Princesse de Nassau ('Autumnalis') Noisette. Laffay (France) 1835. Description... This rose is more generally known as 'Autumnalis' and is a form of the Musk Rose related to 'Blush Noisette'. Graham Thomas has equated it with Laffay's 'Princesse de Nassau'... sprays of small, creamy yellowish, double flowers, nicely scented in the musk way...

R. moschata 'Autumnalis'                   before 1912
syn: 'Princesse de Nassau'
'A pretty plant, with a few hooked thorns; light yellowish green leaves, limp and matt, and does not flower until August ... Dainty sprays of small sme-double blossoms on softly downy stalks; silky petals, deep cream buff on opening ... fading cream, with yellow stamens and a delicious fragrance.'

In 1983 Graham Thomas reported this rose: 'I include this rose', he wrote, 'with some hesitation, since I cannot vouch for the name; it is not in any book I have consulted, but occurs in a Daisy Hill Nursery catalogue dated 1911.'
Later he added that he thought it may be 'Princesse de Nassau', and in the most recent edition of his monographs on roses he has abandoned Thomas Smith's name in favour of 'Princesse de Nassau'. Thomas Smith, in fact, listed 'Princesse de Nassau' in several catalogues, ant it was G. N. Smith who seems to have introduced the name R. moschata autumnalis (Newry roses no. 138: 13 [1935]), when he described the rose as 'a form of Musk rose which flowers in the Autumn, large trusses of fragrant flowers in October'. I think there may have been some confusion in the nursery over these roses.

Princesse de Nassau This came to me ...labeled Rosa moschata 'Autumnalis'...a name...not in any book that I have consulted....hooked prickles...light yellowish green leaves limp and matt, and does not flower until August, carrying on until the autumn....Dainty sprays of small semi-double blossoms on softly downy stalks; silky petals, deep creamy buff on opening from pink-tinted yellowish buds, fading to cream with yellow stamens and a delicious fragrance.... thornless branchlets proceed in zigzag fashion from leaf to leaf. Possibly a Noisette of very early origin, such as 'Muscate Perpetualle'....

Princess of Nassau Probably early 19th century.  A recent  rediscovery, I believe by Graham Thomas, who sent me budwood in 1982.  These flowered as maiden plants, coinciding with R. moschata and going on well into autumn, fitting Paul’s descriptions almost perfectly.  Flowers, yellowish-straw, form-cupped, very sweet.  I add to this, light green foliage.  I can now vouch for its hardiness since it survived the severe winter of 1984/85 with only moderate frost damage.  Quite vigorous.  (R) (P) Shade tolerant, (MF) (AL) 10 x 8’.  3 x 2.5m.

Autumnalis R. moschata ‘Autumnalis’.  Probably R. moschata x R. chinensis.   An interesting rose.  The rose I describe is the variety I have grown under this name for many years but I have never been quite sure if it correct.  It is a small climber similar to Princess of Nassau’ except more vigorous.  Large clusters of semi-double cupped flowers of creamy-white to pure white produced, it seems, with some reluctance from August through to early winter.  Slightly scented.  Foliage light green. Stems, almost thornless, also light green.  Probably better in warmer climates than Norfolk. (C)  (T) (N) Shade tolerant. (SF) (AL)  10 x 6’.  3 x 1.m.
