Days to Germination:16 days
Mina lobata. This classic vine’s long, upright flowering stems stand out proudly from the twining vines of 3-lobed, heart-shaped, dark green leaves and attract butterflies and hummingbirds in droves. Soak the seeds overnight or nick the hard seed coat, and then sow them directly in the garden after all danger of frost has passed, or start seeds in individual pots indoors, 5 to 6 weeks earlier. Keep the seeds evenly moist until germination, which can take up to 16 days. Once all danger of frost has passed, harden off the seedlings by slowly introducing them to the outdoors over the span of a week. Thin or transplant to 12" apart in full sun and moist, rich, well-drained soil. Provide the sturdy support of a trellis or tuteur. Over fertilizing will result in lush foliage but fewer flowers. Annual. Summer flowering. Height: 15'.
