Professional Growing Information I live in eastern Oregon high desert where it's hot (100+) and dry. I have mine in a container. I've read these prefer high humidity, but the plant itself is thriving, However, when the night temps were in the 60's the flowers would all fall off by morning. Now that the night temps are in the 70's the flowers aren't falling. This is a very interesting plant with thick sturdy stems and dark green leaves. As long as you're in the correct zone it should be a real performer for you.

This plant was/is a total bust! I bought two and we had a fairly cool spring so I didn't expect them to grow fast. One even died. The remaining one is about 8 inches tall/wide, decent foliage but that's it. Complete waste of money. I have other mexican petunias that do very well so I'm not inexperienced with this plant.

I agree 100% with Loralei in Texas......beautiful leaves, stems, and growth habit. Very tall and sturdy plant. However, blooming has been very disappointing. I have 10 plants and get about 1 bloom a week. And the bloom last only for a day and sometimes only half a day. I live Georgia zone 8b.

I love the Machu Morado Mexican Petunia. The colour is so true to the colour on the website. I am in Ontario, Canada, zone 6a, and for me, they almost behave like a hardy hibiscus: the blooms open up, last maybe a day, then they drop. Then in a day or two, new buds open up. As other customers said, the blooms are a bit sparse so I probably would not put them in a container and expect them to fill in. But in the landscape the colour is so pretty and so vibrant, the dark stem contrasts beautifully with the leaves... for me waiting a day for new blooms is totally worth it. They will not survive our winter, so I hope I can find them in garden centres next year. Thank you, PW.

I was a little disappointed in this plant. The foliage is great, and as healthy as can be, and growing very large, however, not one single bloom on it. I've grown a lot of Mexican Petunias over the years, and this is the first one ever, that I didn't get a single flower on the plant. I use Proven Winners soil and fertilizer, and it's a great big healthy looking shrub, but no blooms. I have it in a planter, not in the soil. It gets plenty of sun, but not too much, so the conditions are perfect. I just don't know what happened here.

These were in my garden when I bought my house four years ago. I’m in zone 7b, but this plant was invasive, spreading several feet in all directions from a single plant. The lush, dense thicket of plants was five feet tall. A year after trying to remove it, I’m still fighting volunteers; it resprouts from the smallest node fragment. That said, pollinators love it, deer don’t bother it, and it’s beautiful. I’m allowing brave pioneers to grow in my now-diverse pollinator garden, and I will enjoy the ones braving my shade garden at woods’ edge across the yard. I first noticed this plant when I lived In Florida, where I guess it was manicured into polite behavior. Now I know it better; nice to know some living creature likes our increasingly hot climate of Piedmont NC.

I bought these at my local garden center, on the container it says it’s a perrineal, I sure hope that’s right. Anyways I love the purple blooms, very plentiful. Will definitely buy more!

They have a lovely structure and great leaf color... BUT barely any blooms. Out of the 5 plants we have planted they probably average a few blooms total per week by late August in zone 5b. Nice looking plant, but would only plant again for leaves and structure, not blooms.
