Can anyone help me locate a supplier of these plants? No one seems to know what I'm talking about when I ask for the plant by name (Alternanthera). thank you
Try using the common name of Joseph's Coat, while searching for sources.
Often grown as an annual in colder climates, this tender perennial is hardy in zones 9 and 10.
Here is a link with more information.

about 8 weeks ago I planted dome seeds that were labeled "spinach - bloomside long standing and I got something that does not look like spinach (photos attached). Could you help me identify what it is?. Thank you!
This looks like Alligator Weed.
This link will help you.

I would like to know the name and information about a plant that dies in the winter and comes back in the spring. The info on the card said ‘tropical plant’. It is burgundy. It has long stems with leaves along the stems.
It appears to be Alternanthera brasiliana. They are not native to the US, and were only introduced to Florida. This is the only place that they can survive comfortably, outdoors.
They are quite invasive, and don't require any special care. Just don't let them get even close to freezing. They are strictly tropical.
Changing the soil once every year, and dividing them out can help keep it alive for longer. Feeding will not be necessary if you change the soil and divide every year, or two.
Outside of that... These invasive plants require very little other care.
Groups of burgundy/red seedlings have appeared in very small groups in one area of my garden - I don’t think I’ve planted them and I’ve never noticed them before. Can someone tell me what they are, please? See image.
It appears to be Alternanthera brasiliana or similar. Definitely an Alternanthera, though.

Are they all green or just the new growth? When I look at photos of Plum Dandy, the new leaves look green and the older leaves are plum, as if they faded to plum.
Here are photos from a trial garden and the leaves seem to change colors. You might try giving yours more sun and see if that helps.
