An amazing amount of hybridizing has been going on with Echinaceas in the past few years.  It seems every year, there are more new varieties coming out.  We are growing many of these new varieties at Acorn Farms, and most have worked pretty well for us.  And, most of them are a big improvement over older varieties.

The Big Sky™ Series was developed by Richard Saul of ItSaul Plants, these new varieties exhibit more compact growth habits, and good branching. The flowers have wider petals than the species, and are available in a much wider range of colors.

Another plant that has seen extensive hybridizing, many of the new Heucheras have been bred with H villosa, which gives them great tolerance for summer heat and humidity.  there are many new, non-fading colors in Heucheras, from chartreuse to peach, to almost black.  All are a big improvement over 'Palace Purple', and other older varieties.  Some of the new varieties, in addition to having attractive foliage, also rebloom.

A new series of Asiatic and Oriental lilies that were bred to stay short, and yet have high bud counts, and thus more blooms.  They come in a wide variety of colors, and are great for forcing, as well as for planting in the landscape.  Most of them naturally grow 12-14" high, no growth regulators required.  We grow several different crops of Lily Look lilies, so we have them blooming at different times.  Hardy lilies are great for providing color in the landscape. They naturally bloom early summer, just before daylilies bloom.  We grow about a dozen varieties of Lily Looks:

Lilium 'Tiny Bee'

 -- deep yellow
 

Lilium 'Tiny Ghost'

-- deep reddish purple

Lilium 'Tiny Hope'

-- red
 

Lilium 'Tiny Icon'

-- bright pink

Lilium 'Tiny Nanny'

 -- pure white
 

Lilium 'Tiny Puppet'

-- dark red

Lilium 'Tiny Sensation'

Lilium 'Skyline'

Lilium 'Tiny Todd'
