I agree with Donna that they are zinnias, and they look like Profusions of one variety or another. They don't look like Magellans. Is that more than one plant, or are those white flowers just pink ones that have faded? In answer to your question, yes, you can save seeds from them. They should come relatively true from seed. ZM

The sprout pictured above came up in a pot of Dracaena and Philodendron. I do have a pot of babies that I confiscated from my Mom. Those didn't mind being separated and replanted farther apart at all. They did lose at least one leaf each, but have grown many more since doing that in early summer. I've always disturbed the bottom and sides of my big parlor palm clump when repotting, occasionally separate one from the herd to give away. Never noticed any adverse effects. Curious what else people are doing to these palms besides disturbing roots that's causing them to make this observation. I don't think the factor adversely affecting the health of their plants in conjunction with repotting is root disturbance. I would be more suspicious of large volumes of un-root-occupied soggy peat at the bottoms of new, bigger pots, possibly in conjunction with a totally different texture of soil inside the root ball as the new soil around the outside... as seems to be the case with any other similar myth, "prefers to be pot bound" and "won't bloom until it fills its' pot." This thread makes me want to ID which individuals in my pot may be male, which female. I wouldn't want to give away the last of either... Like any committed plant junkie, if any plant can make flowers/stolons/babies/change colors/aerial roots/mature leaf form, or especially balls, I want mine to do it.

I have not tried uploading pics here, but I can tell you, honey tangerine, if by that you mean the variety 'Murcott' (the Florida sense of the term) normally comes true-to-type from seed and often begins flowering in the 3rd or 4th year from seed.

There's a lot of them, but the most fundamental one that I can remember is the Hoagland's solution. You can search the net for Hoagland's solution and it will give the listing of all the ratios of all essential nutrients. One thing is that some elements like Nickel or Cobalt are required in the ppb range, luckily for most well water, this is a contaminant needed by the plants but doesn't affect humans at that level, but these are present in Hoagland's solution. With that solution you are sure that you did not miss out on any essential nutrient. The Hoagland solution is generic and may not be best suited for citruses, so you will have to adjust the correct ratios of NPK but for sure all the trace elements are present. Some trace elements may not be essential for other plants or are still essential but in undetectable quantities. Some hydroponic nutrients are better than others because they target specific plants, so read the ingredients and ask if it supplies all essential nutrients for targeted plants. I actually did purchase the trace elements only from eBay and mix that with Best formulations for NPK, then used it to grow my bananas in pots using coconut sawdust. The banana is now blooming after two years in a pot. The pot size is 20 gallons, and the banana is 7 ft tall at the trunk. The blooming and fruiting is a sure sign that I have met all the minimum essential nutrient requirements to complete the life cycle of a plant. Bananas were feed essentially only with my formulation and city's water. I still have a lot left of my original 1 lb trace elements, I just perhaps used 2 oz of it to mix with the majors 6-20-20 fertilizer, to make sure banana's required essential nutrients are satisfied. Since I use manure on my potted citruses, I don't worry about adding all the essential nutrients or same formulations for citruses, only at certain times when I don't know why it is still yellowing during the warm season and there are no obvious disease or pest problems.
