exceptionnally nice, I'd say. Many of them turn out so droopy & bedraggled you want to put them out of their misery. Very nice form and colour. I think mine may be about to bloom--I devoutly hope it will be as elegant as yours.
Happy growing

to add that the Frenchman in me is delighted by the proper spelling of Ma Belle ("belle" is here a feminine noun, the possessive must be in the feminine as well). "Ma Bell" is a monster and meaningless in all known languages, unless you refer to the Bell company as in Ma IBM (!!!!).
Yours
