We Don't Get Questions
Today’s question comes from me. You didn’t send it in, and neither did that other person reading this small corner of the blogosphere. So I emailed it to myself and then I replied to myself and then I posted it right here.<br /><br />Q: Can you identify this plant for me? It’s mostly green, with spines on all sides. It’s about 4" across, but taller.<br /><br />Thank you,<br />Peter<br /><br />A: It’s a <a href="https://cactusjungle.com/archives/blog/exit.php?url_id=1760&entry_id=1565" title="https://www.cactusjungle.com/plant_pages/euphorbia_trigona.htm" onmouseover="window.status=’https://www.cactusjungle.com/plant_pages/euphorbia_trigona.htm’;return true;" onmouseout="window.status=”;return true;">Euphorbia trigona.</a> As it grows, it can get up to 6" around, and will eventually be a 20′ tall tree if planted in the ground, which we don’t recommend here in the Bay Area. <br /><br />If you do plant it in the ground in this area, you will need to protect the growing tips when it gets close to freezing. We recommend a styrofoam cup on the top of each branch. <br /><br />A frost blanket will work too, but we recently created a tent out of one around a tall cactus in a pot, and then the 65mph winds came blowing through the area last week and the tent became more of a sail than a tent and the plant blew over. Luckily, we know enough to stay away from the nursery until wind storms are over, what with the spiny cactus and all.<br /><br />Hope that helps,<br />Peter<br /><br />
