Founder and CEO of the "Laboratories of Doctor Debat" and creator of the "Doctor François Debat Prize".

It is said to be a really strong grower once pruned, which can be consistent with the habit and behavior of 'Radiance', but I do not know nothing apart from than that and I do not grow it neither, unfortunately! Regards ;)
Dr. Debat grows well on its own roots and has subtle, classic Tea coloring and Tea scent. My plant is less than 3 feet tall and is pruned rather hard. It seems to require such pruning to stimulate vigorous new growth.
