Growing Crossvine From Seed
- Seeds can be purchased or harvested from the plant.
- The best time to harvest crossvine seeds is in late summer when their pods have browned.
- Once harvested the seeds can be stored for planting at a later day.
- The seeds have an incredibly high rate of germination.
- Plant seeds no more than 2” inches below the soil surface.
- Watering should be done liberally.
- If the soil is not porous, consider adding perlite to the soil mix.
- The soil should be allowed to retain moisture without overwatering.

- The cutting can be planted directly into the ground or a container.
- Only the roots should be buried under the ground.
- Water the root cutting liberally at the beginning.
- Allow it to retain moisture in the soil.
- Softwood cuttings can be taken from any part of the plant.
- The young branches are usually quicker at developing new roots.
