Prepare a weed-reduced seedbed for ‘Heirloom Cardinal Climber’ Hummingbird Vine and use the recorded planting season, depth, and light requirements. Press shallow-sown seed into good soil contact and keep the seed zone from drying during establishment. Thin or transplant only when the growth habit and spacing call for it. Leave enough room for mature width and air movement. Bloom timing and final height can shift with sowing date, climate, soil, moisture, and competition, so use listed figures as planning ranges.

Thin once seedlings have several leaves to prevent crowding.

Final spacing should be 10-12" apart and several inches from support structure.

Place ‘Heirloom Cardinal Climber’ Hummingbird Vine where its recorded height and growth habit fit the surrounding planting. Shorter companions can be positioned toward bed edges, while taller stems need room where they will not shade small seedlings too early. If cutting flowers, harvest with clean tools at the stage appropriate to the bloom form. If leaving flowers in place, observe how bloom sequence changes through the season and record which sowing date performed best at the site.
