Spiderwort
Morning-blue three-petaled flowers on a plant that's nearly indestructible. Honest caveat: it reseeds everywhere. Wilder gardens only.
Three-petaled blue and purple flowers that open each morning, on an easy, forgiving native.
Why it works here
Spiderwort is about as easy and forgiving as a native gets, which is why I like it for people just starting with native beds. The blue to purple three-petaled flowers open in the morning and close by afternoon heat, then a fresh set opens the next day over a long spring-to-fall run, and native bees love them. It grows statewide and shrugs off a wide range of soil and moisture, from a spot that occasionally floods to one that dries out. I use it as a filler in sunny to part-shade beds where I want dependable color and do not want to fuss.
Care
Plant it in full to part sun in just about any soil, it is not picky. Water to establish, then it handles both wet and dry stretches. Here is the honest part: it spreads and reseeds readily, so it can move around the bed. If it gets floppy or tired-looking in summer heat, cut it back hard, even to a few inches, and it flushes fresh new growth and more flowers. Pull the seedlings you do not want once or twice a year. Compost and mulch, no synthetic feed needed.
Common problems
Spreads quickly: the real caveat. It self-seeds and expands, so it can outrun its spot. Cut it back and pull volunteers to keep it in bounds, it is easy to control, just not tidy on its own.
Floppy in heat: normal. Shear it back hard midsummer and it comes back clean.
Otherwise trouble-free, no meaningful pest or disease problems.
Common questions
Why are the flowers closed by the afternoon?
That is normal. Each flower opens in the morning and closes with the afternoon heat, but a new batch opens the next day, so the show keeps going for months.
Will it spread too much?
It can. It seeds and expands, so plan to pull volunteers a couple times a year. It pulls easily, so it is manageable, just not a stay-put plant.
It looks ragged in summer, what do I do?
Cut it back hard, even to a few inches. It bounces right back with fresh leaves and a new round of flowers.
