Mandevilla "Red Velvet" is a tropical vining plant that produces large 5-6 flowers that are red when it's hot (85F) and pink when its cool. In the heat of the late spring and summer the blooms turn a beautiful soft reddish color. As the name implies, the blooms look like red velvet. In the early spring, with cooler temperatures the blooms are various shades of pink, then as temperatures warm to the mid 80s F the flowers began to turn bright red. The flowers last for about 5 days. They open pink and turn red as they mature. Since flower color is affected by temperature, light and humidity it is not known for sure that the bright red color will appear in all areas that the plant is grown. The color in Florida is bright red under Florida conditions when temperatures are in the 80s F. Each flower stem will last months and may produce as many as 60 blooms with 3-5 blooms open at one time. Once in flower the plant will flower constantly, producing many flower stems. Its peak flowering season is March through November but may bloom year round if grown in evenly warm temperatures. It grows best in full sun conditions with moist soil and a medium rate of fertilizer. Blooms appear approximately 10-12 weeks after pinching. Mandevilla “Red Velvet” is ideal for trellised containers or hanging baskets. “Red Velvet” is very vigorous and grows faster and stronger than most other Mandevilla.
|Cultural Code||TGH HP|
Some of you grow only indoors, some only in terrariums; many of you have hobby greenhouses; while a growing number of customers live in subtropical or tropical areas of the world. These brief codes are an attempt to suggest whether or not a particular plant will do well in your particular conditions.
If an entry has the cluster HP CGH, this means normal house plant culture will be successful if the plant is given a cool CGH moist location; however if the entry has the cluster CGH HP, you would interpret this to suggest that while Cool Greenhouse conditions are needed for total success with this plant, House Plant conditions will be adequate, while not ideal. If the cluster is HH CGH you would interpret this to mean that while in Zone 8 or below this will be winter hardy outdoor, further north it will need considerable mulch, a cold frame, or a Cool Greenhouse to thrive. And so on.×
