"Registered in 1914, Paph. Julius is a most distinctive and heavily-awarded primary hybrid that still remains enormously popular with the paph connoisseur. Like so many of the primary rothschildianum crosses, Paph. Julius combines the best features of both parents. Paph. lowii contributes the wonderful pink coloration, and Paph. rothschildianum bestows the boldly-striped dorsal sepal and overall size & stature. Paph. Julius is an easy grower under warm and bright conditions, and mature plants typically produce 4-5 flowers per inflorescence that may each reach 10-12" in natural spread.

Paphiopedilum Julius is a hybrid from the genus paphiopedilum.

Keep plants moderately lighted or partially shaded with humidity at 60 to 85% with an intermediate night temperatures of 58°F to 62°F and day temperatures of 75°F to 83°F. 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 in depth flower color grow in shade.

A tip I would give to new growers here is not to make the same mistake I made when potting up this Julius. It had such a big root system that I couldn't see any bark. Nothing but roots. So I just repotted it up into a bigger pot and filled bark around it. Over time my beautiful healthy rootball completely rotted. It really set my plant back and took me another 5 years to flower it and will take a few more years to get back to where it was. When you find a root system like that you need to tease the roots apart and remove all the bark. Even if it means getting a hacksaw and cutting the roots, this is better than doing nothing at all. When the roots are all wrapping around each other and are tightly packed you need to separate them so that air can get all around. This can take a lot of time. A large plant can take me 2 to 3 hours to repot as I try to damage the roots as little as possible.

Bloom Season:








This is a superb cross producing tall stems of usually 3-4 flowers that can reach 10" in breadth. It is an easy plant to grow and very reliable about reblooming every year.


Medium light - somewhere between the requirements for a Phalaenopsis and Cattleya is best. On the window sill - East is best, or south with mini-blinds or a sheer curtain to break up the sunlight.


50 - 70% is ideal.


This plant will tolerate municipal water with a pH of 7.5 or less. It also grows well with rain, distilled or reverse osmosis water. Water as the plant approaches dryness, but do not allow it to become bone dry.


If you use rain, distilled, or reverse osmosis water, we recommend adding calcium and magnesium in a fertilizer such as CalMag 15-5-15. With municipal water or water with higher pH, use GrowMore 20-10-20 Ureafree. Either one should be used at the rate of one teaspoon per gallon of water.



This plant typically blooms in the spring months in the northern hemisphere (Feb - June). When the sheaths appear in the center of the growths, keep the plant more evenly moist to ensure proper spike and bud development. To keep the flower color deep and to prevent fading, move the plant to shadier conditions after the flowers have opened.


Utilize a medium fir bark mix (Rexius is best as it is a sterilized bark). The best time of year to repot is generally just after flowering when the new growth is made up.

Springwater Orchids scored an HCC (77 points) at the Redlands International Orchid Festival on 13 May 2010.  Photo can be found here.


In 2010, Dale Martin scored a CCE (Score: 90 points) and that photo can be found here.


EDITOR"S NOTE:  I have seen the parents of the hybrid cross Paph. Julius listed as both (lowii x rothschildianum) or (rothschildianum x lowii) on many websites for vendors, forums and even AOS award web pages.  It is my understanding, that the progeny of (lowii x rothschildianum) is different than that of (rothschildianum x lowii).
