Zinnia ‘Isabellina’ has 4-5 inch wide flowers that are light yellow. This species is native to Mexico, and plants are fast-growing and long-blooming. Zinnias make good cut flowers. In addition, they are excellent for pollinator plantings and are especially attractive to butterflies. Direct sow in spring; this seed germinates best in warm soil. Plant just below the surface and keep the soil lightly moist until germination, which usually occurs within 7-10 days. Seedlings do not transplant well. Water seedlings regularly until they become established, but do not over water. Though they flourish with occasional watering in dry weather, mature plants tolerate some drought. This plant grows best in rich soil, and may need light fertilization for best blooming. Pinch off the growing stems to encourage bushiness, and deadhead to prolong blooming. This plant attracts butterflies and bees.
