Features and Growing Tips
Note: Each live plant is unique and may differ from the photo while maintaining its beauty. Plants come in a plastic pot; other items in images are not included.
Landscape Qualities
True Blue Gentian is an herbaceous perennial with a mounded form. Its medium texture blends into the garden | but can always be balanced by a couple of finer or coarser plants for an effective composition.
Ornamental Qualities
True Blue Gentian features dainty clusters of royal blue tubular flowers with white throats at the ends of the stems from mid summer to early fall that fade to lavender over time. Its pointy leaves remain green in color throughout the season.
Planting and Growing
True Blue Gentian will grow to be about 30 inches tall at maturity | with a spread of 18 inches. When grown in masses or used as a bedding plant | individual plants should be spaced approximately 14 inches apart. Its foliage tends to remain dense right to the ground | not requiring facer plants in front. It grows at a medium rate | and under ideal conditions can be expected to live for approximately 15 years. As an herbaceous perennial | this plant will usually die back to the crown each winter | and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
This plant does best in full sun to partial shade. It does best in average to evenly moist conditions | but will not tolerate standing water. It is very fussy about its soil conditions and must have rich | acidic soils to ensure success | and is subject to chlorosis (yellowing) of the foliage in alkaline soils. It is quite intolerant of urban pollution | therefore inner city or urban streetside plantings are best avoided | and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. This particular variety is an interspecific hybrid.
