The helpful people at Texas A&M Agrilife greenhouse, Leslie Wells, Zane Wyatt, Monica Sheehan, and Jane Dever, let me pick out seeds for three different species of cotton, G. aridum, G. nelsonii, and G. therberi. I picked each on the basis of either some story I could tell about them to accompany a painting (nelsonii and therberi), of for the striking difference in how we perceive cotton should look (aridum).
The cotton needs equal hours of daylight and night, so I plumbed my greenhouse for water and added a grow light (more on these later in a greenhouse report), and a couple days ago seedlings started to appear. Time to first the first seed germinated was about seven days. So far, I have at least one specimen per species, but I would like more; I planted at least eight seeds per species, so if more don’t come up, I will try again. Seeds must be given a hot water treatment of 80 C for 90 seconds before planting.
