Coerulea (blue) Cattleyas

In Cattleyas the ‘coerulea’ color or ‘blue’ as it is referred to are very intriguing and rare in nature. In the early years of breeding for blues there were not many known species in this coerulea color. 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 vastly improved. Plant habit and speed to bloom have also been improved. There are several new trends in breeding with blue flowers the development of blue flares and bifoliate blues. These are truly new breeding lines and well worth acquiring a few.


SVO 1432

Lc. Cariad’s Mini-Quini (Lc. Mini Purple var. coerulea ‘Blue Hawaii’ AM/AOS x C. intermedia var. aquinii, coerulea ‘Haneda’ AM/AOS)

Flared, coerulea mini-cats are just becoming available. Mini Purple (C. walkeriana x L. pumila) is an easy growing plant with light blue flowers and a darker blue lip. The C. intermedia ‘Haneda’ AM/AOS is a well formed light blue flower with aquinii flares. All will be blue with about 50% with blue flares; these will also be compact growers

SVO 1598

Lc. Cornelia var. coerulea 'Floralia' x C. intermedia var. aquinii 'Blue Splash'

Coerulea blue Cattleyas have been popular for some time now, but here we are breeding for splashed petal blue flowers! Cornelia is a fine parent and is a primary hybrid of (L. pumila x C. labiata). By combining it with the blue splash petal C. intermedia var. aquinii, we are looking for light blue flowers, 50% with darker blue flares and lip. A new color development in compact Cattleyas

SVO 1613

C. jenmanii var. coerulea x sib

The seed also came from Greg Allikas. Coerulea varieties of Cattleya species are very rare and much sought after. Here we have a selfing of one of Greg’s finest blue C. jenmanii. These are very limited.

SVO 1694

Lc. Love Knot var. coerulea 'SVO' HCC/AOS x C. luddemanniana var. coerulea 'Kathleen'

Love Knot is a fine parent producing flat flower form and is a primary hybrid of (L. sincorana x C. walkeriana). By combining it with the large flowered coerulea ‘Kathleen’, we are looking for large blue flowers while maintaining small 6”-8” tall plants.

SVO 1740

C. mossiae var. coerulea ‘SVO’ x C. mossiae var. coerulea 'Good Lip'

Two superb coerulea forms crossed together. C. mossiae blooms for Mother’s Day. Don’t miss out on these.

SVO 1742

C. Pittiae (C. loddigesii var. coerulea 'Blue Sky' AM/AOS x C. schilleriana var. coerulea ‘Orchidglade' AM/AOS)

Here we are breeding for spotted blues! This primary hybrid is similar to C. Brabantiae (C. loddigesii x C. aclandiae), expect with improved flower count due to the influence of C. schilleriana. The plants are expressing clear green foliage with a slight grey cast on the developing sheaths. I believe this is an indicator of light blue flower color and darker blue lips, however a few pink ones may appear. The blue flowered forms will be extremely collectable. Don’t miss out on these.

SVO 1753

C. Lawre-Mossiae (C. mossiae var. coerulea 'SVO' x C. lawrenceana var. coerulea 'Pedrito')

I first saw this cross in Venezuela made with the normal colored forms and I was really impressed. While in Venezuela I was able to acquire the pollen of the very rare coerulea color form of C. lawrenceana, the plant had 8 beautiful flowers. The mossiae is one of my best with dark coerulea flower color and good plant growth characteristics. These are growing well and should be very nice coerulea’s.

SVO 1798

C. Landate (C. aclandiae var. coerulea 'Blue Sky' HCC/AOS x C. leopoldii var. coerulea)

The first Landate made with coerulea parents! The aclandiae v. coerulea is considered very rare with its dark blue lip. The leopoldii is olive green with a coerulea blue lip. We are hoping for a few to have olive green flowers with blue lips. The blue flowered forms will be very collectable.

SVO 1823

C. loddiglossa var. coerulea x C. leopoldii var. coerulea

The Loddiglossa (C. amethystoglossa x C. loddigesii) has 9 to 11 light blue flowers with darker lips, produced on a 12” inflorescence. The leopoldii blooms with 10 or more flowers, the petals and sepals are green, the lip and part of the column are blue. Our first batch of these have all flowered out in shades of blue with darker lips! These are very collectable bifoliate coerulea Cattleyas. Highly recommended and not to be missed. Here is a picture of the first to bloom 1443

SVO 1923

Lc. Cornelia var. coerulea 'Floralia' x Lc. Love Knot var. coerulea 'SVO' HCC/AOS

This is similar to a Japanese hybrid Lc. Mini Blue Star (Lc. Cornelia x Lc Mini Purple). There are just 4 species involved in this cross: Cornelia (L. pumila x C. labiata) and Love Knot (L. sincorana x C. walkeriana). Look for very compact growing plants with coerulea blue flowers and darker blue lip. Here is a picture of the first to bloom 1464

SVO 1937

Lc. Alarcon 'Gran Blue Jeanne Marie' AM/AOS x C. intermedia var. aquinii, coerulea 'Blue Splash'

Alarcon (Lc. Canhamiana x C. Dupreana) has received many awards for size and coerulea color of the flowers. Splashed blue flowers are a new breeding trend, the introduction of the intermedia var. aquinii, coerulea 'Blue Splash' will give this desired flare to the petals in about 50% of the cross. The best will be very nice.

SVO 1945

C. luddemanniana var. coerulea 'Kathleen' x C. luddemanniana var. coerulea 'Francisco'

Good coerulea luddemanniana are very expensive, here we have combined two excellent cultivars. These are growing beautifully with good vigor. The ‘Francisco’ cultivar is one of the best from the new line breeding out of Venezuela. I have purchased many imported seedling of this coerulea form for a lot more $’s each…..
