White Roses With Orange Tips

Climate

• Rose flower colors are not influenced by soil pH like hydrangeas. With roses, the flower color is influenced by climate and sun exposure. Roses grown in hot climates commonly have different bloom colors from those grown in cooler climates. An orange blend may look more like a red blend in cool climates, whereas in hot climates, it may look closer to apricot or salmon. Spring roses in hot climates will also have more pronounced coloration than roses produced by the same shrub in the summer. How much difference there is in the bloom color varies depending on the cultivar.

Sunlight

• The amount of direct sunlight a rose gets will also influence bloom color. While most roses require at least four to six hours of direct sunlight each day, too much direct sunlight can result in less orange coloration on the flower petals. The orange petal tips may just become more pale or may turn a different color altogether. In very hot climates, rose shrubs that receive a few hours of direct sunlight in the morning and late evening will produce flowers with darker, more pronounced coloration. Roses grown in direct sunlight all day and those that receive direct hot afternoon sun will have less or different coloration.

  Rose flower colors can also change as the flower buds open and age. This is a naturally occurring color change that will happen regardless of climate and sun exposure. How much the bloom color changes or fades, however, can be influenced by climate and sunlight.

Hybrid Teas

• "Imperatrice Farah" is a hybrid tea rose that is listed as salmon and white or red and white. It is also known as "Empress Farah Strawberry Parfait." The flower color is influenced by climate and the age of the flower. When the shrub is in full bloom, there is so much variance in bloom color it can appear to be more than one rose bush. The new flower buds are white with a slight green tint. As the flowers open, the petals stay white or slightly cream or tan at the center. The tips become salmon, coral, orange, dark burnt orange, pinkish red or deep velvety red. The color that does appear at the tips of the petals becomes darker as the blooms age.

  "Gemini" is a hybrid tea with less variation in bloom color than "Imperatrice Farah." It is referred to as a coral or pink blend. The flower petals are white or cream at the center with orange, coral, pink or raspberry edges. The petal edges tend to be more red in cooler climates and coral to orange in hotter climates.

Miniature

• "Arcanum" is a miniature rose with apricot blend blooms. The flower petals can be creamy white or bright white at the center. Petal tip colors can be deep apricot, brownish-orange, orange-red or red. The tip color can be a narrow band just around the very edge of the petal or it can cover the entire outer edge of the petal and blend into the center.
