  • Stanhopea impressa

    Stanhopea Culture Sep 5, 2015 | 15:01 pm

    Stanhopea impressa This species is native to the western foothills of the Andes Mountains and is found in moist montane forests in Colombia and Ecuador.  The orchid grows at elevations between 1,640 to 6,000 feet (500 to 2,000 m).  The 4 inch (10.2 cm) wide flowers are cream colored to white and have a few sparse reddish spots along the petals and more on the sepals, hypochile and column. The center portion of the flower is infused with an intense yellow-gold color. The fragrance of the flowers is similar to basil and is slightly herb-like, but with an undertone of moth balls.Stanhopea impressa inflorescenceThis is[…]

  • Stanhopea gibbosa

    Stanhopea Culture Aug 28, 2015 | 18:45 pm

    Stanhopea gibbosa This orchid is native to wet and humid forests of Costa Rica, Nicaragua, and Panama and grows best in intermediate temperature conditions .  It grows from 1,640 to 4,920 feet in elevation (500 to 1,500 m).  The 4.5 to 5 inch (11.4 to 12.7 cm) flowers are yellow to cream colored and have several reddish spots on the sepals, petals, and hypochile.  The flowers have a nice scent of Eucalyptus, menthol, and pine mixed together.  This species is often confused with Stanhopea costaricensis, but this species appears to have a more prominent and consistent form with two bulges at the back of the[…]

  • Stanhopea tigrina var. nigroviolacea

    Stanhopea Culture Aug 15, 2015 | 22:53 pm

    Stanhopea tigrina var. nigroviolacea This form of Stanhopea tigrina var. nigroviolacea is a recently flowered plant that I received in a trade.  The original plant was grown in Germany and this doesn't seem to be a form that is common here in California.  It has flowers that are medium sized at approximately 5 inches across. The yellow color on the petals and sepals is rather intense and the reddish brown stripes are uneven on the upper dorsal sepal.  It will be interesting to see how consistent the flowers are from one year to the next.  Perhaps this plant has more variation in the flowers than I have[…]

  • Stanhopea oculata 'Two Eyes'

    Stanhopea Culture Aug 2, 2014 | 04:20 am

    Stanhopea oculata 'Two Eyes' This form of Stanhopea oculata is very similar to the standard form we see in many nurseries in southern California, that has buff to yellow colored flowers and many reddish brown spots on the petals and sepals.  However, this form has brighter yellow sepals and more spots on the sepals than the other form I have. This form also only has two eyes spots on the hypochile unlike the other form that has four.  This isn't that noticeable of a difference, just something interested I noted.  The fragrance of this form is still the same intense mint and chocolate that[…]

  • Stanhopea tigrina var. nigroviolacea 'Glory of Mexico'

    Stanhopea Culture Jul 14, 2014 | 03:43 am

    Stanhopea tigrina var. nigroviolacea 'Glory of Mexico' This form of Stanhopea tigrina has a soft yellow or buff background and less of the reddish brown markings on the petals and sepals than some other forms like 'Predator'. The yellow markings on the upper hypochile are also more intense in this form.  The flowers are as large as the other forms with a width of 6.1 inches (15.5 cm).  The fragrance is very similar to the others with a chocolate and vanilla scent, but this has a slight mothball fragrance as the flowers age.For me this has been one of the most rapidly growing and rewarding of the[…]

  • Stanhopea hernandezii

    Stanhopea Culture Jun 27, 2014 | 03:01 am

    Stanhopea hernandezii This species is native to Mexico in a narrow range on the southwest side of the Trans-Mexican Volcanic Belt at lower elevations from 5575 to 7220 feet (1700 to 2200 m) in moist forests with a seasonal dry period.  The range includes the states of Guerrero, Mexico, Michoacan and Morelos.  This Stanhopea grows as a semi-terrestrial and lithophyte in shallow soil over rock or in decaying leaf litter.  Because of the decrease in winter rainfall and growth with little cover, this orchid tends to dry out a bit over the winter and this initiates flowering in late spring and summer. […]

