The following is a guest blog post from Leslie Halleck.
With Halloween just around the corner, I find myself giddy with anticipation. I’ll admit that Halloween is my favorite holiday when it comes to decorating. As the designated “scary house” of the neighborhood, I feel it’s my duty to deliver not only on the sweets when the kids arrive, but also to max out the “creepy” factor. In addition to all the standard decorations that go into creating a house of haunt, I also like to create plant combinations that reflect the season. There’s nothing better than adding plants with black foliage to porch containers to complete the look and feel with some style.
Plant varieties with black foliage are hot right now, but plants with true black foliage are far and few between. One of the newest arrivals is the BLACK DIAMOND™ series of dwarf crapemyrtles. When I first spotted these beauties I knew I had to have at least one, and that they’d be perfect for Halloween container specimens. The plants sport spectacular black foliage that offers up a striking contrast to the five available flower colors. BLACK DIAMOND™ Pure White is my favorite; the bright white flowers against the dark black foliage are stunning. If you’re using the “thriller, filler & spiller” method of container design, these are definitely your thriller (which just happens to work perfectly with our Halloween theme, no?). When mature, these semi-dwarf shrubs reach a maximum of 10- to 12’ feet tall, but can be kept to a container size by tip pruning. Make sure you place them in a full sun location to keep plants in bloom and foliage color strong.
For an architectural modern look, Aeonium arboreum ’Zwartkop’, also known as black rose, is the perfect filler for a Halloween themed container. Aeonium is a striking succulent which forms clumps of tall gray stems that hold shiny rosettes of almost black leaves. These rosettes are often called flowers because of their shape. Another fantastic fall filler for your Halloween doorstep is Petunia ‘Black Velvet’. I adore this variety because the flowers are as black as can be with a velvety sheen to them. Don’t forget about black pansies or violas! ‘Black Devil’ offers up coal-black blooms with a tiny yellow center. They make for the perfect tabletop centerpiece when planted or displayed inside pumpkins.
A good container combination always benefits from a plant that trails over the edge…also known as your “spiller”. ‘Black Heart’ Sweet Potato vine is a vigorous creeping vine with beautiful heart shaped leaves. Foliage color is a deep burgundy to almost black. This annual is easy as can be to grow and can work in a full sun to part sun environment. It will also tolerate dry spells if you forget to water, which is a bonus if you live in a hot climate. All of these black beauties create a striking contrast with combined with silver foliage plants such as dusty miller or Centaurea cineraria ‘Colchester White’.
