The first dwarf Mexican sunflower, 'Fiesta Del Sol' thrives on summer heat and humidity attaining a mature height of 2-3 feet. The single, orange daisy flowers are 2-3 inches across, excellent cut flowers and may attract butterflies. There are an abundance of daisy flowers so that you can cut many for informal bouquets and numerous flowers will remain on the plant for the wildlife.
Basically pest free, not even deer find the hairy leaves of Tithonia rotundifolia worth eating. Easy-to-grow from seed or plants, 'Fiesta Del Sol' is carefree in the garden or in patio containers with a six inch or larger diameter.
The pumpkin orange daisy flowers combine well in the garden with dark blue Salvia farinacea spikes or primrose marigolds. The lush plants need only fertile soil and watering to achieve maximum performance in full sun. Sensitive to cool temperatures, wait until warmer weather for transplanting.
