Mexican Sunflower Orange (Tithonia Speciosa Goldfinger) - Mexican Sunflower Goldfinger can be easily grown from Tithonia seeds. The incredible 3 - 4 inch orange flowers are excellent for cutting. They also are butterfly magnets, particularly the Monarch butterfly. The plants begin blooming in July or August and continues until frost. Grow these flowers behind beds or borders where their coarse texture, rangy habit and vivid flowers will stand above less boisterous plantings. Orange Tithonia plants may grow as a perennial in USDA Zones 10 - 11.
Growing Mexican Sunflower from flower seeds is extremely easy. Directly sow the seeds into prepared seed beds after all danger of frost has passed. Amend the soil with organic compost a couple of weeks before sowing the Tithonia seeds. Sow the flower seed in groups of 2 - 3 seeds spaced 12 - 18 inches apart. Thin to the strongest plant. The Orange Mexican Sunflower plant will benefit from having the spent blooms removed. The plant thrives in hot, sunny climates and does best if it is allowed to dry out in-between deep waterings.
