This nasturtium reaches full maturity at a tidy 10 to 12 inches, making it perfect for edging beds, containers, and smaller garden spaces where taller varieties might overwhelm. The blend of warm Fiesta colors combined with its compact habit gives you ornamental impact without sprawl. Fiesta Blend germinates reliably between 55 and 65 degrees Fahrenheit, and the plants tolerate the full sun to partial shade spectrum, adapting well to varied garden conditions. Direct sowing after your last frost date is the recommended approach, sidestepping the root disturbance issues that indoor starting can cause with this sensitive species.
Nasturtiums in the Fiesta Blend are primarily grown as ornamental flowers, prized for their warm, cheerful blooms that add visual interest to garden beds and container arrangements. The compact 10 to 12 inch stature makes them especially valuable as edging plants or focal points in small spaces.

Starting nasturtiums indoors is not recommended due to their sensitive roots, which are easily disturbed during transplanting. If you choose to start them indoors despite this, sow 2 to 4 weeks before your average last frost date at a soil temperature of 55 to 65 degrees Fahrenheit, and use biodegradable pots that can be planted directly into the ground to minimize root disturbance.
Transplant seedlings outdoors after your average last frost date, spacing plants 8 to 12 inches apart. Since direct sowing is the recommended method, most gardeners skip indoor starting altogether and sow directly in the garden.
Sow seeds directly outdoors 1 to 2 weeks after your average last frost date, which is the recommended planting method. In mild climates, you can sow in fall for winter bloom. Plant seeds at a depth of 1/2 to 1 inch. When seedlings reach 2 inches tall, thin them to one plant every 8 to 12 inches.
