Timing shifts with your zone — the Genie can pin down exact dates for you.
How to care for it
Plant plugs in spring 12-18 in apart in lean, gritty soil. Water sparingly — it resents wet feet. Light shear after flowering keeps it dense and releases fragrance underfoot.
Good companions
Sedum, lavender, roses, paths between raised beds as a pest-confusing edge
Harvest
Snip leafy sprigs anytime; flavor peaks just before the summer flowering.
