You can however, decide to cut the flowers before they turn brown, and bring them inside to use as a centerpiece. They will not last as long cut though as they do in the ground.
If you have decided to give these flowers a chance, and grow them in your garden, here is what you need to do.
We already discussed where to plant them on how the temperature is in you town, state, or country.
The next thing to do is to make sure you have an area where the soil is moist. Dig a hole about 4 inches deep. Put the plant in the hole, and then throw in some mulch almost up to the top. Leave a little bit of room and surround the plant with the soil.
Since this is a perennial plant, it will grow each year. Fertilize the plant each spring to promote wonderful growth.
You do not need to water this plant daily. Water it so much that the soil looks very wet and dark. Let it dry up before you water it again. Then repeat each time it needs watering.
This is a very low maintenance plant. Enjoy this plant in the summer months, and throughout the year!
