I attended the Nashville Lawn and Garden Show on the last day. Wouldn't you know, my phone/camera was needing a charge. So, here is one floral arrangement that caught my eye.
As far as the plants were concerned, I found the miniature evergreens of interest and added three new ones to my collection. They grow very slowly and take many years to reach their mature diminutive size making them perfect for trough gardens. These were purchased in 4" pots.
The source of miniatures are witches brooms. Normal size trees due to disease, insect damage, etc. sometimes form growths/witches brooms that are more compact. The branches can be grafted to normal rootstock or they can be started from seed of the broom and reproduce the miniaturized form.
Chamaecyparis lawsoniana 'Rimpelaar' is a miniature conifer with blueish gray foliage that is hardy in zones 5-9. In ten years it will be a foot tall and wide. Mature Chamaecyparis lawsoniana 'Rimpelaar'
Chamaecyparis obtusa 'Spiralis' is a slow growing narrow upright evergreen reaching a height of three to five feet in ten years and is hardy to -30°F. It has a loose irregular upright habit. Mature Chamaecyparis obtusa 'Spiralis'
Chamaecyparis obtusa 'Snowkist' is a white variegated conifer that matures at 24"x18''.
I collected Chamaecyparis obtusa 'Golden Sprite' a few years ago and it can be seen here. I found my previously purchased mini's to not be as hardy as expected in a tiny pot, but in the ground much more hardy.
