My top association is the plant/flower Angelica. The delicate bunches of white flowers remind me of Baby's Breath and in some places it is regarded as an herb.
It does come across as a bit too precious, but I don't dislike it. The hard 'c' gives it a bit more oomph compared to other angel names, which can come across as brassy. While Angelina reminds me of a ballerina, Angelica seems more like a headstrong force of nature.
