The pale flowers with dusky lavender standards emerge abundantly and fill the evening air with genuine fragrance, a quality increasingly rare in modern ornamental breeding. Each stem produces roughly five blooms, and the plant's willingness to keep flowering when you cut regularly makes it a generous performer for the cutting garden. Growing to 6 to 8 feet tall, it demands a sturdy support but repays the effort with reliable, scented color from early summer into fall.
Signpost Sweet Pea exists purely for visual and olfactory pleasure. These flowers are cut for bouquets and arrangements, particularly valued for their fragrance and the substantial stem length they provide. They're especially striking in evening light, when their scent becomes more pronounced, making them a choice bloom for late-day garden enjoyment or evening entertaining.
No timeline data available yet for this variety.
Start seeds indoors in a chilly, semi-protected location about three months before your last spring frost. Keep soil temperature between 50 and 70°F for germination.
Transplant seedlings outdoors about 6 weeks before your last spring frost, when plants can tolerate cool spring conditions. Space transplants 8 inches apart in rows 36 inches apart.
Harvest flowers when they've opened fully but while still fresh, cutting in the cool morning or evening hours to maximize vase life. Cut when blooms are at peak color and fragrance; pulling or pinching spent flowers from the stem also promotes new bud development.
Cut flowers frequently and remove spent blooms to encourage more flowers. This deadheading habit directly drives continued flowering throughout the season.
