"Adam" one of the first Tea roses bred in the West and to my eyes one of the finest. It is usually grown as a short climber, of c. 8 feet tall, and is more tolerant to cold than most Tea roses, because it has one Bourbon rose parent. Still in its exquisite bloom style and frequency it appears all Tea. It has a lovely hues of amber and apricot in its heart, with deep rose to light rose pink, more pink in some weather, more apricot- amber in others. "Adam" is more fragrant than most Tea roses from his Bourbon parent, I deem.
Luxrosa.

For longest bloom period in a cool climate, I would choose "Crepescule" and "Lamarque" both are healthy and are grown without spray where I live near San Francisco, California. "Lamarque is far more resistant to powdery mildew than Mme . Alfred Carriere" in our garden. Though called Noisettes, their blooms have all the delicacy of a Tea rose.

I love "Crepescule"s' twilight hues of rich flaming orange and it has attractive deep green foliage. I do not love "Lady Hillingdon" as much as I think I ought.

If you deadhead promptly the roses listed above will bloom pretty much continuously. "Adam" gives 2-3 to 4 bloom cycles per year in a cool climate.

Suzy, I have always longed for one of those beautiful glasshouses in the back of the gardening magazines, but having no real estate, no money and ample sun already, it's a wasted dream, I guess. When you mentioned growing Marechal Niel in a greenhouse, I almost choked, but I suppose he wouldn't be the house-eater there that he is reported to be here. But still, I have this picture in my mind of your cheek and nose pressed firmly against the glass of your glass house and MN pushing ferociously against your back, filling the whole volume of that 10'x12'. Eww, don't ask about all the blood I see dripping down the glass. Marechal Niel is definitely gorgeous, and I can see why you would want to give him a try, especially since I adore yellow roses. It will be a wonderful experiment right up until he...

P.S. Just think how your cooler temps will deepen all the pastels of the teas. Lovely. I think you should pick the ones your heart falls in love with and go for it, including at least one bush. After all, it should stay a rather petite size, no?

Ha, Sherry, fell about laughing, not least at the mention of 'beautiful glasshouses'. Mine is a bit more 'industrial' in that stuff like red cedar or finials are miles away from the dull steel and glass monstrosity I actually possess. Marechal Niel - I had no idea. Well, I have no idea about most teas since until getting involved with you lot, they were in the realm of other such fantasies as mangos, avocados, baobabs, frangipani etc. Since the garden in its entirety involves sucking in your breath to get from A to B, I will probably pass on another giant.
Adam, however sounds good especially since I do grow bourbons (ahem, 2) and feel confident, if their growth patterns are sinilar, that I could contain this rose in a mannerly fashion against the same side of the glasshouse as the plumbago. My only reservations concern the colour mix - pale icy plumbago blue with apricot/pink rose. Well worth a punt though since they will be in huge pots as I have a solid foundation under the greenhouse with no soil borders (no soil exists in my garden that has not been trundled there by me, anyway). Still lots of time to do another order!
