About the name
Name. “Roseberry Blanket” = “berry-pink blanket”. The name combines “rose-berry” (berry-pink, like raspberry or blackberry) and “blanket” — it captures the character of the variety: a landscape groundcover with a purple-raspberry colour.
Breeding. Bred by Reimer Kordes at W. Kordes' Söhne (Sparrieshoop, Germany). Code KORtwente (another internal code: KO 91/2520-01). Introduced 1991. Parentage not published. The Vigorosa® series is Kordes' line of landscape high-resistance varieties (Pink Vigorosa, White Vigorosa, Lupo, Innocencia). A common myth in catalogues: sometimes it is attributed to Mehring 1999 — this is wrong; the true data are Kordes 1991.
Significance. One of the key varieties of Kordes' Vigorosa® series — the flagship landscape shrub line of the 1990s. 4 synonyms in different markets: Roseberry Blanket, Purple Kiss, Raspberry Balconia®, Raspberry Blanket, Raspberry Vigorosa™ — typical for Kordes' landscape series. Very high resistance, 5/5 — typical for Vigorosa®. A unique fuchsia-purple colour — rare for groundcovers (most are pink or white). Heat- and drought-tolerant — good for southern regions. An ADR mark is not documented specifically for this variety, but the Vigorosa® series is positioned as an ADR-quality range.
