Red varieties in different shades and flower forms — one colour family.
Blue, lilac and silver neighbours highlight the red:
The variety was forced in pots for Mother's Day, so almost literal names took hold in different languages:
Where to plant. The low, compact bush suits borders, the front of a mixed border, pots and containers, which is exactly how it was traditionally grown and sold for Mother's Day.
Climate. Roughly USDA zone 5–6 (about −29 °C); polyanthas are generally hardy, but in Ukraine light winter protection would be safer.
Care. Standard care for polyantha roses. There are few garden data on disease resistance; the only known weakness is susceptibility to spider mites during greenhouse forcing.
Name. 'Mother's Day' (Danish 'Morsdag', German 'Muttertag'). The variety was traditionally forced in pots for this holiday, hence the name.
Breeding. Bred by the nursery F.J. Grootendorst (the Netherlands) in 1949 as a sport (mutation) of the polyantha rose 'Dick Koster'.
Significance. A historic pot and border polyantha rose with small red pompom flowers. The red form is the original; the white, orange and pink sports later arose from it.
The cultivar’s reference temperature is −29 °C (USDA zone 5–6). Overwintering depends on the conditions. About −29 °C; Ukraine: light protection.
Abundant, in waves, from May to the first frosts.
30–70 cm tall.
No data; typically full sun.
Sources differ in their assessment, from light to more noticeable; roughly light to moderate.
