Next Generation Coleus Offers Production Advantages
Coleus has been reinvented so many times over the past 50 years that it is often hard to remember what the plants used to be like. Even the scientific name has been reinvented multiple times in just the last five years. What was once known as Coleus blumei became Solenostemon scutellarioides, which then became Plectranthus scutellarioides, where it rests for now. Originally, coleus was a seed-produced crop used primarily as a houseplant. It was also used as an herbal remedy in tea to help folks sleep. That has all changed in the last 20 years with the infusion of sun-tolerant varieties, late-flowering varieties (to avoid deadheading and extend season of performance), new colors and new forms. In the past 10 years, there has been some very nice breeding for landscape performance and heat tolerance. Over and over, this plant has changed until what we grow today is so superior to […]

Heat Tolerance Sets New Alyssums Apart
The goal of Proven Winners’ lobularia breeding program was to bring a fragrant, easy, all-season performer into a crop that previously had a very limited range of success. The Princess and Knight collection of hybrid lobularia look like sweet alyssum, but appearances can be deceiving. Where old-fashioned seed-type alyssum do well only in Mediterranean climates, quickly dying in the summer in all other parts of the country, these new hybrids thrive in the heat. They have received top marks for performance in summer trials across the Southern U.S., including the Dallas Arboretum in Texas and Costa Farms’ trials in Miami, Fla. While there have been many knock-off genetic lines introduced over the past three years, none of those boast the record of performance of ‘Snow Princess,’ ‘Blushing Princess,’ and ‘Frosty Knight.’ While these plants may look the same, the plants in this Proven Winners collection do not grow or perform […]

‘Superbells Lemon Slice’ And ‘Superbells Cherry Star’ From Proven Winners Break The Color Mold
In the past two years, Superbells Calibrachoa ‘Cherry Star’ and Calibrachoa ‘Lemon Slice’ have changed our understanding of what color patterns are possible in calibrachoa. The breeding programs that generate the Superbells collection have always focused on innovative colors, and over the past few years, have developed some amazing mutations in color form. For a breeder, mutation can be a great way to move groundbreaking breeding forward. They can offer shortcuts to new combinations, increasing disease resistance, overall performance and many other advances. It is mutations of tissue layers within the flower that give ‘Cherry Star’ and ‘Lemon Slice’ a completely new look for the genus. While a muted star pattern has been on the market for a while, these new color patterns are sharp, distinct and heat-stable, resulting in colors that won’t fade as the summer heats up. Innovation Sparks More Innovation What is the value of innovative color […]

Fruit Punch Dianthus Kicks Up Proven Winners’ Product Lines
Proven Winners has announced the release of the Fruit Punch series of hardy dianthus in USDA Zones 4 to 9. This crop is easy to produce and provides color on retail shelves from late spring into summer, often reblooming in fall for the home gardener. Members of this series are all fully double and fragrant, blooming in rich shades of deep red, pink and bicolor flowers. Dianthus ‘Apple Slice’ and Dianthus ‘Coconut Punch’ produce bicolor flowers with deep red edges and pink or white petals. Both of these cultivars are about 10-to-12 inches tall and offer longer flower stems, which are great for cut flowers. Dianthus ‘Black Cherry Wild’ and Dianthus ‘Pomegranate Kiss’ are shorter, more compact cultivars that stand just 6 inches tall in full bloom. D. ‘Black Cherry Wild’ produces deep-velvety-red flowers with a very thin white edge. D. ‘Pomegranate Kiss’ offers unique almost tie-dyed looking flowers in […]

How To Grow Rockapulco
Proven Winners has made its first addition to the double impatiens Rockapulco collection in Coral Reef. ‘Rockapulco Coral Reef’ has a unique color, as petals emerge coral and turn to a bright, electrifying pink as they age. All of the Rockapulcos are vigorous and feature flowers that resemble miniature roses or camellias. Lighting Production guidelines are the same for all varieties in the collection. These double impatiens need higher light levels than traditional impatiens. As with all impatiens, brighter light in production helps control stem stretch and focuses growth on higher flower production. In most regions of the United States, the Rockapulco collection requires no shade in production. But under extreme high temperatures, brighter light can cause minimal flower or leaf scorch. Fertilization Another important note is to watch fertilization rates. Rockapulco and all impatiens are very responsive to fertilizer rates and types. High fertilizer rates, and especially high ammonia-based […]

‘Sweet Caroline Bewitched’ From Proven Winners
One of the only non-vining ornamental sweet potatoes on the market is ‘Sweet Caroline Bewitched.’ Known for its mounding habit, dark purple-black foliage and characteristic bat wing leaf shape, ‘Sweet Caroline Bewitched’ makes a great container plant without becoming a bully, and it’s also great in the landscape–especially in the sunbelt where old-fashioned types can become a maintenance nightmare by spreading 36 inches a week. Still, even with this performance, ‘Sweet Caroline Bewitched’ needed improvements, which led to an improved version Proven Winners has released for 2012 spring sales. So what exactly are the improvements? 1. Color. The improved color is almost totally black, improving on the old form that would fade to green a bit on the oldest leaves. New leaves emerge almost black and now stay black through the plant’s life with no reversions, such as the ones common on the older free varieties. 2. Texture. The leaf […]

‘Intensia Blueberry’ Phlox Is Focused On Performance
The Intensia phlox series, introduced in 2003, was based on an interspecific hybrid with a wild species that gave the series a huge jump forward in heat tolerance, powdery mildew resistance and overall vigor. One of the other advantages to interspecific hybrids is they are usually sterile, or at least produce fewer seed. And because the plants expend less energy in setting seed, that energy instead goes into performance. These are just standard examples of what you should expect to see with this kind of breeding. Better Breeding As with every emerging new crop group, there are always improvements to be made. ‘Intensia Blueberry’ improves again on a great bit of breeding. By changing the parentage of the cross, you get a beefier plant with larger leaves and thicker stems. These two characteristics give growers some improvements from which they can really benefit. One of the weaknesses of this line […]

How Your Retail Plant Sales Practices Compare
Editor’s note: Greenhouse Grower RETAILING asked growers and retailers to share their pricing methods in a survey sent out in mid June 2016. Of the 362 responses, 202 arefrom those whose primary business is garden retail. We will be sharing the results of what we learned throughout July, August, and September 2016. Discounting plants is a finely wielded weapon for plant retailers, Greenhouse Grower RETAILING‘s Plant Pricing Survey shows. It will come as no surprise that just about everyone holds sales at some point (93%). And so it makes sense that some expertise is shown. Take this first graph as an example. The most perishable plants — small annuals and vegetables — are the most likely to be placed on sale. That seems counter-intuitive. Why place the fastest turning inventory on sale? But when we took a closer look, we found that these sales are being used to lure […]
