Professional Growing Information I planted two of the Black Cherry petunias in a 14" hanging pot. They were a little slow to get going but eventually filled out the pot and grew over the sides. The flower color is a deep ruby red, very pretty. The plants do not have a dense growth habit, and needed a little pruning to keep a full shape. They are not quite as floriferous as some other varieties, but were very nice.

Supertunia petunias are vigorous with slightly mounded habits that function as both fillers and spillers in containers. They are also excellent landscape plants, best suited to be placed near the front of beds. They have medium to large sized flowers.

Maintenance Notes:These are heat tolerant plants, that aren't particularly fussy and need little routine maintenance. They will perform best if an application of controlled release fertilizer is included at the time of planting. This applies to both landscape and container plantings. Supertunias are heavy feeders, but a single dose is usually sufficient for landscape beds in most climates. If you have a very long season, a second application of controlled release plant food should be considered for landscape plantings. In general, containers need to be fed more than landscape plants. Supertunias in containers will need to be fed more regularly to be their absolute best. A second application of a controlled release fertilizer can be applied about every two months to container plants, which will help. However, for the very best performance I find regularly applying water soluble fertilizer starting about two months after the containers are planted gives the best results. These extra applications of plant food really makes a difference in performance through the summer.
If your plant begins to look open or a bit tired, an allover trim can be beneficial. Use a sharp pair of scissors or pruning shears to trim back up to 1/3 of the volume of the plant. I pair any trim with a dose of water soluble fertilizer to provide instant energy to help kickstart new growth, branching and flowering. Your plant will take a week to recover from the trim, but the end result is a fuller plant with more blooms going forward. You may repeat the trim as needed through the season.

I LOVE the Black Cherry Supertunias! For the past two years have had them in a south facing front bed, in a circle with purple fountain grass in the center. This bed needs the least tending of all ( truly no deadheading needed! ). They fill in and mound beautifully and look spectacular! The heat this summer and above rainfall didn't faze them in the least!

This is a great color and grows with good vigor. When the temperature popped up to *100+ for a few days, the blooms showed dead spots. That will change as soon as I feed her again. Sun damage is not unexpected in our summers. The heat doesn't slow the plant just the lack of food. All the time release fertilizer releases at once with the heat so there is a boom and then a hunger. I bought this plant last year and it survived the winter in the open garden bed in zone 9b. I keep chopping it back because it wants to roll and grow over it's neighbors. I am letting it twine in under the Summerific Hibiscus. I don't let my petunias get woody. I gradually cut the tips back and back until most of the plant in on new branching. I am so glad it lived through winter because I have not seen it for sale this year at my local nursery. It's beautiful with Sparkling Ruby Superbena and Blue Laguna

Bought this (admittedly a tad reluctantly) but now highly pleased with this plant. It has grown to the size of a shrub and has hundreds of blooms, despite 6-7 hour of intense, afternoon sun daily with no shady respite. I have only watered, fertilized and trimmed once. The color has grown on me, the toughness is impressive and I look forward to having one of these in 2016. Only caveat...this plant has the potential to dominate others in the same pot.

The only flowers that has survived in my yard this year, I love the Black Cherry adds such a beautiful contrast. The only thing I can say negative about Proven Winners is we have very limited quantities in my area.

These are amazing plants! They've filled in beautifully and have qualities that I admire in a bedding plant. I wouldn't consider them a trailer, like the Sangria Charm, which spill over the edge of my retaining wall brick, but they spread out to meet each other and fill in nicely. Their mounding habit, is what makes them a winner. That, and the fact that they don't appear to be getting leggy whatsoever. What can I say about the color except WOW! We have strangers stopping us as we work outside to ask about these beauties! A total Proven Winner!

The color is so beautiful and its flowers catch the eye!

When planted in a hanging basket it makes a nice compact round basket. It stays full in the middle. It bloomed a little later than some of my other petunia's but it was worth it. The color is unique and outstanding
