‘Nathalie Nypels' Short   Pink  Remontant    P2   H2  **
This excellent pink rose is one of the best for continuous flower, although its blooms are rather small and thin. It has quite the touch of the China Roses about it, and some people class it with them. The parentage is given as 'Orleans Rose' x Comtesse du Cayla' x R. foetida bicolor), an interesting amalgamation of Polyantha, China and Austrian Briar. It was raised by M.  Leenders &  Co of Tegelen, Holland,  and introduced in 1919 as `Mevrouw  Nathalie Nypels'.
