Euphorbia Polychroma vs. Euphorbia ‘Ascot Rainbow’
When old fashioned cushion spurge, Euphorbia polychroma, was used in the past, it was mainly grown for its brilliant sulfur yellow bracts in spring. Beyond that, it didn’t hold a lot of interest in the garden. Over the past five years, many exciting new euphorbias like ‘Ascot Rainbow’ have come onto the market, and they offer season-long interest in the garden. Euphorbia isn’t just for spring anymore. With very little effort from the gardener, ‘Ascot Rainbow’ offers three seasons of interest in the landscape. Phenomenal foliage and an ideal habit set this variety apart. Every part of this plant is variegated, even the bracts that surround the large clusters of flowers in late spring. It keeps its tight, bushy, upright habit from spring to winter without any pinching. In areas with mild winters, it can remain standing through the winter. It makes an excellent container specimen as well. The key […]

Better Bloomers: Hemerocallis ‘Happy Returns’ vs. ‘Going Bananas’
In twenty years, breeders can make big advancements, and ‘Going Bananas’ is living proof. Twenty years after the introduction of ‘Happy Returns,’ one of the most popular daylilies of all time, there’s a new variety on the block named ‘Going Bananas.’ And it’s threatening to take over the neighborhood. Although the two daylilies share a similar flower color and compact habit, the flowering performance of ‘Going Bananas’ is greatly improved. Even on the sunniest days, the lemon yellow flowers of ‘Happy Returns’ do not open wide and flat like those of ‘Going Bananas’. The flowers of ‘Going Bananas’ are 1 inch larger than ‘Happy Returns’ and appear even larger because they open all the way. These flowers also open consistently, even on cloudy or rainy days. ‘Happy Returns’ is one of the earliest daylilies to bloom and starts 1 to 2 weeks earlier than ‘Going Bananas’. Unlike ‘Happy Returns,’ which […]

Pennisetum ‘Hameln’ versus ‘Desert Plains’
For years, Pennisetum ‘Hameln’ has been the go-to grass for landscapers across USDA Zones 5 to 9. When it was introduced many years ago, it represented a genetic advancement over the straight species. But now there’s something even better. Enter Pennisetum ‘Desert Plains.’ This plant, hybridized by Gary Trucks in Zone 5 Michigan, is an improvement over ‘Hameln’ in habit, fall foliage color, and flowering performance. Though they have similar green foliage, ‘Desert Plains’ forms a more refined looking, upright vase-shaped clump in the landscape. Whereas ‘Hameln’ has little appreciable fall color, ‘Desert Plains’ takes on shades of deep red, orange and gold. It blends well with other fall blooming perennials such as helenium and hardy garden mums. One of the most obvious improvements between these two is the flowering performance. Although ‘Desert Plains’ blooms slightly later than ‘Hameln,’ ‘Desert Plains’ produces showy, 5-inch long, smoky-purple bottlebrush plumes that age […]

Rudbeckia ‘Goldsturm’ Versus ‘Little Goldstar’
Rudbeckia ‘Goldsturm’ has been a top-selling perennial for ages and has won multiple awards since its introduction, including the Perennial Plant of the Year in 1999. So why try something new? While ‘Goldsturm’ is a nice choice, it does have flaws. In Michigan, one of the biggest problems is its susceptibility to Rudbeckia Leaf Spot. Often by the time the plant blooms, the foliage is covered in unsightly black spots. Also, the flowers are produced on tall stems well above the foliage, giving the plant a prairie-like look. In comparison, the new Rudbeckia ‘Little Goldstar,’ introduced in 2011 by Jelitto, offers a more compact and proportional habit, improved flowering performance and some measure of disease resistance. Depending on cultural conditions, ‘Goldsturm’ grows 2 to 3 feet tall with long, strong stems topped with a dome of large, golden yellow flowers from midsummer into early fall. The new ‘Little Goldstar’ forms […]

Battle of the Hibiscus: ‘Summer Storm’ vs. ‘˜Kopper King’
One of the most important achievements in hibiscus hybridizing over the past five years has been the development of indeterminate blooming cultivars such as Proven Winners’ ‘SUMMERIFIC Summer Storm,’ which produces flowers at the top three to five nodes up the stems. Because hibiscus flowers last just one day, many buds are needed to prolong the bloom time. Determinate bloomers, such as ‘Kopper King’ develop flower buds just at the tips of the stems. Thus, ‘Summer Storm’ and other indeterminate bloomers flower for approximately three months versus just one month of determinate types (in USDA Zone 5). In addition to its longer bloom time, ‘Summer Storm’ also features improved deep wine purple foliage and colorful pink flowers with a magenta eye.
