I think you'll have much better luck this next time around. :)
Here is a picture of my portulaca seedlings. They are much less vigorous than even my ornamental purslane seedlings. They sprouted quickly, but most of them died off and this is all that I am left with.
You may also see a volunteer moringa seedling growing in the same pot. Anyone who lives in a warm part of the world should consider growing a moringa. Their leaves, flowers, and their young bean pods are edible and very high in vitamins and minerals. They are great in salads and in smoothies. They grow extremely fast, but in my experience, it is best to keep pruning them (and eating the prunings) to prevent them from becoming a tree, or else they will get huge, and the leaves and flowers and bean pods will become very difficult to harvest. They sprout easily when the weather is hot. The best way to get them going is to save some mature seed pods and keep them dry and inside your house all winter and early spring (because they have no dormancy period at all), and then when it starts getting hot outside, just dig little holes in the dirt and plant them about one inch deep and water them. Within about 1 week, they will sprout and start growing. They have a huge taproot, and after they get established (after one full growing season) they only need to be watered about once or twice a month, even in Phoenix, Arizona. They are sensitive to frost, but will recover quickly once the weather warms back up.
And over here is some ornamental purslane...
And here are the last of my ornamental purslane seeds that have sprouted and are growing. I will order more of these seeds for the spring season, and try them again. I liked them very much. There is also a volunteer moringa seedling growing in their pot, too. There are also some Egyptian spinach volunteers growing in there as well.
