Blue variegated hostas
Variegated blue hostas are a sight for your eyes. You should definitely plant at least one of these in your garden.
There are several types of blue-variegated hostas. Let’s look at them individually.

Yellow and blue hostas
The second most popular variegated hostas are varieties with yellow leaves with blue in the middle. This is actually a very delightful combination of colors. They add variety to a garden because they are very striking and contrasting.
Another type is the blue-green hosta. They are not as noticeable as the previous ones, but the combination of blue and green looks very mysterious. When you look at the leaves of such varieties you get the impression that they were drawn by some unknown artist.
How to grow blue hosta?
To successfully grow a blue hosta, plant it in a loose, nutritious substrate in early spring. It is best if it grows in a shady spot. The spacing between blue hostas should be 1 to 4 feet.
The best soil for blue hostas is a mixture of native soil and organic matter. Use only quality organic matter from reputable suppliers.
Water blue hostas when the soil is 2 inches or more dry. Use about 1 gallon of water for each bush. Avoid overwatering as this can cause crown rot.
Blue hostas are best propagated by division. The best time to do this is the first half of spring. They can also be propagated by seed and leaf petioles.
The reason for blue hostas not growing can be pests or diseases. Use fungicides against diseases and horticultural oil or insecticidal soap against pests.
Blue hostas can be grown in pots. This is especially true for dwarf and medium-sized varieties. Use pots at least 6 inches across and deep to be successful. Make sure the pots have drainage holes.
Do blue hostas prefer sun or shade?
Blue hostas prefer full shade. The best sun exposure for them would be no direct sunlight at all. In this case, you can count on a deep blue color.
This type of hosta can also tolerate a few hours of direct sun but only in the morning or evening. Getting direct sun the blue color will be less pronounced.
Blue hostas absolutely do not tolerate full sun. If you plant them in a location with more than 4 hours of direct sun, they will burn. Large yellow areas will form on the leaves that will turn brown over time.
Are there really blue hostas?
Blue hostas actually have green leaves covered with a white waxy coating. The combination of these two factors gives the blue color effect. If you wipe off the wax coating, the leaves will turn green.
Hostas produce a waxy coating on their leaves to reduce moisture evaporation. This is how the plant survives periods of drought.
In addition, waxed leaves serve as a natural barrier to pathogens. Fungal and other diseases are much more difficult to parasitize on the leaves if they are covered with a protective coating.
Many other plants also have a waxy coating on their leaves, stems, and even fruits.
Why did my blue hosta turn green?
Blue hostas turn green from too much direct sun. In addition, some varieties turn green at the end of the season regardless of sun exposure.
Blue hostas start out green, but very quickly their leaves become waxy. As a result, the color changes to bluish or deep blue. However, in summer they can turn green if they get direct sunlight.
To keep blue hostas blue, provide them with full shade. You can do this by using a shading net. Also, good watering and nutrition help to maintain the blue color.
