Beat me to it, I was going to mention Joe's Regal Star.
Here it is, a mountain of a lily dwarfing all other OTs at the 2015 Claremont Show:
Yep, to best of my knowledge it is Tetra Black Beauty x Tall Boy. An incredibly vigourous plant. In this case it would hold with Dr. Griesbach's advice, to keep the O and T percentages close; O-T x O-T. T being henryi in both cases.
I wanted to expand on the 'O' part of TallBoy (it being L. henryi x 'Valley Sundust') and looked up the registry to get my facts straight. Here's the details of 'Valley Sundust':
L× parkmanii ‘Valley Sundust’ VII(b-c/b)
Parentage:
L. × parkmanii ‘Jillian Wallace’ X auratum var. platyphyllum

20 fls. Jan. (Australia)
'Jillian Wallace', in turn, was:
L. × parkmanii ‘Jillian Wallace’ VII(b/c)

the raiser’s first grandchild.)
And Crimson Queen:
‘Crimson Queen’ VII(b/b)
Parentage: reputed to be
auratum var. platyphyllum × speciosum ‘Melpomene’,
but thought by some to be a form of auratum
R: unknown
Each tepal with a wide crimson ray. Fls
auratum type. Stems 1.2 m. Aug.
Syn.:
auratum ‘Crimson Queen’.
(Published in Wallace Cat.1902: 9.)
Whilst searching I happened across two more Tall Boy offspring Joe raised and registered! Shamefully for a Vandemonian, I've never heard of either, but I shall attempt to find out if they are still grown by anyone!
‘Valley Boy’ VII(-/-)
Parentage: L. × parkmanii ‘Valley Sundust’ X ‘Tall Boy’
R: J. Hoell (1982), G: J. Hoell (1986), N: J. Hoell
(1991), I: J. Hoell (1991), REG: J. Hoell (1991)
Inside white, with light orange-yellow (16B) rays, throat
light yellowish pink (36C); outside strong purplish pink
(55B); spots brown on two-thirds of each tepal; nectaries
green; pollen strong red (46A). Fls 160 mm wide; tepals
110 × 50 mm, margins smooth, tips strongly recurved.
Lvs scattered, 130 × 35 mm, mid green. Stems 1.65 m,
moderate olive-green (137A). Jan. (Australia).
'Valley Dawn’ VII(-/-)
Parentage:
L. × parkmanii ‘Valley Sundust’ X ‘Tall Boy’
R: J. Hoell (1982), G: J. Hoell (1986), N: J. Hoell
(1991), I: J. Hoell (1991), REG: J. Hoell (1991)
Inside white, each tepal with a brilliant yellow (12B)
ray, throat pale purplish pink (56C); outside moderate
purplish red (186A); spots moderate purplish red (186B)
on two-thirds of each tepal; nectaries brilliant yellow-
green (142B); pollen moderate reddish brown (166B).
Fls 192 mm wide; tepals 155 × 55 mm, margins smooth,
tips slightly recurved. Lvs scattered, 190 × 50 mm, dark
green. Stems 1.7 m, moderate yellow-green (138B), with
18-20 fls. Fertile. Feb. (Australia).
It's curious that Joe registered them as Div VII, though reportedly Tall Boy itself was first registered as Div VII also. Maybe this was pre-Div. VIII days. I think I remember those.
Anyway, they are both backcrosses, so for those of us attempting to use Tall Boy it's interesting that the pollen was successful onto oriental division. I've mostly tried the other direction. When I was given Tall Boy I was told that it was more fertile as the pollen parent but I haven't has any success in that direction yet. Pods sometimes form, but with iffy looking seed and no germination. Must be doing something wrong.
Here's another of Joe's Tall Boy babies, 'Golden Beauty':
‘Golden Beauty’ VIII(c/b)
Parentage: ‘Tall Boy’ X ‘Tetra White Henry’
R: J. Hoell (1988), G: J. Hoell (1992), N: J. Hoell
(1994), I: J. Hoell (1995), REG: J. Hoell (1994)
Inside vivid orange-yellow (23A) throughout; outside
vivid orange (28B) on inner tepals, suffused with strong
reddish orange (32B) on outer tepals; spots absent;
papillae self-coloured; nectaries vivid yellowish green
(140A); pollen vivid reddish orange (30A); style and
stigma dark-coloured, stigma 3-lobed with a distinct
central depression. Fls 170 mm wide; tepals 105 × 48
mm, margins smooth, tips becoming strongly recurved;
pedicels heavily spotted vivid violet (89B). Lvs scattered,
245 × 42 mm, dark green. Stems 1.65 m, heavily spotted
vivid violet (89B), with up to 30 or more fls of very heavy
texture. Mid to late Dec. (Australia).
I haven't grown it but I'm often told it was one of Joe's best breeders; a parent of some of his best lilies. It is still grown, well-loved and used among the lily breeders down here.
Yes, oodles of potential in old Tall Boy. Can't wait for next summer now!!!
