X plant named ‘Eye Spy’

- Walters Gardens, Inc.

The new hybrid X Heucherella plant named ‘Eye Spy’ with moderately cleft palmately lobed foliage having acute apices and variable coloration starting in the spring as amber yellow-colored with dark rose centers, transitioning to bright chartreuse green with slight silver overlay and burgundy surrounding the veins. ‘Eye Spy’ produces a pink flower effect from fine white petals, pink calyces and deep rose buds beginning in late spring. Habit is low mounded and winter-hardy plants are able to withstand more heat and sun than typical X Heucherella cultivars.

Description

Botanical denomination: X Heucherella (Heuchera x Tiarella).

Cultivar designation: ‘Eye Spy’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct intergeneric hybrid between Coral Bells and Foam Flower, both in the Saxifragaceae family and given the cultivar name of ‘Eye Spy’ with the combined generic epithet X Heucherella. X Heucherella ‘Eye Spy’ resulted from an intentional cross between the unreleased proprietary Heuchera hybrid known by the breeder code 12-62-03 (not patented) as the female or seed parent and the unreleased proprietary Tiarella hybrid known by the breeder code 11-14-08 as the male or pollen parent. The new plant was hybridized by Hans A. Hansen at a wholesale perennial nursery in Zeeland, Mich., USA on Jan. 31, 2013 and seeds from the cross harvested in the spring of 2013. The new plant passed the original evaluation in summer 2013 and was given the breeder code of 13-99-9 in the spring of 2014 through the subsequent years of further evaluations. The new plant was selected from among many other crosses and X Heucherella seedlings growing at the same nursery in Zeeland, Mich. which met the rigorous criteria of excellent foliage and habit established as breeding goals. X Heucherella ‘Eye Spy’ has been asexually propagated since 2014 by division of the rhizome at a nursery in Zeeland, Mich. and also by careful shoot tissue culture propagation. The resultant asexually propagated plants have remained stable and exhibit the same characteristics as the original plant.

No plants of X Heucherella ‘Eye Spy’ have been disclosed or sold, under this or any name, in this country or anywhere in the world, prior to the filing of this application, with the exception of that which may have been disclosed within one year of the filing of this application and was either derived directly or indirectly from the inventor.

BRIEF SUMMARY OF THE INVENTION

X Heucherella ‘Eye Spy’ differs from its parents as well as all other X Heucherella known to the applicant. Compared with the female parent with coral red flowers with deep rose buds, the new plant has light pink flowers with light rose buds. The foliage of the female parent is less dissected with rounded apices, has a general burgundy color with silver overlay. The male parent has a chartreuse to light green leaf margin and the flowers are near white compared with the new plant. The most similar cultivars include: X Heucherella ‘Alabama Sunrise’ U.S. Plant Pat. No. 19,611 and ‘Stoplight’ U.S. Plant Pat. No. 16,835.

Compared with the new plant, ‘Stoplight’ has shallower cleft foliage with more rounded lobes and the flowers and buds are not as pink and rose-colored respectively. Compared with the new plant, ‘Alabama Sunrise’ has more deeply cleft foliage with thinner burgundy coloration surrounding the veins and the flowers and buds are white

The new plant differs from all Heuchera, X Heucherella and Tiarella known to the inventor in the following combined traits:

    • 1. The foliage color of X Heucherella ‘Eye Spy’ is variable with the seasons starting in the spring as an amber yellow-colored with dark rose centers.
    • 2. Leaves transition to bright chartreuse green with slight silver overlay and burgundy surrounding the veins.
    • 3. The leaf blade shape is moderately cleft with sharp lobes tips.
    • 4. The flower petals are near-white with pink calyces and deep rose buds, tightly arranged on panicles just over the foliage in late spring.
    • 5. Habit is low mounded with multiple tightly clustered shoots emerging at the base all season.
    • 6. The plant is robust, seedless, compact and is more heat and sun tolerant than typical X Heucherella.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of ‘Eye Spy’ including the unique traits. The plant in the photograph is of a two-year old plant grown in a double-poly coated greenhouse without further shading, with supplemental fertilizer and water as needed at a wholesale perennial nursery in Zeeland, Mich., USA. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.

FIG. 2 shows a close-up of the flowers and buds.

DETAILED BOTANICAL DESCRIPTION

The following description is based on two-year-old and three-year-old plants growing in double poly greenhouse with supplemental water and fertilizer at a wholesale perennial nursery in Zeeland, Mich., USA.
