Customer Questions & Answers

Why are the plants I received not the same color as the ones on the website?

The flowers seem to be a smaller variety when I ordered the grande.
Asked by: Anne
Hi Anne, The colors are the same as you ordered online. What happens often times is that a home computer moniters will pick up the colors differently. The flowers are not a smaller variety when ordered in a different sized container. This variety of Petunia hybrid is well known for their small to very small flowers. I hope this helps Anne. If you are not pleased with Watermelon Charm please give us a call at 734-654-7485 so I can get replacement Petunias to your garden right away! Happy Gardening, Vicki, ProvenWinnersDirect

Customer Reviews

Supertunia Watermelon Charm Petunia 4.25 in. Grande is rated 3.7 out of 5 by 3.
Rated 5 out of 5 by from Excellent plants and superior shipment packaging I ordered 16 Proven Winners Supertunia petunia plants this year from Home Depot and the quality and service were excellent in all respects. Four of the plants were these Watermelon Charm variety and there were four each of three other colors. All plants arrived in perfect condition - healthy, blooming and undamaged - and in a specialized shipping box with individual pairwise dividers that were made expressly for them. This packaging was designed and built to take the fullest abuse of the UPS man! The package said it was packed and shipped directly from the Proven Winners greenhouse, and it was all quite impressive compared to usual online plant purchases. I definitely recommend giving Home Depot/Proven Winners annuals a try this year - I think you will find it worth the price.

Rated 1 out of 5 by from Wilted Flowers I am surprisingly disappointed. The flowers arrived 3 days late and were wilted and dried up. Most of the flowers had fallen off. I will go to Home Depot today to see about exchanging them or getting a full refund.
