CULTURE REPORT
late-summer color in the landscape.
These three varieties make fantastic
patio container subjects and will
continue to bloom until a hard freeze
outdoors. Under shelter, the Velvet
plectranthus has been shown to
survive sub-freezing temperatures
for a short period of time.
'Velvet Lady'
'Velvet Diva'
CROP PLANNING
* Plant one rooted cutting in
a 4- to 5-inch pot.
* Plant two rooted cuttings
per 6-inch pot.
* Plant three to five rooted
cuttings per 10-inch pot.
FINISH TIMES
These varieties will finish a
4- to 5-inch pot in six to nine
weeks; a 6-inch pot in seven to
10 weeks; and a 10-inch pot in
eight to 11 weeks.
All the plectranthus Velvet
collection plants respond quite
evenly to forcing. Light deprivation
for 13 hours a day (11-hour short
day) will give a response in four
to five weeks. Once floral initiation
has started, resume a less than
12-hour day at 4,500 to 7,000
foot-candles to finish.
INSECTS AND DISEASES
Velvet plectranthus are
remarkably carefree, rarely
bothered by foliage and root
diseases. Pythium symptoms are
usually caused by overwatering
and too cool night temperatures.
Thrips and aphids are rarely
problems for plectranthus. Watch
for white fly and control them as
soon as possible to avoid marring
the foliage prior to sale.
RECOMMENDED USES
Plectranthus 'Velvet Idol' and
'Velvet Starlet' are best used for
a 4- to 5-inch program. They will
lend themselves to a number
of programs, from chain store
premium annuals to grocery store
grab-and-go color. These two
varieties have high-color impact
and are novel in both size and
flower power.
'Velvet Elvis', 'Velvet Lady' and
'Velvet Diva' are each well suited to
5- to 10-inch programs for bold,
