Trial Garden Update

Every picture tells a story, so today's post is photographic journal of what is looking good in our trial garden. Our test garden is a fantastic resource for our nursery. It is a big investment to maintain such a large garden, but It allows us to test new plants and compare them to older cultivars.

It is here that we learn about a plants traits, both the good and bad, and determine if a plant is good enough to be introduced. Here is a sampling of plants that caught my eye over the last few weeks. What do you like and why?  


Calycanthus 'Aphrodite'



Festivus Gold a new compact ninebark from the Netherlands with bright gold foliage

Black Lace Elderberry is at its best when you let it grow big

Golden Glitter new variegated selection of Halward's Silver dwarf spirea. Every inch is covered with flowers.

Summer Wine Ninebark is wide, cascading shrub that flowers all along the stems.

Glow Girl Spirea is as neat as a pin without pruning. Great flowers, foliage, form and fall color.

Flowering Shrub Evolution - Part II


Lo & Behold Dwarf Butterfly Bush

In my last post I wrote about new breakthrough plants that have changed the evolution of flowering shrubs. This post continues the discussion, and I've listed the shrubs that I think have changed the way we think about, and use them in our gardens and landscapes.


Have I left anything off the list? Send me your thoughts and comments.
