I bought a plant about 30 years ago that I grew in a hanging basket and I just stuck in the garden when it was fading. I have no idea why. It was supposed to be an annual, but it is still growing every year. I took several cuttings in the fall and that is the plant we are planting. All we needed was a lovely hosta to finish off the garden. Mission accomplished. My choice was Winter Snow. Right size, right colour. It will be lovely. For now it is tiny, about 8" tall. can you even see it??
