A superb young plant. With the very (too?) mild temperatures at the start of this year, the hosta started back into growth as early as February and is developing magnificent leaves. I'm delighted.

Description
Hosta Waterslide is a variety as unusual as it is charming, with its frizzy blue foliage that retains its beautiful colour throughout the growing season. It is a medium-sized hosta, with low and wide growth composed of long pointed leaves, strongly undulated at the edges and thick enough to discourage slugs. From this somewhat extravagant vegetation beautiful lavender flowers emerge in late summer. Whether planted in the ground or in pots, this perennial will catch the eye. Place it at the edge of a woodland scene, in a contemporary or Japanese-style bed, always in shade or partial shade, planted in moist but well-drained soil.
This Hosta, or Funkia Waterslide is a fully hardy perennial from the lily family or the hosta family depending on classifications. The plant shows a spreading dome-like habit from spring onwards. When matured in 5 or 6 years, it will reach a height of 35cm (14in) and can spread up to 80cm (32in) if the conditions are right. It is a long-lived variety, with narrow lanceolate-shaped leaves that taper to a point. The lamina is very thick, with well-visible parallel veins and strongly undulated edges. Flowering usually takes place in August-September, in the form of elongated and pendulous bells, clustered towards the top of 42cm (17in) peduncles that emerge from the foliage. This perennial slowly spreads through stolons, similar to strawberries. All above-ground deciduous vegetation disappears in winter.
Hostas are traditionally planted under deciduous trees, in moist beds or rockeries, and especially near water features. It is a perennial that can be grown in pots and even as a standalone plant. Hosta Waterslide pairs well with ferns, heucheras, caladiums, and astilbes, for example, as these plants thrive in similar environments. To highlight its extraordinary foliage, combine it with yellow to golden coloured ornamental grasses, preferably Carex and Hakonechloa. Also consider spring bulbs, brunneras and creeping bugles as companions for this plant.

Planting and care
Hostas are best planted in spring or autumn. Hostas prefer a deep, fertile, humus-rich, loose soil, preferably neutral to acidic (at least low in limestone), moist to wet throughout the year. Plant them in partial shade or dappled shade, and in a sheltered location away from strong winds.
Prepare a planting hole of 20cm (8in) x 20cm (8in) x 20cm (8in). If your soil is heavy, mix half compost with crumbled soil, partially backfill the hole, and place your potted plant so that the top of the root ball is covered with 3cm (1in) of soil. Adding a slow-release fertiliser (such as bonemeal) will nourish your plant during its rooting period without the risk of burning. Make sure to position the collar well above ground level. Firm the soil and water thoroughly to eliminate air pockets. If the weather is dry, you will need to water regularly for a few weeks to facilitate the establishment of your plant. Also, water regularly in dry summers.
With their common 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 appetising to slugs, these plants should be protected from gastropods. Protect your Hostas by surrounding them with crushed eggshells, coffee grounds, wood chips, or any dry and rough natural substance that repels them. Hedgehogs are the gardener's best allies in the fight against gastropods because, unlike chickens, they do not till the soil and do not attack the young green shoots of young plants. Lastly, some plants have a repellent odour for slugs, 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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
