Mrs Herbert Stevens HT. rrrr / fff / 3.  McGredy 1910 [Robinson].
Long pointed pure white buds unfurl with all the grace of a Tea rose.  The plant would assort well in a garden of Teas, for its bushy floriferous habit and nodding flowers give it that look.

3rd Nat Conference, Fremantle Proceedings.
p62-63. David Ruston: And this of course is 'Mrs. Herbert Stevens'. All the authorities says she is now a Hybrid Tea, but she looks exactly like the old 'Niphetos', which means snowy. A lovely rose both in the climber and the bush. And when we were at a previous Tea Rose Symposium I said one of the characteristics of the Tea is that you can get four or five shoots from one eye. I call it the pincushion effect....If you look at....'Mrs. Herbert Stevens'.....instead of having one shoot from an eye, they have five or six.

Hahndorf Conference. Walter Duncan. Teas and Noisettes.
p58. Mrs. Herbert Stevens (1910) is a lovely white Tea; a huge bush about two metres high. With its nodding heads, it is a graceful plant in every sense of the word. There is not much light green foliage at the base of the plant, so it is probably best kept at the back of the bed. There is also a true climbing form of this rose. As Maureen explained yesterday, it is a true climber rather than a mutated climber. it does not repeat-bloom.

'Niphetos'. There are two forms of this rose, a bush form which appeared in 1843 and the climbing form which was first propagated in 1889. It has charming creamy buds opening to pure white with pointed petals, which highlight a muddled centre.

p62. David Ruston: Is there any difference between ‘Niphetos’ and Mrs Herbert Stevens? You have got me a bit worried. I know that ‘Mrs Herbert Stevens’ is a seedling of ‘Niphetos’ and I have them together and I cannot tell the difference. I am wondering whether, when I imported ‘Niphetos’, it wasn’t ‘Mrs Herbert Stevens’ that I imported.
Walter Duncan: To be quite honest I do not know. The plants I grew years ago of ‘Mrs Herbert Stevens’ I know well. ‘Niphetos’ I don’t know well enough to define. Does anybody know the answer to that? My plants of 'Mrs Herbert Stevens' were about one and a half metres high. The wood was red. They definitely hung their head. The flowers formed in fives with very light yellow-green leaves. In general, I don’t know but it could be the case that they are still the same here.
David Ruston: I asked in France and Europe about ‘Niphetos’ and they all looked at me and said that a couple of years ago they had a very cold winter and all the plants died.
