Like other vincas, Stardust Orchid is heat and drought tolerant. Plants perform best in well-drained soils and full sun. They perform poorly in wet soils and cool weather. The shorter plant height discourages breakage and makes it easier to use the plants in the garden. The large leaves have a velvety texture.
Mexican sunflowers are heat and drought tolerant.
They perform best in well-drained soils and full sun. Avoid wet, poorly drained sites. Fiesta del Sol begins to bloom about 12 to 15 weeks after the seeds have been sown. To promote early bloom, buy transplants at a garden center or sow seeds indoors about 6 weeks before the intended outdoor planting date. Since the tithonia prefers warm temperatures, do not transplant outdoors until mid to late May in Iowa.
