@gracehong I have these growing in a planter next to my house. They are annuals, but mine come back every year. Mine are purple. They come back bc they are so close to the house, I think. They get bigger and thicker every year. I even think I need to thin them out.
@camilio81 Wow!! That must be quite a sight. My mom has a small bunch of them that would be doing better I think if they weren't getting crowded out by her giant impatiens 😆 Sounds like yours are doing very well 😍
