RE: Vinca - colour for a hot spot.
Excellent selection of plants always! I have seen these plants thrive amazingly in Karachi, Pakistan. The flowers can be seen most of the year.
Abundant blooms and ease of care make vinca (Catharanthus roseus) an excellent selection if you have little time to tend your garden.
Useful in borders, flowerbeds, rock gardens and containers, the vinca flower provides instant color wherever it grows. The round, flat blooms appear on top of 12- to 15-inch stems.
These drought-tolerant bedding plants thrive in any soil type as long as it is fast draining and not overly fertile. Hardy in U.S. Department of Agriculture plant hardiness zones 9b through 11, vincas thrive in full sun and require temperatures no colder than 60 degrees Fahrenheit.
Although vincas are known as summer-flowering annuals, they are actually biennials and will flower for you all through autumn into winter. Prune back by 50 per cent at the beginning of spring, liquid fertilise and they will start flowering again at the end of spring.
The cascading varieties of the Cora Cascade vinca include Polka Dot, with a profusion of soft pink single flowers with a red centre. Other colours include lilac, magenta, cherry and strawberry.
They are also available as deep red, purple/black and pure white-flowering plants.
