Know before you buy

Since each plant has a mature spread of approximately 24 inches, you should space them about 2 feet apart to allow them to fill in effectively without overcrowding.
No, it is considered waterwise and drought-tolerant once established. While it needs moderate watering initially to settle in, it prefers well-drained soil and does not like to sit in waterlogged conditions.
Yes, its trailing growth habit makes it an excellent choice for containers, hanging baskets, or rock gardens. Ensure the container has adequate drainage to keep the soil from staying too wet.
This plant performs best in full sun to partial shade. Providing at least a half-day of direct sunlight will ensure the most abundant display of lavender-blue, star-shaped blooms.
