How To Plant
Propagate by seed
Plant seeds outdoors where desired after the danger of frost has passed, or
start them indoors 4 weeks before the last frost date. Indoor sowing is not recommended,
as Nasturtiums do not transplant well. The seeds need darkness to germinate.

Maintenance and Care
Train vining varieties onto supports.
Look for varieties with different flower colors/striping/mottling, various foliage colors, and vining or mound-forming shapes.
- ‘Whirybird’ series: 1 inch tall bushy plants with semi-double flowers in shades of pink, yellow, red and orange. flowers do not have the typical nasturtium spur which forces them to rest at angles on their stem. flowers sit flat on stem tops and are ruffled and showy.
- ‘Alaska’ series: 1 inch tall plants with green leaves mottled with white/cream.
- ‘Tom thumb mixed’: dwarf variety (8 to 10” tall) with bright yellow, red and orange flowers on compact, mounded plants.
