Vinca major flower plant

Vinca (Vinca) is a genus of plants native to the Old World and Asia. Annual Vinca (formerly known as Vinca rosea) is now considered to be in a separate genus. They are used respectively to stimulate the brain and as a vasodilator, and to reduce high blood pressure. A semi-synthetic alkaloid originated from Vinca, vinorelbine, is used to reduce tumor growth rates, with a higher response rate when used in ovarian cancer, sarcoma, non-small-cell lung cancer, and bladder cancer.

Preferred growing conditions:

• Plant Vinca minor in compost enriched, acidic loam. Vinca major will grow in any soil type including clay. Both are best positioned in a full to partial shade locations.
• Mulch with common mulch materials in dry Western climates. Leave un-mulched in moister Eastern climates.
• Water regularly the first growing season to establish the plant. Vinca minor appreciates regular irrigation in arid climates. Vinca major is xeric and only needs occasional deep watering. Rainfall is generally sufficient for both species in moist Eastern climates.
• Deadheading the plants is not necessary.
• Fertilize Vinca minor lightly in the fall with a half and half mix of Yum Yum Mix and good quality compost. Supplement that with the addition of soil sulfur if foliage is looking chlorotic (yellow). Vinca major needs only a light fall application of Yum Yum Mix or nothing at all if growing well.
