Paphiopedilum Leeanum is a hybrid between Paphiopedilum spicerianum × Paphiopedilum insigne.
Keep plants moderately lighted or partially shaded with humidity at 60 to 85% with an intermediate night temperatures of 58F to 62F and day temperatures of 75F to 83F. To induce blooming, with hold watering and maintain a cool temperature, ie. 55F during winter nights and expose plant to 9-12 hours of good lighting every day in the winter. plant grow well in bright light; however to get more indeph flower color grow in shade.

Easy Orchids – Paphiopedilum Leeanum
This plant is an orchid classic – a very old primary hybrid raised in Britain in 1884, when the first hybrids were appearing among the orchids. From the start, these handsome slipper orchids were in the forefront of his new hybridizing and were among the most popular with the (mostly gentlemen) growers of that time. The parents of this lovely hybrid are P. insigne and P. spicerianum, two of the most popular orchids of their time, and even today they are both considered to be collectibles. Once extremely plentiful, they are now rare in collections, as is the hybrid from them. This plant exhibits all the grace and classic lines of the species. It should be grown in cool, shady conditions and blooms in the winter. The single blooms will last for eight weeks or more.

This is a primary hybrid between Paph. spicerianum and Paph. insigne. It is a very hardy plant.
Honestly, I've never seen anything like that with Paphios. And because it is hardy, people here plant it everywhere. It seems to me that it grows wherever you plant it. If you blink, it end up growing even on the asphaltic road floor !!! It is so common that orchid collectors don’t give a dime for it.
I once gave a single fan to my mom recommending that she planted it using tree fern fiber. She forgot about the tree fern fiber and planted it in a large pot filled with pure earth. A few years later I asked her about the lady slipper orchid I had given her and she said: 'Oh, it's flowering now, go see it in the backyard'. I couldn't believe in what I saw! Twenty-six floral stems, half of them with two flowers and two of them with three - believe it or not!! - three perfectly formed flowers! I had the same plant (hers was a piece of mine) grown the standard way and never, never got more than a moderate number of flowers and always one per stem!

The slipper parade continues, it is Paphiopedilum season after all. Let me present Paphiopedilum Leeanum, a lovely primary hybrid with Paphiopedilum insigne as the seed parent and Paphiopedilum spicerianum as the pollen contributor. It is an old classic as far as hybrids go, registered in Britain in back in 1884 when the orchid hybridization craze was first gaining momentum. Leeanum was one of the first of many successful insigne crosses exhibiting enormous vitality and eagerness to bloom, a quality making insigne very popular in hybridization programs. Once plentiful in cultivation Leeanum is now a bit more scarce even though I feel it is making a bit of a comeback.
Arguably there was no need to improve on the original species in this case, but I think this cross still holds merit as it has inherited all the best from both its parents. The grace and classic lines are still there but the flower is a tad larger and more flamboyant. Having lost a smidgen of the insigne graphic pattern in the sail enough remain to make a statement along with the amazing shape the spicerianum sail adds to the party. Leeanum usually blooms in the winter and the flower has some nice staying power, usually lasting a couple of months or more. It does not requite a whole lot of light and is pretty easy to grow, but with two intermediate growing parents it should be grown as such. I water pretty evenly year round, only slightly drier for a few months right after it is done flowering in the winter. Since both parents are calcareous I add a little crushed sea shells to the potting mix of medium bark and small leca.
