Cypripedium Orchids

Cypripediums (Lady-Slippers)

Lady-Slippers (Cypripedium) are a stunning group of hardy orchids, and one of the easiest of the hardy orchids to grow. In the shade garden they put on a yearly show that is unmatched - a celebration of spring that often stops one in one's tracks. Their blooms are ancient and seem to have the power to stir something deep inside us.

For many years, and even today, there persists the notion that lady-slipper orchids are too difficult to grow and should be left to the experts. With the availability of nursery propagated plants, (and when one starts with plants from a reliable source) this is no longer the case. With proper care in planting and site location (as with any perennial you value), Lady-Slippers will not only grow, but over time will form large clumps which tend to be very long-lived.

If you're interested in trying to grow lady-slippers but are unsure, we recommend starting with one of the easier forms and then see how it goes for you. Of our list below all are relatively easy except for Cyp. reginae. Much of our business over the years has been from repeat customers, many of whom have started slow and have gone on to build large collections.

Please Note: These are NOT tropical orchids.

Cypripedium 'Rita Alba'

Cypripedium 'Rita Alba'

(C. andrewsii cultivar)

There is a bit of a story to this one. The parviflorum var. makasin, aka 'Rita' part of the cross, originally came from the Putney Garden Center in Vermont in the mid 1950s. It spent 35+ years in gardens in Amherst, MA before I was given a division from a gardener named Rita in the early 1990s, and so we have always referred to this very distinct form by her name. 'Rita' is a charming dwarf form of parviflorum var. makasin. I set out to grow more of them and it seems that some insect beat me to the pollination and crossed it with C. candidum, producing a surprise batch of the hybrid andrewsii. Where other andrewsii I've grown tend to come up too fast and then flop over, Rita Alba is compact. It comes up slow and sturdy. Its blooms have creamy white pouches with reddish-brown veining and dark brown sepals and petals. It usually blooms early-mid season.

Zones 3-6. 8-10 in. Light shade, cool moist rich well-drained soil.

We are offering Blooming-sized plants with at least one large blooming stem and well developed root system.

Cypripedium kentuckiense

Cypripedium kentuckiense

KENTUCKY LADY-SLIPPER or SOUTHERN LADY-SLIPPER

The largest flowered of all the Cyps, with pale yellow blooms on tall stems. The last to bloom for us, starting here in late May into June, lasting for one-and-a-half to three weeks, depending on weather conditions. One of the easiest to grow, over time. C. kentuckiense will form large clumps and persist for years. A native of Kentucky and ranging south to Louisiana, it can be grown successfully as far north as Zone 3. It is the most tolerant of high summer soil temperatures. In the wild it is found growing in rich neutral moist-but-well-drained soil.

Zones 4-8. 16-30 in. Light shade, moist rich well-drained soil, with approximately neutral pH.

We are offering Blooming-sized plants with at least one large blooming stem and well-developed root system.

SMALL YELLOW LADY-SLIPPER

Small deep yellow flowers with brown veining and long brown to black corkscrew sepals. Often bifloral (two flowers per stem). This small northern form, often called the Yellow Moccasin Flower, is easy to grow and will form large clumps over time. They usually start blooming here a little later than Cyp. pubescens with some overlapping.

Zones 3-7. 14-20 in. Light to part shade, moist rich well-drained soil, with approximately neutral pH.

Cypripedium pubescens

LARGE YELLOW LADY-SLIPPER

Large deep-yellow flowers with long yellow-to-brown corkscrew lateral petals. Probably the easiest native orchid to grow, it will form large clumps of over 20 blooms in time when happy. It is the first species cyp to bloom in late April or early May here for us, blooming over a 2-3 week period. Native from Minnesota to the Canadian Maritimes in the north, and south from Missouri to Georgia. In the south it is usually found in cool rich woods and coves where there is shade most of the day, though in the north it is often found in more open conditions, sometimes in full sun. In the wild it grows in both sub-acid and circumneutral soil, and with a more moderate moisture supply than the other Lady-slippers.

Zones 3-7. 14-24 in. Light to part shade, moist rich well-drained soil, with approximately neutral pH.

