Coerulea (blue) Cattleyas

In Cattleyas the ‘coerulea’ color or ‘blue’ as it is referred to, is very intriguing and rare in nature. In the early years of blue breeding there were not many known species, so breeding was limited to a few possibilities. Today, we have many species and hybrids to breed with, and the quality of blue flowers has been improving rapidly. Don’t miss the spotted blue crosses…These are a great addition for the discriminating collector.

Lc. NEW HYBRID (Lc. Love Knot f. coerulea 'SVO' HCC/AOS x C. mossiae f. coerulea 'Blue Moon Too')

Large well-formed coerulea flowers on small plants are the expectation here.  Love Knot is a small plant, only 5” tall, and blooms twice a year with 2 to 3 very flat flowers that are nearly 4” across.  It is an excellent grower and very showy.  C. mossiae f. coerulea 'Blue Moon Too' has large 6.5” flowers of good shape and color.  This plant produces 4-5 blooms on strong stems in early May.  I have high expectations for this cross.  Love Knot is known to flatten flower form, and mossiae provides flower size and is dominant for bloom period.  With this cross, we look forward to 3-4 large flowers on compact, robust plants in May.  A great and very promising cross!  These protocorms were treated with oryzalin (t), a chemical that can double the number of chromosomes.  The hope is that some of these will be tetraploids, and the ones that are will be very valuable.

Lc. NEW HYBRID (C. Blue Velvet 'Surprise' SM/JOGA x Lc. Cornelia 'Floralia')

This modern blue mini-Catt cross benefits from the influence of C. walkeriana and L. pumila.  It also capitalizes on the large flower size of the standard labiate Cattleya species, C.  warneri and C. labiata, in the background of this cross. Plants will stay small, with a maximum height of 8” tall, and flowers will be large, possibly up to 5” across.  Petals and sepals will be in shades of coerulea with full darker blue lips.

Lc. NEW HYBRID (Lc. Love Knot 'SVO' HCC/AOS x Lc. Blue Rose 'Dark Blue')

The ancestors in this cross read like a who's who of modern blue Cattleya breeding.  Love Knot (C. walkeriana x L. sincorana) imparts very flat flowers and color, and has given rise to many outstanding progeny.  Blue Rose (Lc. Floralia's Azul x Lc. Tahoe Rose) is a recent hybrid that produces top-quality blues with very large flowers and beautifully-formed lips on small plants.  This modern blue breeding is really exceptional!  Plants will stay under 10” tall, flowers will be 4-5” across, and the color should be outstanding.

Coerulea flowers with blue spots is pretty cool, but why stop there?  How about adding blue flares on the petals?  Interglossa (intermedia v. aquinii x amethystoglossa) has coerulea flowers with blue flares on the petals and a few blue spots.  Breeding it to the spotted leopoldii f. coerulea will accentuate the spots.  Even though one parent is flared, not all the offspring will produce flared blue flowers, but approximately half will.  Look for spotted coerulea flowers with dark blue lips.

Lc. NEW HYBRID (Lc. Lake Tahoe 'Blue Lake' HCC/AOS x Lc. Ellery Tomaszkiewicz 'SVO Blue Star' AM/AOS)

At SVO we are always looking for the ideal cross that grows well and blooms well with excellent shape and color.  Our blue breeding is coming along very nicely, and progress is being made in all of these areas.  Lc. Lake Tahoe (Lc. Floralia's Azul x L. sincorana) came from Alan Koch at Gold Country Orchids.  It's a mini plant with large, flat, blue flowers that blooms reliably twice a year. Ellery Tomaszkiewicz (Lc. Love Knot x C. warneri) is an excellent cross, with large flower size and good flower count from C. warneri and small plant size with flat flowers from Lc. Love Knot.  This grex will have coerulea color, and the 3-4 flowers will be flat, well-shaped, and presented nicely on good stems.  Flowers will be large in relation to plant size, and I expect twice-a-year blooming.

Lc. NEW HYBRID (Lc. Floralia's Azul 'Sandra' AM/AOS x Lc. Ellery Tomaszkiewicz 'SVO Blue Star' AM/AOS)

Floralia's Azul (Lc. Mem. Jack Hayden x Cattleya walkeriana) has proven itself to be an important breeder of blues.  Its fine shape and color, and free-flowering traits are its strong points.  Ellery Tomaszkiewicz (Lc. Love Knot x C. warneri) is an excellent cross, with large flower size and good flower count from C. warneri and small plant size with flat flowers from Lc. Love Knot.  These are going to have big flowers up to 4.5” across on plants only 7-8” tall.  Flower color will be coerulea, with broad lips in darker blue.  A super nice blue cross!

Compact coerulea breeding is developing quite nicely, and this cross brings together several important traits like large flower size and a compact plant only 7-8” tall.  Flower colors will be coerulea with dark blue lips and a yellow throat, which really sets off the lip color.  This grex combines Cornelis' Love (Lc. Cornelia x Lc.  Love Knot) and Indigo Sky (Lc. Gaskell-Pumila x Indigo Dawn).  This should be a fantastic cross.  Expect 6” flowers on an 8” tall plant – now that's what I'm talking about!

