| Abstract: |
A new and distinct form of Ajuga reptans plant characterized by its unique foliage coloration and markings. Mature leaves are colored gold to cream on the margin with shades of gray green in the center. New leaves show brown and khaki shades. It has a dwarf habit, small, narrow leaves, and blue flowers on ten centimeter spikes. |
| Claim: |
I claim:
1. A new and distinct form of Ajuga plant substantially as shown and described. |
| Description: |
Botanical Denomination: Ajuga reptans.
Variety Designation: `Toffee Chip`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Ajuga reptans, given the name, `Toffee Chip`. Ajuga is in the family Lamiaceae. This plant originated from a naturally occurring meristematic mutation of Ajuga `Chocolate Chip` (anunpatented plant with the synonym `Valfredda`). The mutated plant was found in a garden at an Oregon nursery.
This plant is unique in its foliage coloration and markings. Mature leaves are colored gold to cream on the margin with shades of gray green in the center. New leaves show brown and khaki shades. `Toffee Chip` has the same great attributes ofits parent, the dwarf habit, the small, narrow leaves and blue flowers on ten centimeter spikes.
The new variety has been reproduced only by asexual propagation (division and micropropagation). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and micropropagation as done inCanby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. Thephenotype may vary with variations in environment without a change in the genotype of the plant.
BRIEF DESCRIPTION OF THE DRAWING
The drawing shows a two-year-old Ajuga `Toffee Chip` growing in the garden in fall in Canby, Oreg.

Corolla description.--1 cm long and spreads to 4.5 mm wide, tube and throat 5 mm long and 1 mm to 1.5 mm wide, 2 small upper lobes less than 1 mm long and wide, acute, three lower lobes, twospreading sideways, the terminal lobe two lobed and obovate, entire, glabrous inside, villous outside, color inside Violet Blue 94B, outside Violet Blue 91A.
