Titan Sunflower is recommended for the following landscape applications;

  • Accent
  • Mass Planting

Planting & Growing

Titan Sunflower will grow to be about 12 feet tall at maturity, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 24 inches apart. The flower stalks can be weak and so it may require staking in exposed sites or excessively rich soils. This fast-growing annual will normally live for one full growing season, needing replacement the following year.

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It may require supplemental watering during periods of drought or extended heat. This plant is a heavy feeder that requires frequent fertilizing throughout the growing season to perform at its best. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selection of a native North American species, and it is considered by many to be an heirloom variety.; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
