Nature photographer Maria Firpi says to keep an eye out for hummingbirds and bees! good luck!

  • Looking forward to more info on these.

    Has anyone grown either of the “giant” milkweeds (Calotropis gigantea or procera) totally indoors under artificial lighting? Thought I’d plant in 5 gal pot – makes it moveable and no ground space. We’ll talk about what it takes to grow those first- we know that’s why a lot of you clicked. Firebush is a Florida native and has unique yellow and orange flowers. This sprouted amazingly fast! Tried several times to pinch or even cut to “ground” to encourage bushier growth – and sometimes did get a second branch to grow for a while – but it would eventually lose it’s leaves and wither. I will retype it.

    I received Calotropis Procera seeds from smartseeds a few weeks ago, soaked them in water overnight, and planted them.

I kept the soil damp but not overly moist.
    The seeds germinated in 2 days in very low light but I’m sure a lot of light would be helpful.

  • amazingly enough, one popped up in a pot that i thought had some dahlia bulbs in it outside, it was impressive to see the rapid growth and i transplanted it to a more sunny location, i had to look online to find out what it was, i had never seen this before, your site nailed it right down, its not the tree…cant wait to see the flowers..thanks from s. california

  • I would also like to add to my previous question. The giant milkweed makes a great attractant for butterflies to flock to in your garden as it is considered a butterfly magnet. Do you have any thoughts about how this plant does when transplanting?
    Appreciate any ideas…..perhaps I should just plant it in a pot instead, but I wanted to see how big it will grow in the ground.

    • Hi Bruce, If our five year plant comes back (I’m not certain whether its dead or dormant) I am going to plant it directly on the south side in full sun. We’ve been growing giant milkweeds for three years in Savannah, Georgia, and I am pleasantly surprised. I think this is a tougher variety for them to chew because the leaves are so thick. Of Florida’s 21 native milkweed species, there are only a handful you can easily raise at home. more info. A tad tired of the tropical milkweed here in FL.

      • do you have any more of these? I have pictures but I don’t know how to send them in a comment.

      • tony- i have 3 of these plants doing ok in pots producing many flowers but i do not notice any seed pods, is there an image or any further info on how to harvest seeds?
