We've grown these from seed a few times over the years, but last year I didn't; for the first time, I found a volunteer plant, so that we could enjoy its golden flowers anyway. So we collected seed, and have started them again officially this year.

| Harsono | Nov 23, 2008 | Leaves have strong pungent scent and flavour and are used in Javanese cooking, very high in anti-oxidant. |
| Tami M. | Aug 19, 2009 | I planting this beautiful Cosmo from seed and now have a very large, 4 1/2 foot shrub of greenery with no blooms as of yet. It is almost late August and I am wondering if I will see blooms soon? I am in MO and the plant is getting full sun. Thank you for your help.
Our orange cosmos started blooming over a month ago. But I am still waiting for the pink ones to do their thing. Maybe they just like to keep you in suspense... |
