White Globe Amaranth is a frost-tender heirloom flower that produces distinctive papery white blooms from summer through fall, reaching 24-30 inches tall in full sun. Native to warm climates (zones 10-11), this drought-tolerant member of the Amaranthaceae family germinates in 14-21 days and blooms 84-112 days after sowing, making it a reliable choice for late-season color. Its compact form and low water needs suit containers, borders, and cutting gardens alike.

Those crisp white globe-shaped flowers feel almost delicate but prove remarkably durable, lasting weeks in the garden and holding their shape beautifully in dried arrangements. This heirloom thrives on neglect once established, needing little water and asking only for full sun and warm soil. Bees and butterflies visit consistently throughout the long bloom window, turning your garden into a pollinator haven from June straight through November.
White Globe Amaranth shines as a cutting flower, with blooms that last exceptionally well in the vase and dry beautifully for arrangements that hold their color and form for months. Gardeners grow it to attract pollinators and add textural interest to borders, where the spherical white flowers contrast elegantly with darker foliage plants.
No timeline data available yet for this variety.
Start seeds indoors 6-8 weeks before your last frost date. Soak seeds in hot water for 4 hours to speed germination, then sow in sterile seed-starting mix at a depth of 1/4 inch. Keep soil at 70-75°F; germination takes 14-21 days. Seedlings are ready to transplant once they develop true leaves.
Transplant seedlings outdoors after the last frost date when soil has warmed. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before planting. Space plants appropriately for your layout (the data indicates 1-inch spacing for direct seeding, though container and bed spacing may differ based on mature width of 18 inches).
Direct sow seeds outdoors after the last frost date once soil has warmed to at least 70°F. Sow at 1/4 inch depth and keep soil consistently moist until seedlings emerge in 14-21 days. Thin seedlings as needed once they develop true leaves.
Cut flower stems for arrangements once the white globe blooms have fully formed and papery texture is evident, typically in mid to late summer through fall. Harvest in the morning for longest vase life. For drying, cut stems when blooms are fully mature and dry them in bundles hung upside down in a warm, airy location.
