USPP21031P3 - Punica granatum plant named ‘PIIPG-I’ - Google Patents

Abstract

A new and distinct cultivar of Punica granatum plant named ‘PIIPG-I’, characterized by its compact, upright spreading growth habit, lustrous, dark green foliage, reddish-orange flowers, maroon-purple fruits, and cold hardiness to USDA Hardiness Zone 7.

Description

Genus and species of plant claimed: Punica granatum L.

Variety denomination: ‘PIIPG-I’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Punica granatum, a member of the Punicaceae family, hereinafter referred to by its cultivar name ‘PIIPG-I’. This cultivar is grown primarily as an ornamental for landscape use and for use as a potted plant.

The cultivar originated from open-pollination of Punica granatum ‘Nana’ (unpatented) in Watkinsville, Ga., and was selected from the progeny seedlings of this pollination by continued evaluation for fruit color and growth habit, and improved leaf and flower characteristics.

‘PIIPG-I’ has been asexually reproduced by softwood cuttings in Watkinsville, Ga. The characteristics of the cultivar have been stable and reproduced true-to-type in successive vegetative generations.

SUMMARY OF THE INVENTION

‘PIIPG-I’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been observed and represent the characteristics of the new cultivar. In combination these characteristics distinguish ‘PIIPG-I’ from all other varieties in commerce known to the inventor. 1) Compact, upright spreading growth habit. 2) Small, lustrous, dark green foliage. 3) Reddish-orange flowers. 4) Maroon-purple fruits. 5) Cold hardiness to USDA Hardiness Zone 7.

‘PIIPG-I’ is distinguished from its female parent ‘Nana’ by its vigor, growth habit, flower color, fruit color, and quantity of flowers and fruit produced. ‘PIIPG-I’ has a more vigorous, upright spreading growth habit, whereas ‘Nana’ has a less vigorous rounded growth habit. ‘PIIPG-I’ has reddish-orange flowers and maroon-purple fruits, whereas ‘Nana’ has orange flowers and tan to red-orange fruits. ‘PIIPG-I’ flowers and fruits more prolifically than ‘Nana’. There are no other cultivars of Punica granatum with this combination of characteristics known to the inventor.

Plants of the new Punica can be compared to plants of the cultivar ‘Eight Ball’ (unpatented), which has similar colored flowers and fruits. However, in side-by-side comparisons conducted in Watkinsville, Ga., plants of the new Punica differed from plants of the cultivar ‘Eight Ball’ in the following characteristics: 1. Plants of the new Punica had a smaller foliage, flowers, and fruits than plants of the cultivar ‘Eight Ball’; 2. Plants of the new Punica had a smaller and more compact growth habit reaching only about half the size of plants of the cultivar ‘Eight Ball’ in the same amount of time