  • Spring 2014 Inflorescences

    Stanhopea Culture Jun 19, 2014 | 03:57 am

    Spring 2014 Inflorescences This past winter was warm and dry which made it difficult to keep the Stanhopea watered and fertilized.  This warmer weather continued through spring when temperatures were averaging a few degrees above normal for several weeks.  The warmer weather has prompted inflorescences to grow and mature a few weeks earlier than normal.  I expect blooms to open  in the next few days.A Small division of Stanhopea tigrina var. nigroviolacea 'Glory of Mexico' that has waited the last two years to bloom and is producing five well spaced inflorescences!Stanhopea hernandezii with three inflorescences.  This will be the first time I get[…]

  • Stanhopea oculata (purple spot form)

    Stanhopea Culture Nov 13, 2013 | 16:22 pm

    Stanhopea oculata (purple spot form) This is a different form of S. oculata that blooms later in the fall than the yellow form that blooms in early summer.  This form has a cream to buff background color on the petals and sepals and also has dark purple spots.  The spots are rather dense on the upper hypochile and there are several dark pink to purple spots near the eye spots on the hypochile as well as on the epichile.  The upper hypochile has a bend that is greater than 90 degrees, but this form does seem to fit into the S. oculata complex.  The upper[…]

  • Southland Orchid Show 2013

    Stanhopea Culture Oct 30, 2013 | 15:46 pm

    Southland Orchid Show 2013 Two Stanhopea were on exhibit at the show, and the owner Joe Kles of the Riverside/San Bernardino Orchid Society did a great job bringing these species to into bloom again just in time for the show this year.  I am very envious that he was able to get the timing of these to bloom just right since my Stanhopea missed blooming for the show by a week.Stanhopea graveolens inflorescenceStanhopea ruckeri flowerIn addition to Joe, the Huntington Library, Art Collections, and Botanical Gardens also exhibited several Stanhopeinae.  It was good to see several species in bloom for the show.Acineta mirayae Acineta superba almost in[…]

  • Acineta chrysantha

    Stanhopea Culture Oct 22, 2013 | 15:04 pm

    Acineta chrysantha Acineta is a genus of orchids that is part of the Stanhopeinae, and is native from Mexico to South America.  They are large plants with big pseudobulbs that have 2-4 leaves per pseudobulb.  The inflorescences can be 11.8 to 27.5 inches (30 to 70 cm) long.  This orchid is native to moist cloud forests of Costa Rica, El Salvador, Guatemala, and Panama. It is found at elevations from 4,265 feet (1,300 m), and is a warm to cool growing orchid.  I grow this species outside with Stanhopea on the north facing side of my house in partial shade.

  • Stanhopea oculata (gold form)

    Stanhopea Culture Oct 5, 2013 | 15:00 pm

    Stanhopea oculata (gold form) Stanhopea oculata (gold form) inflorescenceThis is a different form of Stanhopea oculata that I purchased because it has golden yellow flowers that are more intense than the other forms of the species.  The upper hypochile has a deep golden yellow color and the sepals and petals are a light to golden yellow color. This form also blooms at a later time (late summer/early fall)  than the pale cream to yellow colored form, and it only has two large eyespots on the upper hypochile rather than the four in the pale form. The eyespots and spots on the petals and sepals are[…]

  • Stanhopea Fall Culture Checklist

    Stanhopea Culture Oct 3, 2013 | 13:02 pm

    Stanhopea Fall Culture Checklist  As the weather begins to cool, fall is a great time to enjoy Stanhopea blooms and watch new growths emerge.  This is also a good time to repot or rebasket plants because it is still warm and many Stanhopea will continue growth through fall.  By the end of December, most warm growing Stanhopea will complete their growth cycle, and wait for spring/summer to continue growth in preparation for summer or fall bloom. ·         Continue watering all Stanhopea regularly and keeping them moist.  I usually water these orchids three to four times a week under normal temperature conditions.  If temperatures rise above 90°F[…]

  • Stanhopea tigrina 'SanBar Gold'

    Stanhopea Culture Sep 28, 2013 | 03:53 am

    Stanhopea tigrina 'SanBar Gold' S. tigrina var. nigroviolacea 'SanBar Gold'    This is another spectacular form of the Mexican species Stanhopea tigrina var. nigroviolacea.  These are the first flowers that have been produced by this plant, but it is a rather vigorous form and produces several growths per year.  I am looking forward to additional inflorescences next year. The flowers have some of the most intense colors of yellow-gold I have seen in this species.  The infusion of gold is most prevalent at the sepal and petal tips and even into the horns. S. tigrina var. nigroviolacea 'SanBar Gold' showing gold color on back of sepalsThe deep gold[…]

