My Dyckia 'Yellow Glow' has set seed...but
Comments (12)I'm not sure I completely understand your question, Patris, particularly the part about instability, but an albino seedling has no chlorophyll and is therefore doomed to death. With variegated broms there seems to be a direct relation between the color of mommy plant's leaf margins and what goes on in her ovaries (seed pods), so albomarginated plants typically produce albino offspring, whereas mediopictas produce plain green ones. This is neither. There's no striping here of any kind, so it's harder to predict, but the fact that the pods are lacking in chlorophyll seems like it could be an indication that the seedlings will be as well. Of course yellow coloration is not as lacking in chlorophyll as pure white, and the fact that Yellow Glow can turn green in low light/high nitrogen conditions may mean the seedlings will be able to do the same. Stay tuned and hopefully we'll all find out!...See MoreWhat a difference a little heat makes
Comments (52)ReptiTherms are good, reliable heaters and should last years if you treat them right. Attach them to something stiff. They won't tolerate being bent back and forth like a medical heat pad. They're made to be stuck to the underside of a aquariums. Other heaters will work just as well, I'm sure. I also have seed warmers. They don't get nearly warm enough. And I use a microwaveable disk, but it has to be microwaved several times a day. Medical heat pads are warm enough, but newer ones shut off automatically after an hour. Reptitherms are available in different sizes, which is nice. The small one could even be stuck to the side of a pot. Other reptile heaters like heat rocks and so on might work. I might even try adding top heat, like a thermal bulb or ceramic heater to see if that helps even more....See MoreZinnia seed viability -- ZenMan?
Comments (54)Hello javiwa, " ...how does a layperson determine whether a flower/plant is a F1 or non-F1 hybrid? " If it is seeds, that is usually printed on the packet, because F1 hybrids (F1) cost considerably more than open pollinated (OP). If it is plants, that should be also on the little tag that comes with the plant. Also, you can ask here. " Profusion and Short Stuff appear to be the recommended zinnias that aren't susceptible to fungal diseases. " All zinnias are susceptible to fungal diseases !!! The Profusions, Zaharas, and Pinwheels (Zinnia marylandicas) are immune to Powdery Mildew, but not to other fungal diseases, bacterial diseases, viral diseases, phytoplasma diseases, nematodes, or what-have-you. Powdery Mildew is species specific (Lilacs, Phlox, Zinnia elegans, etc, have their own species of Powdery Mildew, and the Zinnia marylandicas are a new man-made species with 46 chromosomes, and don't have their own species of Powdery Mildew yet. So they are immune to PM. It is just a matter of time until Powdery Mildew mutates and the Marylandicas won't be immune to it any more. But that might take a very long time (centuries or more) until that happens. Or it could happen tomorrow. Wait and see on that. " I'm afraid I don't have the time to cross and hybridize zinnias, as my focus is on raising butterflies. " Crossing zinnias to create your own hybrids can take as little time as you wish. You can transfer a lot of pollen in a few minutes. Ot it can take a lot of time, like in my case, where it has become a year-round hobby. Zinnias differ a lot in how much nectar they produce, so there is such a thing as "butterfly-friendly" zinnias, that produce a lot more nectar-containing pollen florets than average. You could grow butterfly-friendly zinnias by simply buying and growing butterfly-friendly varieties. ZM...See MorePlease STOP using the word SANSERVERIA
Comments (61)A presumption has been made about my education and level of information. I reject the premise that a particular degree is required to form an opinion. I said nothing in rejection of science and did not proclaim it to be anyone's enemy, not even close. I am not now, nor was I then, incensed. But what if I was? So what? The incensed don't matter? I'm amused and having a conversation. My comments are offered in the calmest of demeanors, I promise. I even admit to giggling at a couple of the comments. There is nothing to be gained by turning the discussion into one about me or anyone else making a comment. But if that is interesting, have at it. I reject the premise that my opinion is incorrect or does not matter because I'm unqualified to form it, or that anyone else should be put into that category. I maintain the opinion that it is a waste of time to re-do something that is not made better by the renovation. I continue to non-conform. Nobody has offered an explanation of why plant renaming is necessary, why genetic info should be the basis upon which is manifested, and/or the potential benefit(s) thereof. The comments have been about the science, not the practical application of it. Yes, it's wonderful that info has been gained. No, it's bad to rename plants because of that - in my opinion. It's a silly, arcane issue, but does make for an interesting discussion. My comments will remain in the realm of the issue at hand, not personal. Stush, "Most people do what they like to do not what's most needed or hard to do." I have not found this to be true for most people. But that's not really the point I was trying to make. I want to encourage the scientifically-inclined to put their time and effort into the most beneficial enterprises. Nobody else is going to be the one to cure diseases. Scientists rock! Especially when the results of their efforts are of some benefit....See MoreTiffany, purpleinopp Z8b Opp, AL
