant is mulched. If the varieties of lupine are characterized by weak frost resistance, then it is recommended to cover the plants. After 5-6 years, the lupine must be removed, since the plant is aging and young seedlings should be planted in its place.
Lupine is not picky about leaving. Observing all the indicated recommendations for growing and caring for a plant, you can admire these beautiful decorative flowers for a long time.
