Cobaea Seed Germination How to Sow Cobaea:
  • For best results, sow indoors, covering the seed with four times their thickness in soil
  • Alternate the temperature within the medium between 68° F nights and 86° F days
  • Sow outdoors in late spring and cover the seeds
  • Maintain a temperature alternating between 55° F nights and 72° F days
  • Germination takes 10-20 days
  • To prevent the flat seeds from rotting, stick them into soil vertically
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Cobaea:
Spacing: Set out or report into a larger container in May or June, placing the vines in full sun in a rich, light loam that is well-drained

Transplanting: It will transplant easily when the seedlings are large enough to handle

Additional Care: C. sandens tolerates wind but should be provided a lattice or other support structure. For container growth, pinch the side shoots in February or March back to two buds and remove all the weak growth

Appearance and Use:

A quick-growing climbing vine, it is used for screens, shade, and greenhouse growth. Growing by tendrils to 10-25 feet, C. scandens is a tender perennial that is best grown as an annual. From May to October, the green ovate foliage is backdrop for bellshaped blooms that open pale green and darken to purple as they mature. Pest- and disease free
