Wishing for that First Fall Frost

I can't help but look forward to that 1st frost of Fall. I'm embarrassed to admit that the weeds have truly overtaken my garden. What I intended to be a paradise of fragrant and colorful flowers has turned out to be a tangled mess of ugly vines and weedy plants with a few colorful beauties mixed in. The first frost will kill all the ugly things, for which I will be very grateful.

But also, that frost will make some plants better. Turnip and mustard greens are not really tasty until touched by that crisp first frost. Many of our shrubs and trees known for their vivid Fall colors will not color up until nights turn cold.

One of my favorite fall chores is riding the lawnmower around chopping up all the leaves before they are sucked up into the bagger. I then spread them out all over my planting beds. Winter rains (I'm keeping my fingers crossed that they come!) will help the leaves to rot and break down, enriching the garden soil.

Cooler temperatures in the Fall are absolutely perfect for planting and transplanting. Perennials, trees, and shrubs establish much better when put in the ground right before winter. Down South where we are, the ground doesn't freeze, so plant roots continue to grow all winter while topgrowth takes a rest. During the winter, plants can get their roots down deep into the ground to reach water and nutrients before having to expend any energy growing new leaves, stems, and flowers.

But also, that frost will make some plants better. Turnip and mustard greens are not really tasty until touched by that crisp first frost. Many of our shrubs and trees known for their vivid Fall colors will not color up until nights turn cold.

Cooler temperatures make gardening more enjoyable. Last week, the outdoor temperature was 96 and the humidity was so high that our heat index was over 100 degrees, so everything I had to do out there was a real chore. This morning, the cool breeze reminds me of my favorite gardening weather. When temperatures are cool enough to wear long sleeves in the garden, I will think I'm in Heaven. There's just something about working in the garden when it's too cool to sweat that I just love.

While others might dread the cold weather, not me. Is it wrong for me to wish for that first frost of Fall? I don't think so.

Hydrangea arborescens: Wildlife Value of the Smooth Hydrangea

If you have seen the lovely Annabelle Hydrangea, you love her. Hardy, easy to grow, and beautiful in summer, Hydrangea arborescens 'Annabelle' is probably the most versatile hydrangea you can grow in the garden.

Large voluptuous white blooms appear in early summer, despite the severity of your winter or any pruning that might have been done too late, because this hydrangea blooms on new growth. Additionally, Our native hydrangea arborescens, will bloom again in late summer if spent blooms are removed.
Hydrangea arborescens, also known as smooth hydrangea, is native to the Eastern United States. Annabelle is a selection known for its particularly large white blooms that can be up to 10 inches across.

You might already know the beautiful attributes of Hydrangea arborescens, but did you know Annabelle Hydrangea also has wildlife value? Here at Shady Gardens, we try to do all we can to encourage a diverse population of wildlife. Our garden is a sanctuary for birds, butterflies, insects, and mammals of all kinds. Hydrangea arborescens is a favorite host plant for Darapsa versicolor, which is also known as the Hydrangea Sphinx Moth. This Sphinx Moth pollinates the flowers on Hydrangea arborescens, then lays eggs on the leaves.

The Eggs develop into larvae which then feed on the leaves of the shrub. If you find a green caterpillar like the one shown here on the leaves of your Annabelle Hydrangea, you can count yourself blessed, because Darapsa versicolor is rarely seen.

A pink-blooming form of Annabelle has been developed, so look for it at your local garden center or online.

Groundcovers: An Important Part of a Southern Garden

I love groundcovers. There’s just something about them that makes me want to have every one I see. 

Groundcovers can be an important addition to our Southern gardens. They act as a living mulch, helping to conserve moisture around trees and shrubs.  

Many groundcovers are evergreen, so they add beauty to the garden in every season. There are groundcovers that bloom, and even groundcovers that make berries! 

Groundcovers can be found that thrive in sun, shade, and even the most difficult dry shade. 

Whether your taste for plants leans toward the exotic, like Hellebores and Rohdea, or if you prefer native plants, such as native ferns, consider adding them beneath the shrubs in your garden. 

There are many native groundcovers that are evergreen, and some even produce berries, like Mitchella (Partridgeberry). Groundcovers like creeping phlox can help control erosion. 

Ajuga Bronze Beauty
Good groundcovers for sun include the sedums, ice plant, and rudbeckia (Black eyed Susan.)  Certain rose varieties also make excellent groundcovers. 

Ajuga is a great groundcover for crowding out weeds in shade or partial shade. It is not invasive.

English Ivy Overtakes the Garden
Beware of groundcovers that can take over the garden, seeming to eat other plants alive, crowding out everything else. Instead of invasive English Ivy or the popular Japanese pachysandra, try our native pachysandra, Allegheny Spurge. Or if it’s a vine you’re after, plant Crossvine, Carolina Jasmine, or Red Trumpet Honeysuckle—all native vines that will not overtake your garden.
