2015 "Top Performer" Perennial

Electric Avenue Coreopsis from Creek Hill/Eason (Coreopsis verticillata 'Mayo Clinic Flower of Hope'PPAF or ‘Electric Avenue’)

Bright yellow flowers covered the plants over a very long bloom period . Plants were sturdy, compact and uniform from spring to fall. Fine textured foliage and a nice flower shape contributed to a very pleasing overall affect. Overwintering survival was impressive both years compared to many other Coreopsis in trial. This was designated as a winner of the “Too Good To Wait” award in 2014 and did not disappoint in 2015 either.

Beyond Blue Fescue from Skagit Gardens (Festuca glauca 'Casca11' PP #23307 )

This fescue was considered to have the best “blue” color out there! Plants maintained a nice “ball” shape and did not open in the middle. Plants were very uniform even after two hard winters and three growing seasons. Flower stems were very few in 2015 and faded into foliage for a superior appearance. This is an improved variety over older ones for foliage color. This was designated as a winner of the “Too Good To Wait” award in 2014 and did not disappoint in 2015 either.

The Perennial Trial Committee likes to award ‘Top Performer’ to plants that have been in the ground 2 winters and 3 growing seasons. This category is to acknowledge an upcoming plant that has been in the ground one winter and two growing seasons and has shown excellent performance thus far in the trial. The following two plants impressed the Perennial Trial Committee so much that they designated the category name: “Too Good to Wait Performer”.

    Alexanders Great Brunnera from Terra Nova Nurseries, Inc. (Brunnera macrophylla ‘Alexanders Great’ PP25,789)

    This is a unique Brunnera of “monster” growth proportions which is an excellent choice to add structure to the garden. The large size also helped show off the heavily silvered leaves resulting in a dramatic statement for the garden. It makes a great foliage plant for shady areas but also had a good display of blue flowers that created a light, airy appearance.
