In 1855, the first attempts were made to obtain blue roses. Breeders managed to breed several species that have blue petals. And then they occasionally acquired blue shades if they were grown in certain conditions. Much later, in 1909, the Veichelblau variety was obtained, and in 1974 two more appeared - Charles de Gaulle and Blue Moon. Unfortunately, they had only lilac, lilac tones, which only from a distance resembled blue. Only in 1978 was the Blue Parfum variety created and a little later in 1984 the German Blue river variety appeared. Finally, the flowers began to resemble real blue roses. And in 2009, Japanese scientists were able to breed flowers with bright blue petals.

Now in the world there are a large number of varieties called blue roses. They have flowers in various shades: lilac, lilac, lavender, burgundy. Only for a certain period of time their petals turn blue. The most famous species are listed here:

Blue roses prefer light, fertile, humus, air-permeable, loose soils, neutral, slightly acidic (loam). If heavy earth is added sand, compost, ash.

Flowers are planted at a distance of 1 m. From shrubs, to large trees - 2 meters. Can be grown in a greenhouse.

Dig a hole for planting a plant 2-3 times larger than the roots of the bush. Drainage is poured at the bottom, fertilizers are placed, filling the pit by half, then the garden soil.

Planting a rose

The roots are pre-soaked (for 2-3 hours) in a growth stimulator (Kornevin, Heteroauskin). A seedling is planted, sprinkled with earth, tamped, moistened with warm water.

  • saltpeter (2 gr.);
  • urea (1 gr.).

Fertilizer urea

They are fed with potassium-phosphorus substances during the period of bud formation. During flowering, fertilizers containing magnesium, sulfur, potassium, phosphorus are used.

In autumn, nitrogen, potash, phosphorus fertilizers are applied 2 times. You can alternate mineral mixtures with organic substances. They use liquid mullein, chicken droppings, ash.

Plants are systematically weeded from weeds, they loosen the soil around the boles, mulch with peat, dry manure.
