Greg, I see you are in WA. Have you ever been to Flower World in Maltby? It's not far from Woodinville. My sister worked there for years, and it's one of my favorite places to visit for plants.
I love your plant photos, Tarev. That is a nice Euphorbia Milii. I have one with small yellow/orange flowers and a larger Thai Hybrid with dark Orange flowers. Is yours a pink?
Audrey, just go for it. The plants with thorns require more care, but they're wonderful to own. I kick myself every time I want something and don't buy it. I go later, and it's always gone. Get it when you see it!!!
