Several plants go by the common name "daisy tree." They are tropical plants that bear white or yellow flowers similar to a daisy, and have a pleasant odor. Some of the plants are actual trees, while others are shrubs that can fit on a patio or indoor greenroom. Varieties include the Montanoa hibiscifolia, which grows 20 feet high; the Podachaenium eminens, which is shrub-like and grows to 15 feet high; and the shrub-like Montanoa grandiflora at 15 feet high. USDA hardiness zones 10b through 11 are the recommended areas for planting.
Know specifically which species of daisy tree you are purchasing. Some plants require slightly different treatment than others. For instance, the Argyranthemum f. enjoys full sun but not high, direct summer heat.
Carefully choose a the location if planting outdoors. The daisy tree should receive full sun and protection from winter winds. Air temperatures under 20 degrees Fahrenheit will damage the plant and should be avoided. Careful nursing if it freezes might be able to bring the plant back to health depending upon the type.
Move a potted shrub around to take advantage of the best location. If grown in an area with a harsh winter, consider bringing it into the house for the season.
Prune the daisy tree after the peak flower season to keep it shapely. The tropical daisy tree requires a good amount of moisture and water but in the winter ease off from the water. If the plant is brought indoors during the winter, do not feed it until spring.
