Dwarf Lemon Cosmos Seeds

Key Features

• FAST BLOOMS IN 50–60 DAYS, GERMINATES IN 7–21 DAYS — These Dwarf Lemon Cosmos seeds sprout in just 7–21 days at 65–75°F (18–24°C) with reliable germination. Direct sow after last frost in full sun, and expect bright lemon-yellow blooms within 50–60 days — one of the fastest cosmos varieties for warm-season color.
• COMPACT PLANT HABIT – 12–24" TALL & WIDE — Dwarf Cosmos sulphureus grows into a tidy, branching plant 12–24 inches tall with a 12–24 inch spread. No staking needed. Space plants 9–12 inches apart for dense, bushy growth in borders, edging, and mass plantings without overcrowding.
• PERFECT FOR CONTAINERS – KNOW YOUR SIZE — For container gardening, use pots at least 8–10 inches deep and 10–12 inches wide per plant. These compact cosmos thrive in balcony planters, patio pots, and window boxes, producing continuous 2–3 inch lemon-yellow blooms from summer through frost.
• POLLINATOR FRIENDLY – ATTRACTS BEES & BUTTERFLIES — Bright yellow blooms from Cosmos sulphureus 'Dwarf Lemon' draw bees, butterflies, and beneficial insects throughout the growing season. A natural fit for pollinator gardens, wildlife habitats, and mixed border plantings across USDA Zones 2–11.
• HEAT & DROUGHT TOLERANT ONCE ESTABLISHED — These cosmos seeds thrive in full sun and warm conditions (growing best at 65–85°F / 18–29°C). Drought tolerant once established, they perform well in low-fertility soils, xeriscapes, and low-maintenance beds — minimal watering needed after the first few weeks.
• SOFT LEMON-YELLOW COLOR – NATURAL VARIATION EXPECTED — Blooms are consistently soft lemon-yellow, with 2–3 inch single flowers that add a delicate, cheerful tone to any garden. As with all open-pollinated varieties, 5–10% of plants may show deeper golden-yellow or cream-toned shades — natural variation, not a defect.
• 2 PACKS, 300 SEEDS EACH – OPEN-POLLINATED & NON-GMO — Each order includes 2 seed envelopes (2.2g each / 300 seeds per pack), covering approximately 15.5 sq. ft. per envelope. Open-pollinated Cosmos sulphureus seeds produce true-to-type plants — save seeds each season to replant year after year.
