After my firecrackers were in ground for about 2 weeks, the plants started turning brown. Can someone please tell why this would happen and what I should do to fix it, if possible. Thanks.

It makes a great border plant. It spreads by its root system and stems will take root if they touch the ground. Full sun to partial sun is best for good blooming.
