Maybe you call these plants Peace lilies most likely due
to the white flag-like flower portions properly called a
spathe. These white modified leaves surround the true
flowers and are probably why the plants have both the
scientific and common names spathiphyllum. Well, they are
on parade in my landscape flowering freely.
landscape is where they stay most of the year growing in
containers. Some over the years have been willing to take
a chance and grow them in the ground. But where I live it
can get cold and the plants are often damaged by
temperatures of freezing and below. This year the plants
are spectacular. Most likely it is due to the mild winter
where there was minimal plant damage as many did get left
outdoors during the cold. If it gets really cold, some are
protected in a small green house but others have to fend
for themselves under covers in the warmest spots of the

Late winter and spring are the normal flowering
times for spathiphyllum as they are affected by day
length. This is when you can see the most blooms but they
do flowers sporadically throughout the year too. The
plants fill with the white spathes for weeks of shade
My plants grow in heavy to
light shade. They burn in full sun and turn very yellow.
When flowering is over it is division time. Most fill
their containers very quickly during the warmer months.
Don’t feel bad about taking a knife to cutting the plants
in halves or in quarters and giving each a new container.
Then I add a slow release fertilizer like Osmocote or
Miracle-Gro Shake’n Feed to supply nutrients for 3 to 4
months at which time they get another feeding. Do keep the
soil moist as spathiphyllum like a damp soil.
concern I get mail about is the white spathes turning
green over time. You have to remember these are modified
leaf portions and many eventually develop chlorophyll and
turn green. You can enjoy them or just cut them off.
By the way, this is a great house plant too. It grows
in the lower light areas but needs bright light to flower.
