Our untreated non-GMO Mandevilla Sanderi seeds grow vigorous climbing vines covered in striking pink and deep red flowers that draw butterflies and beneficial pollinators all season long.

The Planting Experience:
Growing Mandevilla Sanderi climbing vines creates a joyful decorative gardening journey. Watch pre-soaked seeds germinate steadily, send out winding climbing stems, fill out with rich dark green leaves, and erupt in countless bold trumpet flowers that liven up dull walls, porches and indoor spaces. These low-maintenance perennial vine seeds turn blank trellises and empty planters into eye-catching pollinator-friendly floral displays that bloom nonstop for months.
General Growing Guide:
Soil Preparation: Use loose, lightweight, sharply well-draining flower potting mix; avoid heavy waterlogged soil that damages delicate vine root systems.
Sowing: Soak seeds in room-temperature warm water for 18 hours to speed sprouting. Sow seeds at a shallow depth of 0.8 cm in pre-moistened growing medium.
Initial Care: Let the top layer of soil dry out slightly between watering cycles, place trays in full sun or gentle partial shade at stable 25℃ /77℉ until seedlings fully emerge within 14–21 days.
Ongoing Care: Prioritize full daily sunlight for maximum blooms, follow moderate watering routine, and apply diluted bloom-boosting fertilizer every two weeks to support heavy continuous flowering all summer long. Train young stems onto trellises for vertical climbing growth.
Please refer to our exclusive variety-specific care guide for winter indoor overwintering, trellis training and seasonal pruning tips.
