Reseeding, if the forget-me-nots in question are Myosotis species.

What kind of forget me nots do you have?

it is a myosotis specise

Those are hardy perennials, but not known for living many years per individual plant. Ones I started from spring, then moved, are back this year. And a few seedlings, not a ton, a nice amount that I like but I did do some deadheading once in a while, not very dedicated about it for this plant. Might have been more seedlings without that.

Forgot to add, if memory serves, they behaved similarly in OH (5b.)

in z5 MI they are a true biennial....

ken

I thought so. They are so lovely

I agree! Took this pic. Sunday. They're cute with Oxalis at the moment.

I grew them from seed here in WI and they multiplied and returned for about 4 years. My assumption was that they were a short lived perennial. I need to start dome more, they are sweet.

They are one of the 8 wonders of the wolrld

There are 2 kinds of forget-me-nots. Perennial and annual. The perennials are shorter(about 8 inches) and have a smaller blossom and bloom in early summer. The annual are taller(12 to 14 inches) but they peter out when the hot weather hits. They are prolific seeders and once planted you can be sure they will be back as long as the mulch is removed so they can touch the ground.

As a side note--you'll know if they are forget-me-not seeds if they are stuck to your gardening gloves when you pull the plants. The plants way of spreading it's seeds is to give them little burrs.

Mines is probally the annual. I believe mines could be possibly a perrenial

Myosotis sylvatica is the one usually sold in seed packs, which is reported as a perennial some places, as a biennial on other sources. But there are many more than 2 Myosotis, some definitely annuals. Probably where lot of the the confusion comes from, and the fact that it's not always possible to look at a patch and know if individuals are starting their 2nd or 3rd year. If a biennial plant is prevented from setting seed, it may come back.

There's also Bunnera macrophylla, if anyone's interested, though definitely not an annual.

Sounds like there is conflicting information in different sources. Whatever they are i love them
