5. Cyanosis azure
Representatives of the genus Polymonium are surprisingly hardy perennials. Their pinnate leaves are more reminiscent of the best ornamental trees than traditional perennials. And the luxurious bloom surprises with its grace. Most cyanosis are summer stars, but cyanosis blue or azure wakes up early and just manages to catch the parade of early perennials.
Polemonium blue cannot boast of a large selection of varieties or decorative forms. The base plant is so beautiful and hardy that it is not often decided to look for more original alternatives to decorate the front garden.
But for a ceremonial effect and even greater catchiness, two candidates with slightly different characteristics can be considered. Firstly, a surprisingly beautifully illuminating composition and capable of overshadowing even the best ornamental shrubs - the cyanosis of the blue variegated form. Its strict white stripes on the leaves make them look like willows from afar. Secondly, the uniquely elegant snow-white alba form, which has a leaf tone slightly darker than ordinary cyanosis, is worth attention.
Polemonium blue is distinguished by its amazing plasticity. He not only perfectly adapts to places with completely different conditions, he spreads himself, becoming more and more beautiful over time, but is also able to slightly change his appearance depending on the conditions. Depending on where the blue cyanosis is planted, it can be limited to a modest half-meter size, and grow to more than a meter in height, in girth equal to the shrubs.
The fertility of the soil and the absence of vigorous competitors are especially favorable for reaching maximum sizes. The flowering time may also differ: depending on the weather, the plant can bloom in May or wait until June.
Polemonium azure is a powerful perennial with non-sod-forming, fibrous, thick and creeping roots. Erect and solitary, glandular-pubescent in the upper part, shoots in blues are surprisingly thin and persistent. The alternate leaves are very large, pinnate, with 5–12 lanceolate lobes. They are surprisingly evenly distributed along the stems and create a dense ornamental pillow, further emphasizing the spreading and grace of the plant.
At the tops of the shoots, brushes or panicles of inflorescences with bell-shaped flowers, with rounded lobes and stamens slightly protruding from the throat, bloom. Unique periwinkle colors or radiant white are the only color options for the inflorescences.
Unlike many other tall perennials, cyanosis does not seem to be divided into two tiers, with a flowering cloud floating above dense greenery, but is perceived as strikingly harmonious and delicate. The subtle grape aroma of straight cyanosis inflorescences is mesmerizing and seems especially amazing in spring.
Conditions for growth and care for azure blue
Cyanosis feel great in any cool place and high-quality fertile soil. They are equally good in the sun and in light shade. The only drawback of this plant is its love for high humidity. It is for this reason, when choosing places for cyanosis blue in the front garden, it is worth planting it along with flowering plants that require regular watering.
If there is a reservoir in the front garden, then on its shore the cyanosis will feel very good. Cyanosis is considered one of the plants that quickly lose its decorative effect after flowering, but this statement is not entirely true: it can decorate areas until late autumn, if you take care of the mandatory pruning. After flowering, the cyanosis can be cut off (slight shortening of the shoots or a lower cut allows you to control the height of the bushes), and the cyanosis will bloom again no less effectively.
