Start seeds indoors or outside greenhouse. For best chances of germination use a heat mat or warm location inside the house. Keep the soil temperature for most perennials at 70-80 degrees F. Place plants in a sunny location such as a South facing window or greenhouse. Artificial light works as well.
Obedient plants are easily established and very drought tolerant, forgiving plants. Although they prefer a moist, slightly acidic soil (5.5 - 6.3 pH), they’ll grow just fine in average - poor soil and spreading will be less of a problem. Transplant outdoors before the last frost or at the beginning of autumn. Spacing 12 to 24 inches

Don’t fertilizer your obedient plants, unless they show signs of nutrient deficiencies.
The biggest maintenance chore is keeping obedient plant from rampant spreading. Although the plants pull out easily enough, they seem to pop up everywhere. If you’re tempted to wait and let them flower, be sure to get out there before they go to seed.

Long season gardeners can get a second flush of blooms if you deadhead the first flowers. This will also cut down on the self-seeding.

Wait until spring to cut back old foliage. Leave it on the plants to act as a protective winter mulch.
 Cut to ground after bloom; divide every two years to keep plants in bounds.
​​Allow seedheads to dry on plants; remove and collect seeds.
