Pseudogynoxys chenopodioides Cons
- 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.
Pseudogynoxys Plant Propagation
- 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.
Flame Vine Growing Tips
- In warm regions, this can be invasive but new plants are easy to pull
- Pseudogynoxys chenopodioides grows well in pots. We grow ours in a 12″ pot and cut back the root system in fall, if necessary.
- Prune vine as needed. It grows back vigorously on fences, trellises, pergola
- 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, native bees, painted lady butterflies, pipevine swallowtails, skippers, sulphurs, queens, zebra longwings and more… (If you know of others, please comment below.)
