Availability: In Stock
True-blue flowers are rare and these aquamarine gems will sparkle in the garden. Flower buds and older flowers are lavender, adding extra flair. Blue milkweed, also known as star of Argentine and southern star, draws in pollinators to its sweetly scented flowers, but unlike other milkweeds, it is not considered critical for monarch caterpillars. This cutting flower adds the perfect "something blue" to floral arrangements. Perennial in USDA zones 10–11; otherwise grown as an annual. In areas where perennial plants are vining shrubs, they may reach 10' over time. Sap is toxic; avoid eye/skin contact and do not ingest. Deer resistant.

Tried these seeds

2 out of 5 stars Mar 12, 2022
I bought a pack of seeds these are more than others and they are not coming up, I have 1 out of all of them that's trying to grow!!! I bought about 10 packs of seeds most are not doing anything! The ironic thing is the moon flowers and trumpet vines are growing and quickly! Supposedly these were the hard ones to grow, so not sure but at $45 for seeds for what I bought I won't do it again! I will go to Walmart Home Depot etc! I bought these seeds thinking for surely this will work and be beautiful! The tweedia seeds 4 59 a pack so I'm disappointed

Owner Response: Hi Jenese, We are sorry you haven't seen great germination with these seeds. A customer service agent will be contacting you to help. Some tips from the packet that you might find helpful are that seeds should just be pressed into the soil or media surface as light aids germination. Because seeds are sown so shallowly watering several times a day might be required to keep seeds and the soil around them moist. Also, these seeds naturally take about a month to germinate so patience is also required along with request watering. Quality is very important to us. Our seeds are tested frequently by a third-party laboratory to ensure germination rates meet federal and our own standards. We hope these tips will help you realize that same great germination! Happy gardening!

I only planted 4 seeds (after soaking seeds in water for 5 days to kick start germination ) and I got a lovely full hanging basket full of blue flowers. Small butterflies and bumblebees love it.
