Cosmos seeds - mixed up
Last week I sowed some Cosmos seeds - some red flowers, some white. I didn't label them (foolish) as I thought I would remember which pot was which. I then moved them around when watering them, and am now thoroughly confused !
Does anyone know whether the emerging seedlings will look different, or will I have to wait for flowers before I can tell them apart ? (the white ones were purity, the red sonata)