  • Stanhopea ruckeri var. alba

    Stanhopea Culture Sep 22, 2013 | 15:16 pm

    Stanhopea ruckeri var. alba This is the form of S. ruckeri that lacks red in the flowers, with no eye spots and no red spots on the petals, sepals, hypochile and column.  The flower is a clean off-white color with green to green blue color infused into the sepals and petals.  The hypochile is a deep yellow color at the base and ivory white on the epichile.  The column is white with a well-defined blue-green infusion of color in the center that is often not captured well in photographs.  Altogether this is a good representative of the crisp and clean color combinations of an[…]

    Stanhopea stevensonii This orchid is native to Colombia.  It grows in intermediate to warm mountain forests at approximately 1,312 feet (400-m) in elevation.  This species requires shade and copious amounts of water.  I grow the plant on the north side of my house, and  it appears to need more shade thus it grows better here than with greater sun exposure.  This species has golden yellow flowers with pale red eye spots on the upper hypochile, and few small red spots on the petals and sepals.  There are also small red spots on the epichile and column.  The fragrance of this Stanhopea is[…]

  • Cirrhaea dependens

    Stanhopea Culture Sep 4, 2013 | 09:58 am

    Cirrhaea dependens This is a small to medium sized orchid that is native to Brazil and found in seasonally dry forests from elevation of 2,297 to 3,937 feet (700 to 1200 m).  The orchid grows in warm locations and requires part shade to prevent the leaves from burning.  It does well in conditions that are similar for growing most Gongora.  The inflorescences are pendulous  1.0 to 1.3 feet (30-40 cm) long, and emerge from the top of the growing medium, so it is best to grow this orchid in baskets.Cirrhaea dependens flower "dark form"The flowers are resupinate so even though the inflorescence[…]

  • Stanhopea ruckeri

    Stanhopea Culture Aug 24, 2013 | 06:22 am

    Stanhopea ruckeri This orchid is native to Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua.  It grows in intermediate to warm mountain forests 2,625– 4,593 feet (800-1400 m) in elevation.  This is also one of the easiest species of Stanhopea to grow outdoors here in southern California, and can take early morning sun and dappled shade the rest of the day.  The form pictured here is one of the spotted forms with pale red eye spots on the hypochile and small red spots on the petals and sepals.  There are also small red spots on the epichile and column.  There are some forms[…]

  • Stanhopea Romp 1 - Andy's Orchids

    Stanhopea Culture Aug 10, 2013 | 15:52 pm

    Stanhopea Romp 1 - Andy's Orchids I was pleased that Andy Phillips from Andy's Orchids agreed to assist me with documenting historical live collections of Stanhopea collected in the wild, and we met at the nursery to discuss this and other research. As always, Andy is a wealth of information on orchids - a real walking encyclopedia.  In between visits from clients I had an opportunity to have a tour of the nursery that is a guided affair.  I had a nice time discussing the trials of Stanhopea cultivation with one of Andy's horticulturalists Katrin.My favorite place in the nursery is of course "Stanhopea Alley".  Stanhopea are found in many parts[…]

  • Stanhopea oculata

    Stanhopea Culture Aug 10, 2013 | 15:44 pm

    Stanhopea oculata This species is native to Mexico and Central America (perhaps south to Brazil) from elevations of 3,280-9,842 feet (1000 to 3000 m). It is found in foothill and mountain forests and it grows in intermediate to cool conditions.  This is one of the Stanhopea that can easily grow outdoors in coastal southern California and requires shade and high humidity to perform well. The flowers are moderate sized 4.3-4.5 inches (10.8-11.4 cm) wide, and there are many forms that are buff colored to bright yellow.  There is a considerable amount of variation in color and quantity of spots on the petals[…]

    Tigrina Trio I have three forms of S. tigrina var. nigroviolacea blooming at the same time this summer.  The flowering has been exciting because every day another inflorescence opens and more flowers appear, filling the garden with overwhelming fragrance.  The S. tigrina var. nigroviolacea 'Predator' that I have had for over eleven years has produced an inflorescence with three buds for the first time.  The plant has always produced two buds per inflorescence in the past.Stanhopea tigrina var. nigroviolacea 'Predator' exhibiting an inflorescence with three buds Once the flowers open, you end up loosing the effect of having three buds on the inflorescence Two other forms have also produced several inflorescences that may keep the garden filled[…]
