 This is a selection of
H. longipes latifolia
from
an unknown originator which was registered in 2009 by
Kevin Walek (Hosta Registrar) of Virginia
and
re-registered
with new data in
2018. It
is a small size hosta which grows to 8 inches in height with a spread of
around 20 inches with a semi-upright growth habit. The foliage has smooth texture on its shiny
medium green leaves with a greenish yellow marginal variegation. Lavender flowers
with translucent edges
are borne in September.
  Nomenclature changes recommended in the
1991 book
The Genus Hosta by
W. George Schmid and accepted by The
American Hosta Society would update names as follows:
H. tortifrons is now H. 'Tortifrons'
and H. tardiflora is H. 'Tardiflora'.
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term iwa as rock, Iwa Gibōshi or
H. longipes and the term maruba as round leaf or round-leafed.
 An article
about Fall Bloomers by
Herb Benedict
and
Jim Wilkins in
The Hosta Journal (1991 Vol. 22 No. 1) states that, "Here are some of
the fall blooming plants we grow...(listed in the order of bloom times in
Michigan).
| 1) H.
kikutii
|
A medium size plant densely flowering
with white blooms. The flowers are equally arranged around the
central axis of the raceme so that the bloom scapes resembles a
bottle brush or pony tail...We are growing two named varieties, 'Hirao-59'
and 'Finlandia'. |
| 2) H. 'Fall
Bouquet' |
Small, green plant, leaves slightly
undulated, lavender scape and blooms, floriferous. |
| 3) H.
longipes |
Small green plant, densely flowering
with a tall stiff bloom scape. The flowers are lavender and the
leaves are green. |
| 4) H.
gracillima |
Funnel-shaped, light lavender flowers.
A miniature green plant, with shiny surface. |
| 5) H. 'Iwa
Soules' |
Iwa means rock, and this plant was
imported by
Marjorie Soules, from
Japan. It is a small green plant with lavender flowers. |
| 6) H. tortifrons |
In the same section (Picnolepis) as
H. longipes and
H. rupifraga.
Distinctive small plant, with twisted green leaves and lavender
flowers. |
| 7) H. 'Fused
Veins' |
Small, green leaves often with ¼ inch
margin which is a lighter green. The lance shaped leaves are
undulated and the veins come together regularly. The flowers are
mauve and the scape is sometimes branched. |
| 8) H.
rupifraga |
Small, medium green, with thick,
leathery, ovate leaves. Densely flowering with purple flowers.
'Urajiro', 'Grand
Slam', 'Maruba Iwa' |
| 9) H. tardiflora |
This small hosta is the last to bloom
for us. Its leaves are shiny, dark green and lance shaped. The
flowers are light lavender and borne in abundance on 12 inch scapes. |
Herb Benedict and
Jim Wilkins include their
observations about using fall blooming hostas in hybridizing programs:
| |
|
| 1) H. tardiflora × self |
Tends to flower 2 weeks earlier. 90% of
the progeny have the flowers secund (flowers all on one side of the
bloom stalk) and in 10% they are evenly arranged around the central
axis of the raceme (nonsecund). |
| 2) H. rupifraga × H. tardiflora |
Beautiful very tough plant with a
taller bloom stalk. Blooms 2 weeks earlier. |
| 3) H. 'Maruba Iwa' × H. tardiflora |
Taller bloom stalk. Blooms 2 weeks
earlier. 30% of progeny have nonsecunded flowers. |
| 4) H. gracillima × H. tardiflora |
Very nice small plant, with leaves
intermediate between the two. Beautiful flowers. |
| 5) H. rupifraga ×
H. kikutii |
The best of this cross is called 'Roys
Pink'. It is a perfect intermediate. The leaf is long, heart shaped
and very thick. The flowers are pony tail in type, a light pinkish
color and spent flowers drop off cleanly. |
