An oddity?

Last year I ordered Maggie (my "red" rose which turned out flaming magenta; my pink-hating wife hasn't forgiven me), and she's blooming her little head off now.

But her calyxes, which at first glance I thought were encrusted with tiny aphids, turn out to be- mossed. Green, velourish growth which when rubbed gives off a very pungent balsam scent.

Is this normal for Maggie? Do I have a sport? I note that on rosegathering.com Maggie is described as 'sometimes' having a balsam-toned fragrance; other sources call her fragrance "peppery" although to my nose the bloom itself is all damask-y Old Rose.
