Upright Rosemary
Needle-like leaves with dense revolute margins and pale undersides. Best harvested at mid-morning when resin oils peak before midday heat, cutting only green non-woody branch tips.
Narrow-Leaved Thyme
Tiny ovate leaves on wiry square stems that thrive in dry gravelly soil. Clip the upper third before violet flowering begins to maintain pungent thymol balance in stocks and roasted roots.
Pointed Garden Mint
Opposite serrated foliage with vigorous underground runners that benefit from container containment. Harvest entire leafy stems above leaf nodes to stimulate immediate secondary bush growth.
Bronze Fennel
Delicate feathery frills yielding sweet anise aromatics and ribbed seed umbels. Snip tender young foliage for broths or harvest mature green umbels when autumn moisture recedes.
Temperature and extraction chemistry
Non-woody cold extraction
Sub-boiling steepings
Lignified stem decoctions
Aerated ambient drying
Submerge crushed tender leaves of mint or lemon balm in filtered cellar-temperature water for twelve hours to extract volatile aromatics without bitter tannins.
Pour eighty-five degree water over fragile florets and leaves in covered porcelain, preserving heat-sensitive terpenes from evaporating into steam.
Simmer woody roots and thick rosemary twigs on low flame for twenty minutes, breaking through dense cellular walls to release mineral compounds.
Suspend loose bundles downward in shaded thirty-percent humidity corridors, avoiding direct solar ultraviolet rays that bleach chlorophyll.
