Quote from: Anthony Darby on October 03, 2009, 09:04:27 PMIan, I have several pots of Arum pictum, but although the tubers multiply, I have only flowered it once. Before the summer I show my pupils a stem of cotton bolls bought for £2.50 in IKEA. Needless to say, they though it was fake and couldn't be convinced that cotton came from a plant. I removed one boll, extracted the seeds and planted them. One plant is now flowering in the classroom.I am amazed. That quickly! Is this an annual? I thought cotton grew as a shrub with much slower throughput.CheersGöte

Anthony did you look in the green areas to the north west and south east of the fort?
I have been growing Eryngium leavenworthii on several occasions, but the intense purple colored bracts and stems of this annual eryngo never cease to amaze me. It doesn't set seed for me here in Sweden, but it is easily raised by seed, and if sown early in the year the plants reach flowering in late September. It has kept on flowering in spite of temperatures below freezing. Would probably look good in dried arrangements too.1) This first picture is from September when the plants started flowering2) The plants are one stemmed and branch in the top half. This picture shows about half a dozen plants grown close together.3) The stamens are cobalt blue and the bracts are positioned both below and above the cylindrical umbel.4)....I'm out of words !
