CULTURE REPORT
FINISHED PRODUCTION
'Silver Swirl' is suitable for quart containers all the way
up to 1.5 gallon. Finishing time will be directly related to
temperature - the warmer the better. 'Silver Swirl'
will not mind it HOT. However, temperatures below
62° F/16° C will increase the finish time.
In general, with a 68° F/20° C average daily
temperature, I would expect 8 weeks to finish a quart,
12 weeks for gallons, and 14+ weeks for 1.5 gallon.
Transplant one plant per pot into a well-drained media.
Again, do not allow the media to remain saturated for
extended periods of time. Outdoor production in the
South is ideal, but chances of flooding rains can be an
issue. For indoor production in the North, provide the
highest light and temperatures possible. In either region,
no PGR will be needed.
Controlled release fertilizer at medium to high rate
can be beneficial. Additionally, liquid feed may be
applied as necessary. 'Silver Swirl' is not particularly
salt sensitive but be aware of excessively high EC while
growing the plants dry.
As far as issues go, I have never seen 'Silver Swirl'
get so much as a leaf spot from overhead watering,
but as mentioned before, excessively wet media can

cause problems.
Additionally, we
have seen thrips on
this like other
Centaurea.
Spring,
summer, fall
or holidays,
'Silver Swirl' can add
a modern design touch to
your customers' landscape
or container designs. Don't
pass this one up for your next
perennial program! It's a true
stand-out for garden center
and nursery sales.
