  The Latin word of the week  

Bonariensis is an example of a species name or epithet that identifies the plant's native area. This case, the name refers to Buenos Aires, a large province of Argentina and home to the city of Buenos Aires, established by Spanish settlers in the early 1500s as a trading city. The current capital of the province is La Plata, founded in the late 1800s.

Several different plants share this epithet, but the one that most often springs to mind is a tall, perennial species of Verbena commonly known as "purpletop".

This particular plant was discovered in the 1700s and named by Linnaeus. It recently caught the attention of the gardening world when some intrepid gardeners realized its airy growth could be used to create an interesting "screen" effect. Placed in front of other plants, the delicate flowers allow the background plants to peek through for a charming effect.

  The Plant of the Week  
Columbine 'Winky Blue and White'
Aquilegia vulgaris

Columbines (Aquililegia vulgaris) are a well loved garden flower. The Winky series is a group of cultivars that produce upward facing flowers. Winky Blue and White is very popular with its deep blue and white bi-tone flowers. There is also a Double Winky Blue and White for those that prefer a fuller flower.

Plant your columbines in an area that receives sun to partial shade. Your location determines how much sun your columbines can tolerate. In parts of the country where summers are especially hot and humid, columbines appreciate more shade than an area that has cooler summers with more cloudy days.

Columbines, classified as a perennial plant, return from the same roots year after year. How long that they live will be determined by how ideal the conditions are. Gardeners in the parts of the world that experience cooler summers have columbines with a longer life span than those in the hotter regions.

Columbines grow successfully in most of North America. The exceptions are the desert Southwest and Florida.They prefer moist, well-drained soil with lots of organic matter.
