The "Cardboard Palm" isn't actually a palm, it's a cycad. Cycads are non-flowering so they don't actually "bloom". There's separate male and female plants and they reproduce sexually (although some can reproduce asexually as well). The plants produce cones rather than flowers, the male cones having pollen and the female cones having the ovules. Edric's photo is of a female cone of Zamia furfuracea, commonly called Cardboard Palm.
Beautiful photo. I hope I'm replying to this correctly! I'm referring to the seeds you intend to propogate. Beautiful. I want to ask a question about my Cycads. I'm having problems with yellowing. I've tested the soil (thinking acid was off), but Ph is 6.5 - should be okay. I have one Cycad in bad, bad shape that does show as low on nitrogen & phosphorous. I'm sure that needs to be corrected, but does this account for yellowing? This plant started out yellowing and kept getting worse. Now all leaves have yellowing and the tips are brown. I have 2 other Cycads & they are in pots. They are yellowing but are actually a bit high in Nitrogen, Ph is okay (6.5 ish), but are low in Phosphorous & Potash. These two are just yellowing so far but I'm afraid they are going down the same road as the first one and I don't know what to do. Would greatly appreciate some thoughts & ideas. Thanks!
Simi is hot and dry and that is probably the cause of your yellowing.. .Zamias like humid and mod warm climates. Hard to keep these from yellowing in a dry climate, particularly in full sun. I have a good friend in Simi who has many of these in his front yard and they are all yellowy. Doubt fertilizer problems have anything to do with it.
