Could be. Darn!! I think I lost all of them. It's funny because the seedlings looked so similar to the peacock flower pride of Barbados, but these all foundered after I potted them up. I'm so sorry! 🙁 @treefrog44
Sharpie. But I noticed it wore off on a different milk carton label... I think some brands are slicker than others... If you want an extra bit of protection, get some clear packing tape and tape over the writing. That holds out longer. @kimguy
Look at my babies @treefrog44 😁 These were the coolest things to germinate! Instructions said it was like simulating a fire. Poured boiling water over the seeds then soaked them for 24 hours. They sprouted almost immediately! ❤️
Popcorn cassia can be grown from seed, but for use as an annual it is more typically purchased as a rooted cutting. Seed will germinate more readily if soaked in water for 24 hours or scarified mechanically or in boiling water. Sow shallowly in February or March.
