Below is our 16 year old clump of the ladyslipper, Cypripedium ‘Rascal’, this week. This amazing Carson Whitlow hybrid is a cross of two North American species, Cypripedium parviflorum var. parviflorum x Cypripedium kentuckiense. As you can see, it thrives despite our summer heat and humidity.
We’re just back from a quick outing to the Flower Hill Nature Preserve in Johnston County, NC…just a few miles from JLBG. This unique coastal plain site contains remnants of species more common in the NC mountains, nearly 5 hours west. The top of the bluff is a small stand of enormous Rhododendron catawbiense, while along the bottom of the hill is a bank of the deciduous Rhododendron canescens.
In the mid-slope area, we found Cypripedium acaule (pink ladyslipper orchid), just waiting to be photographed. Sadly, it’s one of the most difficult species to transplant, so just enjoy these in situ when you find them.
There were beautiful masses of the evergreen groundcover galax, growing on the eastern slope.
It was particularly great to see the Asarum vriginicum in full flower. True Asarum virginicum is rarely seen in cultivation, and the diversity of flower color was outstanding.
We are just starting with the first wave of Cypripedium (ladyslipper orchids) in the garden this week. One of the earliest selections to put on a show is Cypripedium ‘Rascal’, an outstanding cross of Cypripedium kentuckiense and Cypripedium parviflorum var. parviflorum…all US natives.
It was a real thrill last week to visit a population of Cypripedium kentuckiense (Kentucky Ladyslipper Orchid) in Texas with native plant guru, Adam Black. Adam has made numerous trips to this and other nearby sites, carefully pollinating the orchids to ensure seed set and enhance reproduction. While we’ve offered this species as seed-grown plants (8 years from seed to flower) for years, this was my first chance to actually study them in the wild. Cypripedium kentuckiense is one of the easiest ladyslipper orchids to cultivate, thriving in a wide variety of woodland conditions. Here, they were growing just above a seasonally flooded stream in very sandy soils.
I remember when I discovered we could actually grow ladyslipper orchids in the garden, despite so many stories of them being impossible to cultivate. The reality is that one ladyslipper, Cypripedium acaule is tough to move. Otherwise, they’re easy. I just took this photo of our clump of Cypripedium ‘Hank Small’…32 flowers this year! I hope you will give these a try in your light shade garden. A slightly moist soil is best, although this one is grown much too dry under a giant pine tree.
