The tag says full sun. It doesn't say which sun. ☀️
Eight hours against a south-facing brick wall is not the same as eight hours in an east-facing bed that loses direct light by 2pm. Same count on paper. Completely different heat load. The herb that bolted wasn't in too little light — it was in too much of the wrong kind.
South-facing — full hot sun: rosemary, thyme, oregano, lavender, and sage. Mediterranean herbs increase essential oil production under heat stress. More sun, more heat, more flavor. These want the hot wall.
East-facing — morning sun, afternoon shade: basil, cilantro, and dill. Basil bolts weeks faster under sustained afternoon heat. An east-facing position extends the harvest by 3 to 4 weeks over full south exposure. Cilantro is more extreme — two weeks of hot afternoon sun and it goes to seed. Morning sun and dappled afternoon shade keeps it productive.
North-facing — 4 to 6 hours indirect: mint, parsley, and chives. The shaded side of the house, the spot behind the garage, the porch that gets morning light only. Mint actually produces more menthol under reduced afternoon sun. These three thrive where sun-lovers starve.
West-facing — afternoon blast, morning shade: the wrong side for most herbs. Harsh afternoon heat burns leaf edges on everything except the Mediterranean group, and even they prefer south over west. 🌿
Match the herb to the exposure you actually have. The rest follows. 🌱
