A candle for open air — citronella-adjacent, never citronella.
The room
The porch wants open air and a candle that holds its own outside — grassy, citronella-adjacent, never actually citronella.
What to burn
scent vetiver, or cedar level two candles, out of the wind when evening, dusk avoid anything delicate
The point
Wind moves scent. Burn two small candles instead of one big one, and the whole porch gets the throw.
