Plants of the Year

Plants of the Year – 2014

Lots of organizations designate special plants of the year to highlight plants with great features and help gardeners choose plants to add to their landscape.  Here are some of the choices for 2014.

The Delaware Nursery and Landscape Association (DNLA) has been choosing a woody plant (tree or shrub) and a herbaceous plant (one that dies back to the ground each year) yearly to promote to Delaware gardeners.  A selection committee that includes industry members, garden writers, university professors, local landscape designers, and local landscape consultants comes up with a list of plants that meet the criteria each year.  The plants must be available in the nursery trade (nothing is more frustrating than reading about a plant and then not being able to find it to buy and plant in your garden).  They must also grow well in our region, have few pest and disease problems, provide an interesting or showy element to the garden and be somewhat underused in the Delaware landscape.  What is the point in promoting a plant that is already overused!  Then the DNLA board of directors’ votes on the plants they think best meet the criteria from those nominated plants.  Everyone has their favorites and the discussion can get sticky at times, but the process routinely churns out great plants that Delaware gardeners will enjoy in their home landscapers.  The two choices for 2014 are:

 Paperbark Maple (Acer griseum) – This small tree grows in moist, well-drained soil in full sun to partial shade. It has an oval to oval-rounded habit and is known for its peeling, cinnamon to reddish brown bark. Trifoliate leaves are dark green, but turn red in the fall. Its seed is a two winged samara.  It has no serious disease or pest problems. Paperbark maple is a slow grower (6 inches – 12 inches per year) and makes an excellent tree specimen tree for small properties. It is appropriate as an understory tree in a woodland garden or as a specimen in many locations around the home.

Christmas Fern (Polystichum acrostichoides ) – This fern is best grown in organically rich, dry to medium moisture, well-drained soils in part shade to full shade. It will tolerate a dry site better than most ferns. Christmas fern is a local native that can be found on both dry and moist wooded slopes, moist banks and ravines. It typically grows in a fountain-like clump to 2′ tall and features leathery, lance-shaped, evergreen (green at Christmas time as the common name suggests) fronds. While it is considered evergreen and provides winter interest (unless the ground is covered in snow!), the old foliage is pretty beaten down by the end of the winter and gardeners will be looking forward to young fiddleheads emerging in spring. There are no serious insect or disease problems. But, avoid planting in poorly drained soils, where crown rot can be a problem, particularly in winter. Christmas fern looks great in woodland gardens, shade gardens or shady areas of borders, wild or native plant gardens. It can be planted in shady areas along walls or foundations. Christmas fern is a good plant for massing on slopes (including dryish, rocky ones) to help combat soil erosion.  Another big benefit in our area is like all ferns, Christmas fern is deer resistant.

 The Society of Municipal Arborists has named Persian ironwood (Parrotia persica ‘Vanessa’) as their 2014 street tree winner.  Parrotia was chosen for its many merits including resistance to drought and pests, upright habit, hardiness, slow growing smaller size, fabulous fall color and interesting bark.

Northwind Switchgrass with Juniper

The Perennial Plant Association also picks a plant of the year and for 2014 that plant is Northwind switchgrass (Panicum virgatum ‘Northwind’). This tall ornamental switchgrass has a distinct vertical habit. It is the sturdiest of the cultivated switchgrasses – guaranteed not to flop. Olive-green to blue-green foliage turns tan in the fall and along with its airy flower panicles provide great winter interest.  By the spring, this still-bold foliage has almost a white color and looks striking when combined with an evergreen, like Eastern red cedar (Juniperus virginiana). It looks so good, it might be hard to cut back the foliage in the spring to make room the new growth.  But, never fear, Northwind switchgrass will grow back quickly and provide a great backdrop for other plants in the garden.

The National Garden Bureau picks a flower, vegetable and perennial each year to showcase and the 2014 choices are petunia, cucumber and Echinacea (coneflower).  There are many great new coneflower cultivars available.  In 2009, Mt. Cuba Center conducted an evaluation of many Echinacea species and cultivars for our region.  A copy of the results can be found at

Not be outdone, the International herb association also picks an Herb of the Year™.  The selected herb must be outstanding in at least two of the major herb categories—medicinal, culinary or decorative.  The 2014 Herb of the Year™ is Artemisia. This diverse herb family contains many strikingly different plants, from the highly decorative Artemisia ludoviciana ‘Silver King’ to the delicious and tender French tarragon (Artemisia dracunculus ‘Sativa’). Artemisia has a long history, prominent in folklore, its virtues used in numerous ways: to protect and heal, create tasty beverages and foods, decorate the home and work its magical properties.

Finally, 2014 in the Chinese Year of the Horse.  What does that mean for plant lovers?  How about planting a horse chestnut in your garden?  Horse chestnut (Aesculus hippocastanum) is a large tree native to the Balkans that has palmately compound leaves and very showy flowers born in upright panicles.  Our native Aesculus is Aesculus parviflora (alright its common name is bottlebrush buckeye-so connecting this plant to the year of the horse is a stretch) and it is a wonderful, summer-flowering shrub that forms a large mounding colony.  It is quite showy in bloom or in fall color.
