Today I'm going to talk about a plant by my front door that I just love, Daphne odora marginata or Winter Daphne. It's a small evergreen shrub that gets to about 2.5 feet tall and 3 to 4 feet wide. It has shiny green leaves with a small variegation around the margin. The amazingly fragrant flowers appear in small pale pink clusters in early spring.
This is a hardy plant. The problem is, last Winter with our huge snow storm and this year before even the official start of Winter, we've had several days with low temperatures in the teens and even below! When this happens, without any protection, the leaves get burnt and turn brown. Not too appealing when those flowers start to pop out in the Spring.What to do?
Sometimes you'll see people put a sheet over them or some brown paper bags. My solution is Christmas lights! Not only are they pretty, they also produce a few degrees of heat, which is just enough to protect the leaves and flower buds even down the the 9 degrees farenheit we hit in my garden last week. Here's an important thing to keep in mind: don't use the new LED lights! You'll save money on power, but they hardly produce any heat. Use the old strings of twinkle lights that have the little bulbs in them.
For a little extra protection, you can also put a light sheet or thin tarp over the top to help hold in some of the heat.I'm using a string of "Net lights" that I can just drape over the top of it at night, and easily pull off in the morning so as not to permanently weigh the plant down to the ground and turn it into a groundcover.
These techniques can be used on any marginally hardy broadleaf shrubs like this Daphne, Bay Laurel, Hebes, and Hardy Gardenia.
Lesson learned!
Okay, next year I'm going to follow my own advice and use the lights combined with an old sheet. As you can see from this picture, the net lights were not perfect and a few branches poked through.
These branch tips are not dead, but the leaves are brown and ugly and won't be very attractive next to it's gorgeous flowers. I would have cut these stray branches off anyway to keep the shape balanced, but not until I've enjoyed the flowers.