Lc. NEW HYBRID (Lc. Cariad's Mini-Quinee 'Angel Kiss #5' x Lc. Sarah Sears 'Big Blue Sky')
Cariad's Mini-Quinee (Lc. Mini Purple x C. intermedia) was one of the first notable blue flared mini-Catts, and it was cloned and widely distributed.  The cultivar 'Angel Kiss #5' is a clonal mutation with higher quality flowers.  Lc. Sarah Sears (Lc. Cornelia x Lc. Indigo Dawn) has large fragrant coerulea flowers, and the well-formed lip is dark blue with a yellow throat.  Many of these will be flared with dark blue splashes, and the good ones will be spectacular.  All will have large flowers on small plants.  Getting several will improve the odds of finding a flared one.

Lc. Mini Purple f. coerulea (Lc. Mini Purple f. coerulea 'H&R' 4n x self)

This Mini Purple (C. walkeriana x L. pumila) is a tetraploid mutation from a large group of clones flowered in Japan.  It was a real standout, with heavier substance and larger flowers with wider segments.  Selfing a 4n will produce almost 100% 4n offspring, and the overall quality will be exceptional.  This is a rare opportunity.

C. NEW HYBRID (C. leopoldii f. coerulea 'Kathleen' JC/AOS x C. Pittiae f. coerulea 'SVO Best Blue')

Blue spotted flowers – wow, who would have thought?  This cross brings together three important species: C. leopoldii, C. loddigesii and C. schilleriana.  The coerulea color forms of these species are very rare in nature, and acquiring select plants for breeding has taken many years.  This Pittiae has flat flowers with coerulea petals and sepals spotted in darker blue, and a dark coerulea lip with a yellow throat.  The coerulea form of Pittiae already has received four AOS awards, and the next generation should be even better!  Crossing Pittiae with a coerulea leopoldii will reinforce the spotting, increase flower count and strengthen the stem.  This is a super nice and very unusual spotted coerulea cross, and is not to be missed!

This cross adds leopoldii f. coerulea spots and flower count back to the coerulea Gaudii (Cattleya loddigesii x Cattleya leopoldii) with its large flat flowers.  Here we are counting on the coerulea flowers to be densely spotted.  In many ways, this cross will look like a super coerulea C. leopoldii.  Don't miss out!  The same as SVO 7548, but the protocorms were treated with oryzalin (t), a chemical that can double the number of chromosomes.  The hope is that some of these will be highly desirable tetraploids.

C. NEW HYBRID (C.Leoloddiglossa f. coerulea 'SVO Speckled Blue' FCC/AOS x C. Little Leopard f. coerulea 'Nite Shade')

Leoloddiglossa has been a remarkable hybrid, the first highly successful coerulea (blue) flower with darker coerulea spots!!! The lineage of Leoloddiglossa contains three Cattleya species: leopoldii, loddigesii, and amethystoglossa, thus the name: Leoloddiglossa (leo-loddi-glossa).  'SVO Speckled Blue' has excellent shape and color, and carries 20 or more well-presented flowers.  Receiving an FCC/AOS is one of the highest accolades a plant can get.  Little Leopard (C. aclandiae x C. amethystoglossa) is a unique flower, and 'Nite Shade' is the only coerulea color form of this cross I know of.  Flowers are spotted, and the lip is coerulea, as is the column.   This is our first hybrid with Little Leopard, and we anticipate that it will significantly reduce plant size, maintain the coerulea color and spotting, and transmit coerulea-colored columns to some of its offspring.

C. Something Else f. coerulea (C. bicolor f. coerulea 'SVO' x C. schilleriana f. coerulea 'Good Color')

This must be a first in coerulea breeding.  The coerulea color form of bicolor is very rare and has only became available recently.  The coerulea from of schilleriana became available in the late 1980's when the cultivar 'Orchidglade' was cloned and widely distributed.  It is interesting to note that many of these unusual color forms are very rare in nature, and thanks to selective breeding there are many more available in cultivation.  This cross is all about the lips!  Both bicolor and schilleriana are known for their large, broad lips and these coerulea lips really will be “something else.”

Pot. NEW HYBRID (Slc. Jungle Hotspot 'SVO Splash Spots' x Blc. Sunspots 'Sandy' AM/AOS)

One of the breeding ideas I have been working to develop lately is yellow flowers with red spots AND red flares.  Sound interesting?   The idea took hold with Jungle Hotspot (Slc. Jungle Gem x C. Penny Kuroda), which has light-yellow sepals spotted in red, and white petals flared in purple, with an unusual purple lip.  Sunspots (C. Mark Jones x Blc. SunCoast Sunspots) has yellow flowers, bold spots and a red lip. Here we are hoping that the yellow color from Sunspots will improve the color of the progeny, reinforce the spots and still allow for some flares to come through.  This cross is a bit speculative, but sometimes you have to take a chance. Check out the PICTURE   This makes us happy!

The lineage of Leoloddiglossa contains three Cattleya species: leopoldii, loddigesii, and amethystoglossa, thus the name: Leoloddiglossa (leo-loddi-glossa).  'SVO Speckled Blue' has excellent shape and coerulea color, and carries 20 or more well-presented flowers.  This schilleriana has flowers with more blue spots than usual and a large, broad, dark coerulea lip on a plant just 7” tall.  The objective here is to maintain the coerulea color and dark blue spots, increase lip size, reduce plant stature to 10-12” tall and hopefully not reduce flower count too much.  I might name this cross C. Leoloddiglossiana…Outstanding potential here for compact plants with heads of large coerulea flowers with darker spots and a broad flat blue lips.  Not to be missed
