Prefer on a boy:
Aspen Rowan ♥ - first association —
Rowan Atkinson.
I'd use
Rowena or
Ravenna for a girl.
Hawthorn
Forest - my least favourite in this category. It's just too blunt.
Ash
Prefer on a girl:
SageEmber - I think it's a cute NN for November, my GP.
Briar ♥ - I like how this prickly sweet thing looks and sounds. One of two B names on my PNL.
Winter - I prefer
Summer or
Autumn.
Sky Juniper
Rain - on the one hand, it's close to girl names
Raina,
Raine,
Renée,
on the other, there is a masculine
Rein.
But I still prefer it on a girl, I guess.
And
Indigo is unisex.
Indigo powder, indigo colour and indigo kids come to mind. It also reminds me of
Inigo (
Inigo Jones).
