Interested to see who got the reader's choice for this. Here's my vote if it matters. I've been very successful everytime I visit Pahl's Market in Apple Valley. They have a wide selection of flowers and plants that i use on my landscaping projects, and they help me chose the ones that will survive in my yard, because dead plants really ruin the look of my yard hahah. They have plenty of work shops and fun events which I can bring my family and friends to as well!
