I had 4 plants near my front door. One of them died and I was trying to replace it. I bought a lavender from Home Depot and it was totally different as you can see (the small one in the middle of my larger ones(around 2 feet high 3 feet wide)). Can you help me identify what my plant is? What type? Where to buy it from? Any other suggestions (alternatives that will be about similar size and looks nice with mine)? Thank you in advance. I live in Phoenix (can get real hot) and this will receive the afternoon son.
