There are also several registered hybrids available: Yokohama (N. Suzuki 1956 - Bletilla striata
), 'Coritani' (R. Evenden 1994 - Bletilla formosana
), and 'Brigantes' (R.G. & A. Evenden 1994 - Bletilla striata
). I personally grow B. striata
that produce blossoms which are pink with a darker pink lip and B. striata
, a form that produces white blossoms.
Both of these species are hardy down to about 20 degrees o
F (-7 o
C) in the winter (when covered with mulch). In colder areas, you may need to dig up the bulbs much like you would Gladiolus
bulbs or plant them in flower pots
which you can bring into the house for the winter.
I have been successfully growing these little delights around the outside of my greenhouse
for over 20 years. They are watered and fertilized
by the water that drains from my greenhouse which they really enjoy.
I have planted them on both the west and south sides of the greenhouse
to take advantage of the sun, they multiply readily into nice clumps. The flowers are excellent as cut flowers and have a nice soft fragrance.
Every spring these little orchids send up tall leaves with prominent pleats running down them. Then, in early summer, they send up an inflorescent that can reach over 30 inches tall with up to a dozen 1 1/2 inch blossoms.