We are offering Blooming-sized plants with at least one large blooming stem and well- developed root system.

Cypripediums: Hybrids (Hybrid Lady-slippers)

While the purists often gravitate to growing the species, there's a lot to be said for the value of hybrids in the garden. All the same qualities of the species still apply here but, for many, we also have the addition of some new colors along with hybrid vigor. 

We are also really excited about a number of new multi-cross hybrids coming along.  These plants have exceptional vigor which makes them a bit easier to grow in the garden.  

Cypripedium 'Aki '

Cypripedium 'Aki'

(C. macranthos x C. pubescens)

This hybrid form tends to have very large flowers with light pink pouches and burgundy and cream streaked petals and sepals. Flower size and color does vary somewhat. We have seen some variation in our new batches that include light and dark pink, even some creamy yellow streaked with pink. It is the first to bloom here at the nursery with C. 'Gisela' flowering just behind it.

Zones 3-6. 16-24 in. Light shade, cool moist rich well-drained soil.

We are offering Blooming-sized plants with at least one large blooming stem and well-developed root system.

Another new tripple cross hybrid for us this year. We've seen it flower a couple years now and it's a very nice plant with good vigor. There is some variation among the flowers, but for the most part it is a medium-sized light to dark pink slightly elongated slipper with darker pink tendrils.

Cypripedium hyb kentuckiense x candidum

Cypripedium kentuckiense x C. candidum

This is one of our favorite lady-slippers here at the nursery. The pouch is a glossy white on the outside with burgundy streaks along the inside ridges. The hood and tendrils are a dark burgundy, almost brown. The bloom size is about halfway between the two parents, making it close to the same size as a C. pubescens.

Cypripedium Laila

Cypripedium 'Laila'

Cypripedium macranthos x C. x andrewsii (where C. x andrewsii = C. candidum x C. parviflorum)

Laila has turned out to be a very nice surprise--- the reason why we like trying 'tri' crosses. Its looks are dominated by the macranthos with a medium-sized deep burgundy, streaked pouch. It has deep burgundy tendrils and its vigorous growth habit comes from the mixing of all three forms. It blooms mid-season. This is a rare find and our stock is quite limited.

Zones 3-6. 12-18 in. Light shade, cool moist rich well-drained soil.

New!
(Cypripedium kentuckiense x C. candidum) x C. 'Rita Alba'

The Rita Alba in this cross is a variation on Cypripedium x andrewsii where the parviflorum of that cross is from a woman's garden. A woman named Rita. She had a makasin form of Cypripedium parviflorum var. parviflorum from Vermont. When we crossed it with C. candidum we named the resulting plant after her.

These are nice small to medium lady-slippers that mostly have white pouches and dark tendrils, however we have seen some variation with a light yellow pouch here and there. This is another quadruple cross so expect good vigor with these plants as well.

Zones 4-7. 10-16 in. Light shade, cool, moist, rich well-drained soil.

C. Pubescens x ((C. pubescens x C. kentuckiense) x C. parviflorum var. makasin)

We croseed Pubescens with PKParv which is a tri-cross between the three eastern North American yellow lady-slippers. The first cross, PK, has been an outstanding plant from carefully selected parentage. To this, we have added a strong-growing C. parviflorum var. makasin with a deep yellow pouch and dark brown, spiraled tendrils.

The resulting quadruple crosses are somewhat variable plants with medium-sized yellow blooms and a vigorous growth habit. It blooms mid-season.

Zones 3-6. 16-20 in. Light shade, cool moist rich well-drained soil.

The Rascal in this cross combines the large-flowered, easy going, and heat tolerant Kentucky lady-slipper with the rugged, very cold tolerant northern form of the small yellow lady-slipper. We then back-crossed Rascal with C. kentuckiense. The result looks very similar to a C. kentuckiense with blooms on the mid- to large-size, yellow with brown tendrils. Bloom time is mid-late season.

Zones 3-8. 14-18 in. Cool, moist, well-drained soil with a mulch cover. Light shade (early morning or late afternoon sun is OK).
