Abstract

A new and distinct selection of Ninebark, Physocarpus opulifolius, which shall be referred to hereinafter as cultivar `Monlo`. Cultivar `Monlo` differs distinctively from other Physocarpus opulifolius plants by possessing a unique combination of an outstanding cold hardy shrub with intense foliage color throughout the seasons peaking in summer to a maroon red and contrasting to the creamy-white flowers.

Description

BACKGROUND OF THE INVENTION
This invention relates to a new and distinct selection of Physocarpus opulifolius, a member of the Rosaceae family. We discovered the new selection, cultivar `Monlo` as a seedling in June 1968 from a field of 120,000 other seedlings. The discovery was based on the red foliage this one particular seedling exhibited in this large field planting of all typically green foliaged plants in Ellerbek, Schleswig-Holstein, near Hamburg in Germany.
The new plant has been asexually reproduced by cuttings at Kordes Jungpflanzen, Muhlenweg 8, Bilsen in Germany and recently at Monrovia Nursery, 18331 East Foothill Boulevard, Azusa, Calif.
The discovery substantially differs by the unique characteristic of red foliage which sets the claimed plant apart from other Physocarpus opulifolius plants and cultivars which I am aware. Had the initial seedling not been successfully sown and discovered it may have been lost to mankind. It is unlikely the favorable attributes of this plant could be conveyed to progeny through sexual reproduction. However, through extensive asexual propagation by rooting cuttings of this plant it has been established that the novel, exceptional characteristics are stable and reliably passed on to clonal specimens.
SUMMARY OF THE INVENTION
To my knowledge, Physocarpus opulifolius cultivar `Monlo` is the only red foliaged Ninebark. Ninebarks typically exhibit green foliage. There do exist some selections which have a yellow to yellow green foliage. My selection changes seasonally and after winter dormancy the first foliage to emerge in spring is dark red, summer foliage matures to a maroon dark red and autumn foliage changes to a dark brown red. This spectacular red seasonal foliage color of my selection adds an attribute to a widely used landscape pant.
Ninebarks are grown as background foliage shrubs. They are remarkably free from pest and diseases and their adaptation to different soil types and shade or sun and cold temperatures make this a versatile landscape addition. Pruning and shearing are easily tolerated. Plants which are not sheared exhibit a lovely natural growth habit. Winter is the dormant season with branches free from foliage exhibiting a exfoliating bark.
Typically white to pinkish clusters of flowers appear in late spring to early summer on Physocarpus opulifolius. My cultivar `Monlo` has a cream white flower color which contrasts beautifully with the red foliage.
BRIEF DESCRIPTION OF DRAWINGS
The illustration of the discovery shows the maroon reddish summer foliage. Displayed in a corner inset is an inflorescence in full bloom contrasting with the maroon reddish foliage.
The other illustration displays the overall growth habit.
