Lemon Marigold, also known as Copper Canyon Daisy, is a small shrub that can be trimmed to a groundcover level. However, it has the potential to reach a few feet in height if left unchecked. This plant is known for its aromatic, airy foliage and vibrant yellow daisy-like blooms. Its finely divided foliage releases a strong fragrance when touched or brushed against.
The orange-yellow flowers of Lemon Marigold appear in the fall and winter, with off bloom in other seasons. The flowering of this plant is triggered by short day lengths, so overcast weather can extend the flowering period into the spring. It is best to plant Lemon Marigold in sun or part shade in well-drained soil. It is drought tolerant in coastal gardens, but looks best with a little irrigation. Too much water or too little light can lead to leggy plants that do not bloom well.
Lemon Marigold is a great choice for attracting butterflies to your garden. If you plan to keep this plant in a pot, it is important to use free-draining soil and water it frequently during the summer. In cold regions, a containerized Lemon Marigold can be overwintered by placing it in a protected position, such as a garage or greenhouse, during the harshest weather conditions. In USDA Zone 8-11, these plants can survive freezing temperatures as long as their roots are kept relatively dry and temperatures do not drop below 30 degrees Fahrenheit for an extended period. It is a good idea to provide a winter layer of mulch around the plant to keep the roots insulated and the soil moist.
