Monrovia, the leading grower of premium plants, has introduced 22 exclusive and semi-exclusive new plant varieties for 2009

According to Nicholas Staddon, director of new plants, “Research shows that home gardeners seek out plants that are improvements over existing offerings. So we continue to look for new varieties that are hardier, healthier, more pest and disease resistant and offer interesting characteristics such as habit, fantastic color.”

Highlights for 2009 include Agapanthus orientalis 'Baby Pete' PPAF, a Monrovia exclusive. Baby Pete was chosen for its compact habit and much longer bloom period due to its almost seedless trait. A new African Iris is a Monrovia exclusive; Dietes x 'NOLA alba' KatrinaTM PPAF, a stronger growing, hardier, more floriferous variety that is far less susceptible to crown rot than other Dietes, making the plant a winner for the South and South East.

Another first are three new Chamaecyparis lawsoniana varieties grown on a root stock that is resistant to Phytophthora lateralis – a disease that has caused the demise of many lawsoniana's over the last two decades. This rootstock was developed by Oregon State University and is marketed under The Guardian™ Series. We have used this new rootstock on several varieties: 'Blue Surprise', 'Golden King', 'Silberstar', and 'Yvonne'.

Monrovia's new Itoh Peony Collection will excite gardeners. For many years, it was assumed crossing an herbaceous peony with a tree peony was impossible. After years of research and disappointment, this great feat was accomplished and Monrovia is offering four stunning beauties.

The latest Flower Carpet® rose is the much-awaited 'Amber'. The name reflects the color of the flower when in full bloom, fading to a seashell pink, just beautiful. And here's the big bonus, Amber is the first fragrant Flower Carpet®, this new introduction has all the markings of a winner.

Below is a complete list (in alphabetical order) of Monrovia's 2009 exclusive and semi-exclusive varieties:

Itoh Peony Collection Those who admire the colorful and exotic flowers of tree peonies, put prefer the perennial growing cycle of its herbaceous counterpart, will love the Itoh peonies, also known as intersectional hybrids. In the quest to create a true yellow herbaceous peony, Toichi Itoh, in 1948, was the first to successfully cross a tree Peony (P. lemoinei) with an herbaceous (garden) Peony (P. lactiflora.) Other breeders followed in his footsteps, creating new varieties of stunning color, combining the best traits from both parents. However, these great plants were slow to multiply and far too expensive thus unaffordable to many to become well known by the gardening public. Some divisions were selling for $1,000 each.

This all changed in 2004 when a Canadian tissue culture laboratory discovered the closely guarded secret to produce Itoh peonies in vitro. Monrovia, adept at bringing unique and hard to propagate plants to market, partnered with this laboratory to introduce an assortment of Itoh peonies.

Itoh peonies resemble tree peonies with a domed, vigorous growth habit and large double flowers with disease-resistant lacy, dark green foliage. Like herbaceous peonies, the Itoh hybrids are winter dormant providing decades of enjoyment in the garden. Itoh peonies can provide up to 50 blooms in a single season due to their ability to produce primary and secondary buds. They will grow two to three feet tall and wide. They offer an increased color range, greater vigor, and excellent resistance to peony blight (botrytis paeoniae).
