How to grow it

Things you need:

Bypass Pruners

Compost Makers


Garden Hoses

Garden Spades

Garden Stakes



Step 1 Choose a site with average to poor, well-drained soil in full sun.

Step 2 Plant seeds directly in soil after your region’s last average frost date. Or start seeds indoors six to eight weeks earlier.

Step 3 Thin plants to about 2 feet apart.

Step 4 Keep soil evenly moist, but don’t overwater – this flower likes it a little on the dry side.

Step 5 Trim faded flowers to promote longer blooming.

Step 6 Fertilize every 8 to 10 weeks, or work in a slow-release fertilizer (or plenty of compost) at planting time.

Step 7 Tear out and discard plants in fall, after frost fells them.
