Germination of

Oxypetalum coeruleum

Heavenly Blue Milkweed / Tweedia: Blue Milkweed, Southern Star

Oxypetalum coeruleum

Oxypetalum coeruleum: Soak the seeds in water for 24 hours prior to planting. Sow the seeds in a well-draining soil mix and cover them lightly with soil. Keep the soil moist but not waterlogged and maintain a temperature of 70-75�F (21-24�C) until germination, which usually occurs in 2-4 weeks.

Some of plants may have very have specific germination requirements that may not be covered in these general instructions. 

Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here.  Germination times and germination temperatures are to be a guide only.  Many factors can DRASTICALLY affect this.


It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
