Earlier this year, I purchased 6 of Monrovia's Weigela florida 'Red Price' (Red Prince Weigela) based in part on the description in the catalog that the flowers are "nonfading rich red flowers against dark green leaves". However, the flowers are magenta in color and the leaves are not dark green.
Will the color of the flower become deeper red as the shrub ages? What factors determine its flower color?
|The leaf and flower color on your Red Prince Weigela should be as described in the catalog. Some factors affecting leaf and flower color include transplant shock (a temporary condition that will right itself once the roots become established), soil that's highly acidic or alkaline (extremes on the pH scale can bind up nutrients, making them unavailable to plant roots), or lack of proper exposure to sunshine. Weigela grows best in full sunshine to light shade, in soil that's neutral to slightly acidic. The plants will adapt to most garden soil, as long as it's rich, moist and well draining. If your plants have been in the ground for a month or two and are producing new growth, you can lightly feed them with an all-purpose garden fertilizer, applied as recommended on the label. The fertilizer should help the leaves green up, and the flower color may perk up as well, as your plants receive the nutrients they require. Best wishes with your shrubs!|
