Polyantha Roses
Polyanthas are, perhaps the most truly everblooming of all Roses, being scarcely ever out of flower during the whole growing season... They are especially valuable for massing, edging, and to some extent for mingling with other flowers.
Rudolf Kluis. (Kluis & Koning, 1921.) Vermilion buds and flowers in large clusters. Strong, bushy growth and a constant blooming habit.
It came out the same year and seems to be identical with Lady Reading.
