Has anyone had experience growing the Fragrant Tea Olive Tree (Osmanthus fragrans)? I'm thinking about adding it to my garden for its lovely scent, but I'm curious about a few things before I take the plunge. How well does it perform in different climates? I live in an area with a mix of hot summers and mild winters—would that be suitable? Also, how big do these trees get, and do they require a lot of maintenance? Any tips on soil, watering, or pruning would be greatly appreciated!
