BEAUTIFUL

This plant just kept growing and the blooms where very pretty. And there was lots of blooms.

From elaine | September 20, 2024


Absolutely stunning!

Grow Joy never disappoints. These Black Mamba petunias are stunning !

From Mary | May 26, 2023


Healthiest plant I’ve ever received in the mail

100% order from this place!! They had phenomenal packaging that I’ve never seen before and I’ve ordered plants online many times. I wish I could post pictures - they came without even a leaf browning, I don’t know how…but clearly they know exactly what they’re doing.

BEAUTIFUL AND PERFECT

This flower was chosen to help build a bond me and my partner, and not only did it work! Its blossoming bigger flowers!!!

From Caleb | September 17, 2022


Gorgeous and unique

Gorgeous petunia in a true black color! She took a couple weeks to establish but after that tripled in size. She blooms constantly and tolerates heat very well. Like all petunias, she gets trampled by hard rain but she’s very quick to rebound. Highly recommended!

From Maya | August 04, 2022


Pretty Petunias

Perfectly packaged. Growing beautifully!

From Rachael | April 19, 2022


Didn't know I needed these

I saw these randomly and HAD to have them. I've never ordered plants online but they are perfect. Super black and healthy! Just took a couple weeks to bloom out.

From anonymous | June 17, 2021


So unique!

I've never seen anything like the Black Mamba at any Garden Centers near me so I was delighted I was able to order it online this year. The plant arrived healthy and well-packaged, with a couple blooms already, and it has just kept going since potting it up. This plant likes to dry out a bit waterings, or else it will wilt and shrivel from too much water. The flowers are stunning in the sunlight as they appear black when viewed from the top, but deep purple when viewed from underneath

From Jessica | June 11, 2021


Beautiful and lasted all season

Great flowers, completely covered in large beautiful black blooms. Lasted from Spring, thru Summer and into Fall. I can't wait to start up again next year!

The only reason I did not give it a 5S because it would not allow me to. I have one of these and absolutely love it. I get compliments from everyone who sees it I want more of them.

From anonymous | May 21, 2020


Perfect flowers!

These flowers arrived all the way to Sterling, Alaska in PERFECT CONDITION! I have been ordering from GrowJoy for many years now. I am always pleased with the quality products.

Black mamba petunia

The day after receiving this plant it began to bloom. I actually ordered 2 more after receiving this plant. I’m a big fan of this company.

From anonymous | April 18, 2019


Can't wait!

It arrived in great shape, seems to be happy in it's new pot and I hope to see blooms soon. I'm glad I found GrowJoy.

Black Petunia

It was exactly what I wanted. Had some last year but couldn't find any this year at my local nursery. Will try to same some seeds for next year

From Donia | June 12, 2018


Finally found them!!

I bought these plants last year at my local nursery. Was not able to find them this year. Went online, and this is the only company I found to get them mail order. SO HAPPY, they are beautiful and I can't wait until they go berserk! Fast, safe shipping and a great price. You can't go wrong with this product or this company!

From Deborah | March 30, 2018


Crazytunia Black Mamba Petunia - wonderful plant

I ordered this Petunia last year and didn't know what to expect. I loved it. It blooms more than the Black Cat Petunia I had in the same container, the blooms were just as big but were more graceful. It was vigorous and both mounded and trailed over the edge of the container. Love this plant.

From anonymous | January 15, 2017


So Cool!

Love these Black Mamba Petunia plants! Came so healthy and already 2 Black blooms! Really awesome plant!

From Robert | May 20, 2016


Beautiful

I have ordered these petunias for a couple of years. They always arrive in excellent condition, bloom within days after planting. Will order again!

From Sandra | May 19, 2016


WOW - Just WOW

Such a nice DARK color of the Crazytunia Black Mamba to add as a backdrop to any planter arrangement. I added it to some BRIGHT Pink, and it adds such a wonderful contrast!

From Robin | August 06, 2015


Beautiful plant!

The Black Mamba Petunia plant came in perfect condition and ready to plant. Very pleased with the purchase and plan on buying again from this company.

From Sandra | May 18, 2015
