Abstract

A distinct cultivar of Perovskia plant named `Little Spire`, characterized by its upright and relatively compact plant habit; relatively short flower stems; small dark purple blue flowers; numerous flowers per plant; and excellent garden performance.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Perovskia plant, botanically known as Perovskia hybrida, and hereinafter referred to by the cultivar name Little Spire.
The new Perovskia was discovered by the Inventor in Rijpwetering, The Netherlands, in 1995 in a seed bed of sown Perovskia hybrida seed from various crosses of unidentified Perovskia seedling selections.
Asexual reproduction of the new cultivar by terminal cuttings taken at Rijpwetering, The Netherlands, has shown that the unique features of this new Perovskia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Little Spire have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Little Spire`. These characteristics in combination distinguish `Little Spire` as a new and distinct cultivar:
1. Upright and relatively compact plant habit with relatively short flower stems.
2. Small dark purple blue flowers.
3. Freely flowering with numerous flowers per plant.
4. Excellent garden performance; good weather tolerance.
Plants of the cultivar Little Spire can be compared to plants of the nonpatented Perovskia atriplicifolia cultivar Blue Spire. However in side-by-side comparisons conducted in Rijpwetering, The Netherlands, plants of the cultivar Little Spire differ from plants of the cultivar Blue Spire in the following characteristics:
1. Plants of the new Perovskia are more compact than of plants of the cultivar Blue Spire.
2. Leaves of plants of the new Perovskia appear slightly grayer, are less deeply serrate and more acuminate than leaves of plants of the cultivar Blue Spire.
3. Plants of the new Perovskia have shorter flower stems than plants of the cultivar Blue Spire.
4. Plants of the new Perovskia have darker purple blue flower color than plants of the cultivar Blue Spire.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a side perspective view of a typical plant of the new Perovskia in outdoor cultivation. Flower and foliage colors in the photograph may appear different than the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
