Mexican Shellflowers Mixture
Mexican Shellflowers, also known as Tiger Flowers, are in the Iris family and are native to Central and South America. Each flower lasts only a day, but a succession of blooms will provide a show for several weeks. Our mixture contains plants that will bloom in shades of pinks and red to white, cream and yellow.
Plant after the soil has warmed and night temperatures remain above 55°F. Mexican shellflowers do best in full sun with fertile, moist, well-drained soil. Plant 3-4” deep and 4-6” apart, with the tapered end up. Water well. If desired, plant in succession every couple of weeks to extend the blooming season. Mexican shellflowers may also be planted in a container with drainage holes and good quality planting soil.
Feed with a well-balanced fertilizer in the spring. Stake if needed. Feed container grown plants every couple weeks.
Mexican shellflowers are only hardy in USDA zones 7-10. They are usually treated as annuals in colder climes, but may be dug up and stored for the following year. After the first frost, dig the bulbs and allow them to dry completely in a frost-free location. Once dry, remove the foliage and excess soil. Store them in dry sand or peat moss in a cool place, 40-50°F.
