Landscape Attributes

Blue Finger is an herbaceous annual with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This is a relatively low maintenance plant, and usually looks its best without pruning, although it will tolerate pruning. It has no significant negative characteristics.

Blue Finger is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • Rock/Alpine Gardens
  • General Garden Use
  • Container Planting

Planting & Growing

Blue Finger will grow to be about 18 inches tall at maturity, with a spread of 24 inches. Although it's not a true annual, this plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

This plant does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America.

Blue Finger is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers and foliage against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.

What Our Clients & Customers Say

To Marc and the crew at Wagner Landscaping,
Just short note to thank you for the quality craftsmanship you delivered at our Jefferson City residence. Our home was cut into a steeply sloping lot necessitating the need for considerable water management and erosion control landscaping. The sculpturing, erosion matting, retaining wall and ditch work was completed in short order, getting us ready for the winter. We are confident that when the snow melts and the rainy season comes next year our property will be ready to handle it. Thanks and best wishes to all.

– Steve Wilhoit –

Dear Chris,
I hope this is the greatest letter of recommendation you’ve ever received – I know it won’t be your last. To anyone who reads this, I can say without hesitation that Chris Wagner should legally change his name to Mr. Boulder! (Just one look at his hands will confirm that this title has been earned.) Chris and his team tackled a very remote project for us with hustle, integrity, imagination and great execution. We couldn’t be happier with the results. If Chris says “it” – “it” happens! We are happy to enthusiastically recommend one of the finest individuals with whom we have worked.
Sincerely,
William W. Nicholson
