Signet Marigold - Red Gem - Tagetes tenuifolia - Elegant colour for refined border display - Fresh Seeds

Signet marigold Red Gem (Tagetes tenuifolia) is a delightful annual that brings lively colour to beds, edging, and mixed planting. It grows into neat, densely leafy mounds up to 30 cm tall, covered with many small red-brown flowers with a soft golden centre. With a long flowering season, it keeps borders looking bright and full of character well into autumn. Its light scent can help deter troublesome pests, which makes it a useful companion for vegetables and ornamental plants.

Sowing depth

Sow Red Gem seeds to a depth of about 0.5 cm. Sowing too deeply can make germination harder, so cover them lightly with a thin layer of soil.

Sowing time outdoors

The best time to sow directly outdoors is from April to May, once the soil has warmed and the risk of frost has passed. In these conditions, seeds germinate quickly and develop into strong, healthy seedlings.

Sowing time under cover

For earlier flowering, sow under cover in March or April. The resulting young plants will be stronger and ready to move to their final position once night temperatures stop falling below zero.

Planting out

Plant out Red Gem seedlings in May, after the last spring chills have gone. By then, plants are well rooted and soon begin to branch, filling empty spaces with compact growth.

Spacing

Space plants at 30 x 30 cm. This gives them room to develop freely and form dense, evenly shaped mounds.

Flowering period

Red Gem flowers abundantly from June through to October. It keeps producing cheerful blooms through summer and into early autumn, bringing steady colour without a break.

Growing

Red Gem is easy to grow. It performs best in a light, free-draining soil that stays moderately moist, in a sunny position. It tolerates short dry spells well, making it suitable for gardens as well as containers. Removing faded flowers regularly extends the flowering period and encourages new buds.
