Lemon Marigold- Tagetes lemonii is fast growing to 6 ft. And comes from Mexico. It blooms when not a lot else is in SoCal; winter to spring. I took this photo right before I whacked it in half at a client's house. It has a Lemon/herb-y fragrance. With my allergies, it really makes me sneeze to trim it. It also has pointy pokey little seeds that get in ones clothes after pruning. It may seem that I dislike this plant for all it does to me. But I still love it for it's bright show of color, fragrance and fast growth in full sun. Found in most nurseries.
