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 S. tigrina var. nigroviolacea forms.  It has flowered from a 3.0 inch (8 cm) pot in two years with five inflorescences, and in that time the plant has doubled in size.  It always seems to be in growth and takes very few breaks throughout the year.  I will continue to monitor this variety and see how it performs against the eleven other forms of this species that I have growing in my yard.

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.

Stanhopea hernandezii with three inflorescences.  This will be the first time I get to see this plant in bloom though I have owned it for three years.  The first year it bloomed I was on vacation and missed the flowers opening.  Last year the buds blasted. This year may be the year the flowers open when I am present.
