Weeping Lorapetalum

Lorapetalum - weeping variety, spring

Upright Lorapetalum

Lorapetalum - upright variety, fall

The Lorapetalum is a dense, tight growing, cold hardy shrub with leaves that are ruby red when they first emerge and then range through tones of bronze and varying shades of green.

The leaves are delightful on their own, but then you get the added pop of frazzled fringy pink flowers in the spring and fall. It makes a very attractive potted specimen plant which is how we show it in the garden.

You can see it displayed in our Linnaeus Garden both as a weeping variety (Herb Garden) and an upright plant (Boulder Garden).(2015)

Encore Azaleas

Encore Azaleas

Our garden is sporting some new Encore Azaleas and they are the most cold hardy of all the encore varieties.

If you love Azaleas in the spring and wish that their bloom cycle could happen more than once a year then the Encore Azalea is your answer.

After the spring blooming period, these amazing azaleas begin growing new shoots and start blooming into full flower in mid-summer. They have occasional flowers throughout the entire growing season and can have a flourish of flowers even in the fall.

Hardy Orchid

Yes, there are orchids you can grow outside in the garden. These are called hardy or terrestrial (meaning in the ground) orchids. Growing this group of plants can be easier than you think, provided you choose the right species and pay attention to a few cultural needs.

The main principle for success is good soil drainage. Another key point in success is that they don't need much fertilizer. Usually some compost incorporated at planting, and applied around them in future years, is all that is needed.

Three additional tips will help you have success with hardy orchids. After blooming, remove old flowers. This keeps plant energy going into the roots and not into seed production. When weeding, grasp and hold the orchid plant while pulling weeds. This helps you from pulling up the orchid with the weed. The orchid roots are generally shallow, with the weed roots growing under them. Then for extra winter protection you may wish to add a couple inches of weed-free straw or pine needles on top. If using leaves, make sure they are ones that don't pack down tightly.

This plant has proven to be a showstopper. This alluring plant cries out for attention with its beautiful spring flower display, gray-blue summer foliage and exceptional, rich-red leaves in fall.

Of all its favorable attributes, the striking blue hue is what really sets this Fothergilla apart. It's a winner in landscapes and provides a sharp color contrast to companion plants, particularly those with golden foliage. 'Blue Shadow' forms a dense network of angular stems.

In April to early May, 'Blue Shadow' will dazzle bystanders with honey-scented, bottlebrush flowers. Outstanding blue leaves soon follow. In mid-October to late November, fall colors appear. Rich red dominates and is often accompanied by shades of orange and dark yellow, so this plant has seasonal interest galore.
