Petunia ‘Supertunia Royal Magenta’ by Proven Winners. Goodness, I hadn’t grown this one before but it acted as all those other silly plants. It grew like stink and bloomed its head off. Bright color! Understand the key to success with these super petunias (from any source) is to feed them regularly. They demand a ton of food to support all that growth and blooming. If you fail with this plant, it’s likely because you didn’t feed it enough. I’d grow it again in either containers or the full sun garden if I wanted this bright magenta color. Good plant.
Petunia ‘Double Dark Blue’ I must be holding my mouth wrong when it comes to these double flowering petunias. Others get great growth. Mine is just-OK. The singles in this class of plants outgrow the doubles in my garden but… Then again, I’m not a double flower fan so perhaps this is the problem. Your results may vary.
Petunia ‘Blue Wave’ see the above comments about growing these fast-growing plants and this dark violet-blue flower is equally good in my opinion. It’s really a matter of choosing your color as to your preference. “Waves” or “Supertunia” are both good plants but different marketing companies. I love all the ‘Wave’ colors and it’s tough to beat them in the open sunny garden.
The Trick To Getting The New Petunias To Bloom Heavily
The new petunias need a lot of feeding if they’re going to really perform in your garden.
I’d consider feeding weekly, or every second week with a fish emulsion or other organic liquid fertilizer to enable them to perform to their optimum level.
Do You Like This Color Of Petunia
If you do like this Supertunia ‘Picasso In Purple’ from Proven Winners, I’d say go and grow it. It grew really well in my trials and filled a pot completely all by itself.
I just couldn’t resist. Yes, it’s a silly thing but… (seriously folks) we’ve not had a hard frost in several weeks. And yes, it’s April 25 and our regular last frost date is somewhere about 3 weeks in the future.
But I just couldn’t resist.
And I have 249 petunias remaining under the grow-lights in the basement so what’s the worst thing that could happen? I’d lose this (albeit a brave and taking-one-for-the-team) petunia.
I’ve never planted an annual this early in our USDA zone 4 garden but there’s always a first time for everything. It’s planted in the growing zone on top of the dry stone wall surrounding our front gardens.
I’ll keep you up-to-date on Peter (the early planted) Petunia.
I started transplanting annual flowers (petunias) this morning. Well, I started and finished because we only need 200 plants this year for around the top of the stone wall and here and there in the garden for a bit of season-long bloom.
Note: annuals are a perfect plant for carrying gardens through dull spots in perennial bloom times.
This year, I decided not to add too many new perennials to the gardens. I want to focus on finishing the hardscape – the fences, irrigation and other backbone “stuff” a good garden needs. And then I’ll return to seriously collecting perennials for both the gardens and the surrounding rock walls.
I am also adding several Rudbeckia and Echinacea species (they’re germinated and awaiting transplanting as I write) in large clumps in the garden. Yeah, I couldn’t resist big, bright daisies.
Note that having large clumps of one species or variety is an excellent way to create a marvellous show. A single flower – perennial or annual – in the garden looks lost – a clump looks much better.
The one tip I’ll pass along to beginners or intermediate gardeners is to never, ever handle a seedling by the stem.
When you are transplanting annual flower seedlings, handle them by the leaves.
If you handle them by the stem, you may bruise the stem and these may not heal quickly (or at all)
If you handle them by a leaf and you hurt it – oh well, the plant will quickly produce more
But however you handle them, do it as gently as you know how.
