The only downside is that the lawn with the crocus leaves cannot be cut for
a minimum of 42 days after flowering has finished~~ as with all bulbous
plants, even if still green~ surprisingly.
They will not increase more than you wish and certainly will not get out of
control. The clumps will just thicken and become more floriferous. Similar
to daffodils.
A general guide for all similar planting is at 2 or 3 the times their
own size. This generally holds for seeds also.
Best Wishes.

Hi there. While out walking yesterday my husband and I passed by a lawn
that was full of crocus flowers and we just loved it. I was just
wondering.
Are there any downfalls to planting these little bulbs in your lawn? Do
they spread like the dickens and we'd eventually have only crocuses? It
just looked so nice and so colorful for the brown-lawn time of year so I
had
to ask. Also, if we decide to plant these little bulbs next fall so that
we
can have a lawn like this, how deep do you plant them? I visited a number
of websites but nobody said how deep to put the bulbs. Thanks for your
help!
