Produktbeschreibung
Featuring luminous, ice-white petals arranged elegantly around a soft, pale yellow centre, this pristine selection practically glows in low-light conditions, making it a staple for twilight or "moon" gardens. The pure, clean colouration is frequently utilised by landscape designers to visually cool down brightly coloured, aggressive planting arrangements and provide a resting place for the eye. The bright white, saucer-like blooms open wide, creating a highly visible, towering column of light.
The tender, emerging shoots of this specific plant are highly attractive to nocturnal pests, you must maintain a clear, debris-free zone around the base to eliminate dark, damp hiding spots for slugs and snails. Avoid planting this variety in dense, heavy soils, as the taproot requires loose, friable earth to establish the necessary foundation for its towering height. As the flowers fade from the bottom up, meticulously snip off the dead heads with sharp scissors to keep the white column looking sharp, pristine, and free of brown, decaying matter.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.
Größenberater für Gartenpflanzen

Pflanzen in größeren Töpfen sind oft mehrere Jahre älter als Exemplare in kleineren Gefäßen und verfügen über ein bereits besser ausgeprägtes Wurzelsystem sowie dichteres Laub. Dadurch entwickeln sie sich im Garten deutlich schneller zu einer stattlichen Pracht als kleinere Alternativen.
Die gängigsten Topfgrößen für Gartenpflanzen sind 9cm, 1L, 3L und 5L – diese Angaben beziehen sich auf den Durchmesser am oberen Topfrand oder das Fassungsvermögen.
Pflanzen im 9cm-Topf sind nach wie vor die beliebteste und preiswerteste Option. Hier ist lediglich etwas Geduld gefragt, bis die Gewächse nach dem Auspflanzen ihre volle Größe und Reife erreichen.

Anleitung
Profi-Tipp
Plant this luminous white variety against a dark backdrop to make the pale blooms stand out dramatically. Avoid planting it in cramped corners where poor air circulation invites powdery mildew. Thinning out some of the basal leaves on the Alcea Polarstar improves airflow around the crown significantly.
Richtig gießen
Provide extra hydration during prolonged periods of dry weather to keep the leaves from wilting. Focus your efforts on the surrounding soil rather than the Alcea Polarstar itself. Consistent hydration helps the pure white flowers maintain their luminous quality without browning at the edges.
Richtig pflanzen
Ensure the planting area is completely free of large rocks or debris that might impede root growth. Mix a balanced granular fertilizer into the soil at the bottom of the hole for a gentle nutrient boost. Firm the ground around the stem with your heel to anchor the Alcea Polarstar securely.
