Big Leaf Vinca

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.

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 full to partial-shade locations.
• Mulch with common mulch materials in dry Western climates. Leave un-mulched in moister Eastern climates.
• Water regularly during 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 the foliage is looking chlorotic (yellow). Vinca major needs only a light fall application of Yum Yum Mix or nothing at all if growing well.

Special comments:

• Vinca major is an indestructible evergreen groundcover that is invaluable for planting in dry shade under trees. But it is an aggressive grower that should not be planted with other small growing perennials as it will smother them. It is best placed under larger growing shrubs and trees.
