The slow-growingHosta ‘Halcyon’cultivar is one of the best and most popular in its group known for blue leaves.
The waxy texture of the leaves resembles that of seersucker fabric.
Plant fast-growing hostas in the early spring or early fall, but not when it’s too hot outside.

If planted in partial sun, halcyon will need extra water.
If planted under trees, they require more water to compensate for the moisture absorbed by surrounding tree roots.
Hostas usually do not require division unless you want to propagate more plants.

Light
Hostas as a group prefer to be planted inpartial shade to full shade.
Water
Hostas prefer consistent moisture but will tolerate somewhat dry soil better than constantly wet soil.
Temperature and Humidity
Hostas do quite well in the climates in their hardiness zone.

They might wilt in very warm temperatures unless frequently watered, and high humidity sometimes encourages snails and slugs.
Hostas are sensitive to cold and will succumb to the first frost.
They do not emerge in the spring until the soil has warmed considerably.

Plants in this group are generally large-leaved cultivars with blue-green or grayish-blue leaves.
Hosta roots are very tough, and division can be difficult, especially if the soil is very wet.
Therefore, most choose to propagate hostas through division, which is a much more reliable method.
Remove the mulch when temperatures warm up in the spring.
This is disfiguring and unattractive, but it rarely kills a plant.
These pests can be baited to collect them for removal.
Keeping the ground free of thick mulches can also discourage slugs and snails.
Hosta is not deer resistant, and the foliage is quite a favorite meal for them.
Be on the lookout for these signs and learn what they mean.
This typically means that the plant is suffering fromanthracnose, a fungal disease.
The leaves become tattered.
Remove damaged leaves and divide plants to give them better air circulation.
You will need to remove and place the affected plants in the garbage.
It may be difficult to treat this problem with pesticides.
The blue tint seems to fade faster in brighter sun.
With the right care, most hostas can live up to 30 years or more.
Hostas are typically not grown indoors.
Eventually, you’ll need to consider dividing your hosta to save space and moving the divisions outdoors.
Never allow the hosta to sit in full sunlight.
A halcyon hosta is somewhat compact.
It can grow 18 inches tall and 36 inches wide.
