One of the things I adore about thyme is that it works beautifully both in containers and spread amongst the other plants in the garden, potager-style. It adds a nice splotch of green, and when it does blossom, the little mason bees adore it! I've got a bunch of varieties of both culinary and ornamental thyme growing throughout our front & back yard gardens, and the bonus? I never have to worry about running out!
Two tips: 1) Once it finishes flowering and the tips dry out, make sure to deadhead them, which will ensure it doesn't get too leggy and more greenery returns; 2) Make sure before the season is over to harvest a whole bunch extra and dry it for winter use in the kitchen!
