Striped Spice
[M. x soulangeana], cv. (Magnolia 29(2)
[Issue 56]: 25, 1994). ‘This cultivar originated as a seedling of M.
liliiflora and is probably a backcross of M. x soulangeana onto M. liliiflora.
Flowers resemble those of typical M. x soulangeana with a fairly distinct
red-purple (RHS 70C) strip running the length of the tepals. The flowers have
9 tepals, about 4 in. long by 2 in. wide; there are no sepaloid petals. Unlike
most soulangeana cultivars, ‘Striped Spice’ has a strong spicy
fragrance, similar to crushed Lindera leaves, which is very pleasant. It blooms
a few days to a week later than the typical trade clones of soulangeana. This
form is hardy to USDA zone 6, possibly 5. It was registered in June, 1994,
by Richard B. Figlar, Pomona, New York.’

[M. acuminata], cv. (Magnolia 29(2) [Issue
56]: 26, 1994). `Richard B. Figlar, Pomona, New York, selected this cultivar
from a wild population in Lysander, New York, 20 miles northwest of Syracuse
near Beaver or Mud Lake. This form is typical M. acuminata except that the
leaf margins have virtually no undulations. Figlar selected the cultivar primarily
to provide genuinely hardy genetic material for magnolia breeders. The flowers
of `Syracuse’ are smaller than typical. Figlar notes that M. acuminata
is becoming rare in upstate New York due to the clearing of land for agriculture.
He registered this cultivar in June, 1994. An herbarium specimen (Voucher
#1459) is located at Clemson University.’
