When to cut Liatris
Steve Castleberry
We planted six liatris two years ago and have six tall spikes about 24
inches tall. One is beginning to turn purple from the top down- about
two inches from the top. How far down the spike to we let the color come
before cutting and bringing inside for arrangements. Will the color
continue to develop after being cut and put in water? Thanks in advance
for your help.

Once the needles have emerged about 1/2" to 1". The flower should last for
2 to 3 weeks inside. Just remember to change the water every 2 or 3 days.

I'm in Ann Arbor, MI; yes, in good years we get some yellow coloration
but in most years we get at least as much brown as yellow. It's a really
exceptional year when the ashes provide much of an autumn show (and it's
the most common street tree in my neighborhood so I see a lot of them).
I think they're green ash (they're city-planted street trees); perhaps
the leaf fungus they get every year is dulling the amount of color the
leaves attain--disease-free leaves might be brighter. However, I still
don't think there are any ash trees that produce red or bright orange
fall color, which is what the poster was asking about.

Sorry to re-post this, but my newsreader is acting weird and posted it
before under the wrong heading.

Oh, yes, Susan, Ann Arbor has lots of the white ashes that John Woodworth
mentions above. They're widely planted and do produce the yellow, maroon, and
purple coloration in the fall. Many of them were planted as street trees in
the northwest quadrant of town, where I lived. Interestingly, if a leaf is
partially shaded by another leaf, it will show yellow on the shaded part and
maroon or purple on the sunlit part. The green ashes just turn yellow (or maybe
not even that), as you say.
