For those not familiar with the perennial of the year program, it was begun in 1990 by The Perennial Plant Association, a group of professionals within the horticultural field whose common goal is to promote the use of perennials. Every year, these members elect a plant they feel best encompasses the following criteria: offers multiple seasons of garden interest, requires minimal maintenance, is easily propagated and can be cultivated successfully over numerous climate zones. Just remember, the award has existed only since 1990, so there are still many that are deserving and yet to be crowned. If you are looking to begin a perennial garden or fill in a gap, here’s a perfect place to start:

| Panicum virgatum 'North Wind' |
|
| 2014 Perennial Plant of the Year - Panicum virgatum 'North Wind'
Panicum virgatum ‘Northwind’ takes the spotlight as the 2014 Perennial Plant of the Year™ awarded by the Perennial Plant Association©. Roy Diblik of Northwind Perennial Farm introduced Panicum virgatum ‘Northwind’ in the early 1990s. It came from seed he collected in 1982 near railroad tracks off of Highway 25 in South Elgin, Illinois. As the seedlings grew, Roy noticed one unusual plant growing upright, rather than arching, with beautiful blue-green leaves. Roy says this about his find: “I think the habit of this plant with its distinct upright growth habit, its durable lifestyle, and appreciated architectural essence has helped it find a welcomed place in many gardens. This is one of uncountable naturally occurring hybrids that occur with all native plants…we just need to keep our eyes open.”

| Baptisia australis |

2010 Perennial Plant of the Year - Baptisia australis.

It makes a terrificbackdrop for other perennials and groundcovers growing at its feet.
Baptisia australis is very easy to grow and requires little maintenance if sited properly. It grows best in full sun, but will tolerate light shade. Once established, Baptisia is drought tolerant due to its tough, deep tap root. No serious pests or diseases are known to afflict this plant.
