Hoped for more

I was really looking foward to growing these from seed. The packet said they needed to be cold stratified (it was recommended) and that I did. I put half the seeds straight into the fridge in the packet and the other half was sown in moist medium (that I put in the fridge). I did notice that some of the seeds appeared a bit smaller and misshaped than usual. I left then in the fridge for about 6 weeks and then put them under a heat-mat (sowed all the packet seeds). Only three have sprouted- mind you I sowed the seeds in early March and we're near April. I'm just going to wait and see if anything else pops up. Its pretty disappointing because I really would've loved having a big group if these milkweeds to give to friends to help establish Butterfly sanctuaries. If else, I'll just grow the three seedings I have and will hope to eventually collect seed from them.

Owner Response: Hi Daniel, We would love to help. Please feel free to contact our customer service or our horticulturist to troubleshoot issues. We do want to clarify that stratification is a cold, moist period so the second method you described (if enclosed or covered to preserve moisture) is correct vs. just putting the seeds in the fridge. A heat mat is not necessary for native species like this and is not recommended as it may be too hot to encourage germination (mimicking mid-summer soil temperatures rather than spring). Lastly, these seeds, even in ideal conditions can take a month to germinate, that is the time from after they have been stratified so they may require some patience. We also have an article about milkweed that you may find helpful, it is linked in the "Learn more" tab of this product page. Rest assured that quality is very important to us and our seeds are tested frequently by a third-party laboratory to ensure germination rates exceed federal and our own standards. Let us know if we can help. Happy gardening!

I was looking forward to growing Milkweed. That's not what I got when it grew. There must have been an error when the seeds were processed. I ended up with amaranth. I have never planted amaranth in my yard. It's so disappointing.
Sandra Johnson from CO
Owner Response: Hi Sandra, Amaranths are a favorite of birds and are spread about by them from amaranth in gardens and it is a very common ingredient in birdfeed. The seeds are very tiny and shiny, very unlike milkweed seeds and would not have come from the seed packet. We are always happy to help you troubleshoot germination issues like it appears you had here. A customer service agent will be contacting you, but I wanted to make sure to note that these seeds should be fall/winter sown or stratified indoors for success (see seed packet). I hope that helps.

Great plants
