Cypripedium - Temperate Ladyslipper Orchids

Fall List 2020

Ordering

You may order and pay in two ways, by Check using our order form or by Paypal, using your Credit Card or PayPal account, directly from the website.

Our Fall 2020 List is now open. Plants may be ordered for shipment in October once they become dormant. Please keep in mind that GPH is a hobbyist grower of Cypripedium and some other terrestrial orchids. We make crosses and raise plants to blooming size to assess the qualities of flowers from the new crosses. We sell excess plants once we have assessed the flowers to make room for new seedlings from new crosses. Thus, our stock of any given species or hybrid is limited in number. We will endeavor to note on our list when our stock of a certain plant is sold out, but during a day, we may receive more orders than that number of plants we have. We will let you know immediately when we realize that has happened and we will refund your payment immediately.

The plants we sell as 'blooming size' have bloomed at least one year. This does not necessarily mean that the plant you receive will bloom next Spring, but more often than not it will. Some species and hybrids may abort their bud the first Spring after being transplanted. This is a response to being moved.

It is also important to keep in mind that the plants we sell will have a variable number of growth buds. The price at which we sell is for one growth bud but often there is more than one bud, the 'extras' are bonuses to the buyer. Sometimes we sell plants with specific numbers of buds but we dont do this often as the plants are grown in beds and it is difficult to determine exactly how many buds a given plant has without disturbing it a great deal.

Many of the hybrids and some of the species we sell are 'new.' For a species this means that it has not been in cultivation extensively so we do not have a good feel for how long a plant may survive in your planting bed. We know it has grown in cultivation for at least 5 years since all of our plants are seed-grown but we dont know with certainty what the breadth of conditions in which they survive might be. We let you know this in our descriptions. These plants are for those who have experience with Cypripediums and are prepared to lose them. We sometimes sell Cyp lichiangense or Cyp arietinum. These often last for a few years but all too soon are lost. All of us who have kept Cyp's have killed very many! While some species and hybrids last for very long periods of time - Cyp reginae, Cyp pubescens, Cyp Gisela and so forth are very difficult to kill and we have specimens that are more than 15 years old, many new hybrids do well, but over a few years tend to decline and are eventually lost. This is the case for many hybrid plants including orchids. Since most of the hybrids we sell have only been in existance for 5-10 years, it is natural to expect that some will not be long-lived. We note in the descriptions some that have done very well for us for many years. If you are looking for good garden plants for your perennial beds in shady sites, keep to these.

Finally, we ship our plants bare root in clear plastic bags. Having a clear plastic bag allows you to become comfortable or not with the quality of the plant when it arrives. If you do not like the look of a rhizome when you receive it we are happy to take it back as we want you to be happy with the plants you receive. This also means that if you order from us, it is with the understanding that we cannot be responsible for issues that become apparent after you plant your rhizome. The rhizomes are in good condition when we dig them or we dont send them on to you. On very rare occasions we find there is a quality or suitability issue. For example, some years ago we received Cyp Sebastian, very nice plants from an outside source. We kept some and sold some. The next Spring, we found that ours had degraded in our beds. This was not due to the quality of the plants but rather their inability to tolerate conditions outside of those in their native habitat at above 5000 feet in the Rocky Mountains (the habitat of one of their parents, Cyp montanum). Since we had sold the plants as hardy in our conditions and they were not, in the Spring we contacted customers who purchased them and told them of our findings, and if the plants had not survived for a customer we refunded their purchase price. Outside of instances in which the plants we sold you were from beds that subsequently failed as in this example, we do not replace plants.


Plants

In addition to listed plants, we also sometimes have available limited numbers of unlisted plants - please contact us if you are looking for something we do not have. If we do not have it, we will help you find someone who does.

Due to the difficulty and costs of obtaining phytosanitary and CITES certificates, we can only ship within the United States.

   Species

Cypripedium californicum

Cypripedium californicum
Blooming size plant
Sold Out
for PayPal click:

Cyp californicum would last for 2-3 years when we planted them in Connecticut. I don't think the summer heat killed them as the plants looked good all summer; I believe the cold winters got them. Cyp californicum occurs in a small area along the California-Oregon border. The summers have hot days but the winters are quite mild with the lowest winter night temperatures in the low-mid 20's. I have not had Cyp californicum in many years but Anthura had some for sale at an enormous price (the price I list above is essentially the price I paid) so I bought a few to give a whorl now that I live in the same horticultural zone as their natural habitat. I would be willing to sell two of them to someone who wants to try them. When I last kept them, I was able to germinate the seed easily so if I am fortunate enough to get blooms I will pollinate and raise some seedlings.


