Searching for source for a Knaphill-Exbury Hybrid called 'Topaz." First purchased at Carlson's Gardens many years ago.
I was having trouble finding any record of a deciduous azalea named "Topaz".
Searching various catalogs, I found:
"Gold Topaz", an Exbury azalea from Glendoick Nursery in Scotland.
Looking in Ken Cox's book "Rhododendrons & Azaleas, A Colour Guide" there is a listing:
"Goldtopas, Orange-yellow, strongly blotched orange. Dark-green foliage is reddish brown on the young growth, probably the best of any Exbury hybrid. One of the most impressive yellow-hybrids, but we don't find it all that easy to propagate. Hachmann"
Looking for "Goldtopas" there is a photo at:
where it describes "Goldtopas" as:
Knap Hill azalea 'Goldtopas'
Parentage: ('Cecile' x 'Klondyke') x 'Marion Merriman', Hachmann, 1983.
Habit: Compact wide habit. Height 1 m in ten years.
Flowers: Vivid yellow to light orange yellow with a strong orange blotch. Flower size 6.5 to 7.5 cm.
Cold Hardiness: -15Â°F, -26Â°C.
Having gone through this, Glendoick in Scotland and Hachmann in Germany are the only sources I can find and that is for "Goldtopas". I don't have the slightest idea how to get one to Tennessee.

Thanks for your reply. The 'Goldtopas' picture is not like the bloom on my 'Topaz,' and the new foliage doesn't have the leaf coloration described. My topaz has bright, pure orange-yellow blooms. Alas, because of the drought here in the Southeast over the past three years, it did not set bud and will not bloom this year.
I found 'Topaz' listed at the site below, but no info on any source. I have emailed Carlson's Gardens to see if they have any that are not listed on their site.
The 'Goldtopas' is lovely - I may have to obsess over it if I can't find my Topaz.
