Years ago I planted my first Marshmallow seeds when
my Hollyhock infatuation started. All this time later, the
plants have produced well and have grown quite large.

I recently cut all the dead foliage back to the ground just
in time, as spring is here and the marshmallow is more
than willing to come up once again.

A very pleasant plant to have in the garden. The bees
just love coming for a visit!

The original MARSHMALLOW was made in Egypt over 3,000 years ago. The pulp of the root was mixed with honey to create a candy.
