All rhizomes from ThymeGarden.com have been in the ground a coupla weeks and all have long since sprouted--some from maybe 2" and some up to 5-6"--Cascades, Centennial, Magnum, Hallertauer, Sterling--Last year's Chinook appear to be sprouting from the old wood just below the surface, small leaves less than 1"; last year's Nugget??? a little probing reveals shoots just below surface running horizontally.
Magnum sprouted first and growing best so far.
Here in Avon Park (adjacent to Sebring--about 60-70 miles south of Orlando near 27.)
