Abstract

A new and distinct Hybrid Tea rose plant is provided which forms attractive blossoms that are hot pink in coloration. The new variety is a spontaneous mutation of unknown causation of the ‘Meilavio’ variety (U.S. Plant Pat. No. 10,845) that forms vivid red blossoms. The blossoms are fully double, long lasting, and very quartered in the sense the petals of the fully opened blossoms tend to be arranged in a plurality of zones when viewed from above. The vegetation is strong and vigorous and the growth habit is erect. Many large thorns are exhibited. The foliage is very decorative, dark green, and semi-glossy and contrasts nicely with the hot pink blossom coloration. Good resistance to Black Spot and Powdery Mildew is displayed. The new variety is well suited for providing attractive ornamentation in the garden.
