Disappointment with this plant, it arrived with 4 yellow leaves. Planted immediately and watered almost daily for the past 3 weeks, no sign of recovery so far.

Description
Featuring an elegant upright foliage, strongly veined in a blue-grey colour, the 'Hosta 'Krossa Regal' is also imposing due to the size of its flower stalks. It is a very tall variety, with a beautiful upright, lanceolate foliage with 12 veins, in a blue-grey colour. It forms a clump of 1m (3.3 ft) in height and 40-50cm (15.7 - 19.7 in) in diameter.
In summer, during the months of August and September, pretty flowers appear in the form of small trumpets in shades of pink-purple. Standing at over 1.20m (3.3 ft) in height, the flower stalks, very slender, stand out remarkably well against the foliage and create a strong visual effect.
This perennial is not very demanding, it can be planted in large pots or in the back of flower beds... The hosta simply dislikes excessive drought. To be combined with other Hostas for beautiful visual effects or with Equisetum (horsetails) and Carex elata 'Aurea' to create a strong visual impact.

Planting and care
Hostas are planted in spring or autumn. Hostas prefer a deep, rich, humus-bearing, loose soil, preferably neutral to acidic (at least low in limestone), moist to wet throughout the year. Plant them in partial or dappled shade and sheltered from strong winds.
Prepare a planting hole of 20 cm (7.9 in) x 20 cm (7.9 in) x 20 cm (7.9 in). If your soil is heavy, mix equal parts of compost with crumbled soil, partially fill the hole, and place your potted plant so that the top of the root ball is covered with 3 cm (1.2 in) of soil. Adding a slow-release fertilizer will nourish your plant during its rooting period without the risk of burning. Make sure to position the base well above ground level. Firm the soil and water generously to eliminate air pockets. If the weather is dry, regular watering for a few weeks will help to establish your plant. Also, water regularly in case of a dry summer.
With their preference for moist areas, slugs and snails never stray far from hostas. Even though blue or variegated hostas often have thicker and tougher foliage, which is less appealing to slugs, these plants still need gastropod protection. Protect your Hostas by surrounding them with ferramol-based pellets, eggshells, coffee grounds, mulch, or any dry, rough natural substance that repels them. Hedgehogs are the best allies of gardeners in the fight against gastropods because, unlike chickens, they do not till the soil and do not attack the tender green shoots of young plants. Finally, a natural way to repel slugs and snails is to have companion plants with a repulsive odour, such as wormwood and garlic.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