Cypripedium cordigerum

Cypripedium cordigerum
Blooming size plant
Sold Out
for PayPal click:

Cyp cordigerum is a small plant with tiny, beautiful flowers. In Connecticut it did well in pots that were overwintered in the refrigerator as this species does not tolerate cold. Here in the Seattle area they do fairly well outside. I purchased a few to add to my breeding stock and am willing to sell two of them. Like Cyp californicum, macranthos rebunense and segawae, these plants were enormously expensive. Like those others the minimum order is 5. I was able to make some nice hybrids in the past, all with very beautiful flowers.


Cypripedium kentuckiense

Cypripedium kentuckiense
Blooming size plant
Sold Out
for PayPal click:

Cyp kentuckiense has the largest flowers of any Cypripedium species. Make sure to grow this species in fine sand with no organics. The perfect sand is Quikrete all purpose sand - the off-white to light brown colored sand. The very white sandbox sands are often extremely alkaline and will kill your plants very quickly.


Cypripedium macranthos hotei-atsumorianum

Cypripedium macranthos var hotei-atsumorianum
Blooming size plant
Sold Out
for PayPal click:

Cyp macranthos hotei-atsumorianum is loosely translated from the Japanese as "budha with a fat belly". It is not the easiest species to grow but easier than Cyp tibeticum. Do not allow ANY water to come in contact with the roots during winter thaws as the rhizome will rot. Curiously we find the hybrid between hotei and tibeticum to be much more tolerant of less than ideal conditions. It is called Eurasia (and is less expensive).


Cypripedium macranthos rebunense

Cypripedium macranthos var rebunense
Blooming size plant
Sold Out
for PayPal click:

Cyp macranthos rebunense is from the Japanese island of Rebun. It is considered to have holy status and going to view them in bloom is very popular. The population is protected by the Japanese army. About 10 or so years ago the Japanese government released seed to growers in an effort to make the species available to reduce poaching. I have had a couple of plants for a number of years and wanted to add diversity to my breeding stock. Anthura had them available this year (5 plant minimum of course) so I ordered some. I am willing to sell two.


Cypripedium parviflorum

Cypripedium segawae

Cypripedium segawae
Blooming size plant
Sold Out
for PayPal click:

Cyp segawae is a small plant with tiny flowers, similar in size to those of Cyp cordigerum. Like Cyp cordigerum, Cyp segawae does not like cold temperatures.


shanxiense

Cypripedium shanxiense
Blooming size plant
Sold Out
for PayPal click:

Cyp shanxiense is a small plant with small flowers. I have not had strong success with this species but in the past have received plants in top condition. Having said that, Tom Velardi, who has seen shanxiense growing in its native habitat suggested that I add some lime to its medium. I am going to try that. Shanxiense's hybrid Schoko is a hardy hybrid that has flowers colored nearly identicall to shanxiense.


   Hybrids

Please be aware that Cypripedium hybrids, like other hybrid plants that are not vegetatively produced, will vary in appearance of the plant and flower from specimen to specimen to reflect all of the possible gradations between one parent and another. Our photos are of actual plants in our garden. Yours may look similar or somewhat different.

Cypripedium Eurasia

Cypripedium Eurasia Frosch®

Sold Out
for PayPal click:

For a good alternate hybrid, see Cypripedium Henric below.


Eurasia is a hybrid of Cyp macranthos and tibeticum, registered by Nakamura in 2005. Eurasia has magnificient flowers. I really like these and hate to sell any. I have specimens spread around the landscape. Given that both parents are from areas in China with little organic material in their medium, we very strongly recommend that Eurasia be planted in a mix of turface and soil perfector, or in the western US, in a mixture of red volcanic gravel and turface. Make sure that during winter thaws there is no standing water since this will rapidly rot the rhizome and kill the plant.


Cypripedium Gabriela

Cypripedium Gabriela Frosch®

Sold Out
for PayPal click:


Gabriela is a hybrid of Cyp fasciolatum and kentuckiense, registered by Werner Frosch in 2003. Both parents are large robust plants with large flowers. Gabriela is easily as large a plant as any kentuckiense and have very large flowers similar in size to kentuckiense. It is a striking plant in bloom and I have been growing them since 2006. A real favorite and easy to keep happy.


Cypripedium Henric

Cypripedium Henric

Peter is a hybrid of Cyp macranthos speciosum and yunnanense, registered by Frosch in 2009. Peter is one of the earliest Cyp hybrids with uniformly intensely colored flowers. Like Eurasia above, make very sure to grow Peter in medium with no organics and make sure it does not find itself in standing water during winter thaws. The rhizome will rot very rapidly if it is wet during the winter.


Cypripedium rebunense x segawae

Cypripedium rebunense x segawae Frosch®

Sold Out
for PayPal click:


This is a hybrid of a plant (segawae) with tiny bright yellow flowers and a plant (macranthos rebunense) with very large cream-colored flowers. These plants were obtained from Frosch Exclusive Perennials and Michael had no photos of plants in bloom. I purchased a few for myself to see how they turn out. I have two that I can sell to adventurous types. Given the parents, it will be important for purchasers to be familiar with segawae hybrids, which tend to not like very cold winters.
