Year-round
Bluets are tiny, low-care plants that like sun to part shade and little competition.
- They take full sun, part shade, or dappled light, in loam, sand, or rocky soil with good drainage.
- They stay 3 to 6 inches tall and wide, so give them a bare patch, a path edge, or a lawn spot with little competition.
- Rated low maintenance, with no serious insect or disease problems reported.
- Plants seed out and form colonies, which is how you get a bigger patch.
A low, edged patch along a path reads as intentional rather than a lawn gap.
Fall
Fall is quiet, with seed and division as the only jobs.
- Plants spread by seed, so leave bare gaps open if you want colonies to fill in.
- Division is another way to propagate, if you want to move a clump.
Winter
Winter needs nothing from you, since this plant is hardy to a cold zone.
- It is listed hardy in USDA zones 3 to 9, so no winter protection is called for.
- Low maintenance, so there is no cutting back task.
Spring
Spring is bloom and transplant time.
- Blooms come in spring and summer, and one plant's bloom lasts about three weeks in late spring.
- Spring rosettes can be transplanted, and clumps can be divided.
- Seed-grown plants flower in their second year.
Summer
In summer, bluets need little beyond keeping rivals from crowding them out.
- They tolerate average, dry, or wet soil and are listed as drought tolerant.
- Keep taller plants and thick weeds from crowding the low clumps.
- Rated low maintenance, so there is no regular summer task.
