Here are a few fantastic Perennials for Spring 2013! Next week we'll highlight new shrubs.

Coreopsis x ‘Mercury Rising’

If we had to pick just a few new items that are absolute must-haves this year, ‘Mercury Rising’ would certainly top the list.  This new zone 5 hardy red Coreopsis is from brilliant hybridizer Darrell Probst in Massachusetts.

Growers have observed no signs of powdery mildew throughout a humid growing season.  The breeder notes that this variety has excellent disease resistance compared to Coreopsis verticillata hybrids.

From early summer through early fall, potentially even until frost, the attractive foliage is covered in lustrous, velvety wine red blossoms with a golden orange button in the center.  Some flowers are lightly frosted with a touch of creamy white on the petals.  The flowers expand as they age, maturing to a large 1 ½ - 2” size.  Even the backs of the flowers are decorative: creamy yellow with a purple stripe down the center of each petal.

Butterflies and honeybees delight in these beautiful blossoms.  Since ‘Mercury Rising’ is sterile, no deadheading or other maintenance is required to keep it blooming over a long period.

It has overwintered in the breeder’s garden in zone 5 (central Massachusetts) for three years and has survived sub-zero temperatures there.

It is a continuously blooming plant that combines well with almost anything else in the perennial border. This new Coreopsis promises to become a favorite of gardeners and landscapers alike no matter what their gardening skill level.

Coreopsis is easy to grow, making it a good choice for beginners. One plant will provide you with long-lasting cut flower bouquets all summer long.

Lychnis ‘Lipstick’

Also known as Maltese Cross,this hardy perennial is native to Russia. Huge, lipstick-red blooms are offset by bronze foliage on this drought-tolerant beauty. Lychnis Lipstick will grow to be about 48” tall and is deer resistant.  Hardy to Zone 4.

Grow this plant in full sun or partial shade. Lychnis blooms all summer.

Pardancanda norrisii

Known as Candy Lily for the variety of colors! This unique eye candy  perennial produces flowers with a variety of patterns in a kaleidoscope of color. Since each plant bears different colored blooms, it is best to buy them when they're flowering so you can choose which color you want. This plant blooms mid to late summer. The plant grows 2-3' tall and 1-2' wide. Zone 5 hardy!

After blooming, shiny black seedpods are formed and are quite beautiful. Green, sword-like foliage.

The genus Pardancanda (Candylily) was developed by crossing Belamcandachinesis with Pardanthopis dichotoma. The resulting genus combines traits of both parents.


Thelypteris decursive-pinnata - Japanese Beech Fern

Beautiful, lush green foliage produces a graceful form. Offsets on short runners eventually form large colonies in moist or dry shade. Popular for shaded rock gardens and naturalizes in mixed woodlands. Herbaceous It has been in the trade for some time, but is still underutilized since it hasn't been readily available. No more! Thelypteris decursive-pinnata is a vigorous spreader and an excellent choice for a groundcover. Beautiful, with graceful fronds, it produces large colonies in moist or average shade. Its vigorous growth is produced on short runners so it is easily controlled if necessary. Arching fronds are a lustrous dark green and have a lighter green underside for a unique display. Japanese Beech Fern appreciates a little extra moisture in the soil to perform best, although it is not necessary for plant health and appearance. It may be evergreen in warmer zones and is fully perennial to zone 4.

Sporobolis wrightii 'Windbreaker'

Formerly named 'Mesa Form', this statuesque prairie dropseed comes to us from the breeding efforts at the Los Lunas Plant Materials Center in NM. Originally bred to be a wind barrier, this form has a commanding presence with its sturdy, upright habit, medium green, strap-like foliage and very showy flower spikes that appear come summer. An herbaceous alternative to expensive fencing, 'Windbreaker' is also a terrific native substitute for pampas grass. Grows 7-8' tall and 6-8' wide. Zone 5 hardy.

'Alstroemeria 'Mauve Majesty' - a hardy Alstroemeria!

Mauve Majesty' is a new cultivar of Alstroemeria with mauve colored flowers. It has vigorous growth and cold tolerance (to USDA zone 5). This 2007 introduction from Cornell's Mark Bridgen makes a compact clumper, topped from mid-June through September with abundant clusters of 30" tall, sturdy, upright spikes that end in rosy-pink flowers, two petals of which are highlighted with a yellow base. Because Alstroemeria 'Mauve Majesty' makes a tight clump, it is perfect for a small space in a small garden. Alstroemeria 'Mauve Majesty' has been a great performer in our trials, and a hummingbird hangout.
