Growing Under the Sea Mix Zinnia

‘Under the Sea Mix’ is a colorful zinnia blend prized for its tropical-inspired palette, large dahlia-style blooms, and abundant summer flowering. Flowers appear in rich shades of coral, deep violet, and sandy white, creating a lush, exotic-looking display in beds, borders, and containers.

Start ‘Under the Sea Mix’ indoors for transplanting or sow directly where conditions allow. Plant seeds about ¼ inch deep and space plants 12 to 18 inches apart. Grow in full sun. This heat-tolerant variety is well suited to containers.

Ready to bloom in about 70 days, enjoy the flowers as they open and reach their best display stage. Long-lasting blooms provide excellent stems for fresh arrangements while attracting visiting pollinators.

Bold, colorful, and heat tolerant, ‘Under the Sea Mix’ is an excellent choice for beds, borders, containers, mass plantings, cut flower gardens, and pollinator-friendly plantings.

Can't wait til Spring

Too cold in North Dakota to plant zinnias but will as soon as the snow melts and it gets warm. Love the fact that there are 100 seeds in a packet!! Check back with me in the Fall.
