A Climbing Vine for Monarch Butterflies
Pseudogynoxus chenopodioides: Pseudogynoxus confusus, Senecio confusus, Mexican flame vine, Orange glow vine
- Perennial flower for USDA hardiness zones 9a-11b (lows to -6.7 °C or 20 °F)
- Slightly colder zones can mulch and pray
- Fast growing annual in colder regions
- Full sun to part shade
- Height: 10-12 feet
- Spacing: 1-2 ft
- Flowers prolifically with vibrant orange blooms
- Blooms all season to first frost
- Start stem cuttings in water- roots even faster than tropical milkweed
- Sow seeds directly after final frost? I’ve heard several reports this is difficult to start from seed. If you’ve tried seeds, please comment below.
- Long bloom period
- Dark green leaves make a striking contrast with bright flowers
- Stunning centerpiece or accent in the garden
- Best nectar vine for attracting monarchs
- No serious pest issues
- A favorite flower for migrating monarchs
- Must be regularly deadheaded
- Needs overwintering indoors for colder regions, but you can cut it back so it won’t take up much space. Our vine overwinters in a 12″ container.
- In warm regions, this can be invasive but new plants are easy to pull
- Pseudogynoxus chenopodioides grows well in pots. We grow ours in a 12″ pot and cut back the root system in fall, if necessary.
- Deadhead every few days for a bounty of beautiful blooms
- Try an all purpose fertilizer to boost initial plant growth
- Use a bloom boosting fertilizer to promote flowering and root growth
- Average water needs. I found that the vine growth habit seemed to shade the mulch/soil so the plant required less water.
This nectar plant also attracts bumblebees, eastern tiger swallowtails, gulf fritillaries, hairstreaks, honeybees, hummingbirds, julia butterflies, painted lady butterflies, pipevine swallowtails, skippers, sulphurs, queens, zebra longwings and more… (If you know of others, please comment below.)
This is one butterfly vine where I recommend buying plants, because I’ve heard numerous reports about difficulty starting from seed. The good news is, once you have plants it’s easy to propagate from cuttings.
