Spurred Snapdragon Linaria

Sow seeds indoors 6-8 weeks before your last spring frost. Place seeds on moist seed-starting mix and barely press them into the surface, as they need light to germinate. Keep soil warmly moist at 65-70°F until sprouting occurs. Transplant seedlings to individual containers once they've developed true leaves, then harden off over 7-10 days before moving outdoors.

Transplant seedlings outdoors after your last frost date when soil has warmed to at least 50°F. Space plants 12 inches apart in rows 24 inches apart. Harden off seedlings by gradually exposing them to outdoor conditions over one week, starting with dappled shade and increasing sun exposure daily.

You can direct sow Spurred Snapdragon Linaria seeds outdoors after the last spring frost. Scatter seeds on the soil surface and press lightly in place without covering, as they require light to germinate. Water gently and keep the seedbed consistently moist until seedlings are established.

Cut flower stems for vases once the bottom florets on the spike have opened and others are showing color; they'll continue opening indoors for weeks of enjoyment. Cut stems early in the morning when plants are well-hydrated. For seed saving, allow the final flowers of the season to fade and dry on the plant, then harvest the seed pods once they've turned papery and brown.

Pinch back the growing tip when seedlings reach 3-4 inches tall to encourage bushier, more branched growth with additional flowering stems. Deadhead spent flower spikes regularly throughout the season to redirect energy into new blooms rather than seed production, extending the flowering period through fall.
