Hailing from South America, Passifloras entertain dazzling flower parts that attract butterflies and plant lovers, and in the Catholic faith once symbolized Jesus’ last day. These wildly vivacious and floriferous semievergreen climbers appreciate sun, heat and good air circulation as well as cold protection around 18 degrees plus free-draining, somewhat dry sandy soil with moderate fertility. Frequent trimming will encourage branching, while a cool greenhouse or warm masonry wall will ensure their winter survival.
Named for his mother, this Passiflora ‘Clear Sky’ x Passiflora loefgrenii ‘Iporanga’ cross was made by Passiflora aficionado Myles Irvine in 2005. Unleashed against hearty dark green lobed leaves and winding tendrils, astonishing quantities of 30 or 40 slightly reflexed, 3 to 4 in. wide dusky purple flowers appear each day. Maroon and green centers coupled with striking slender pointed filaments, each sporting a smoky blue tip, white halo and a dark midnight blue base embellish the stylish lightly scented blooms. Considered by many to be the foremost garden-worthy Passiflora currently available, ‘Betty Myles Young’ is a robust polyploid hybrid that lends a winsome glossy presence to trellises, protected walls or containers.

Perhaps the only yellow blooming hummingbird pollinated Passiflora in the world, this exquisite freeflowering climber can be relished inside or out. Dozens of bright lemon-colored starry blossoms festoon an easy-to-manage, highly welcome diminutive stature that's draped with small bilobed evergreen leaves. Sauntering around Guatemala and Honduras, where John MacDougal first spotted it in 1989, Passiflora citrina is a stellar contender for containers, sun-basked windowsills, hanging baskets and tight garden spots. Bright light, average moisture, almost any moderately fertile soil and night temperatures exceeding 25° keep the flowers coming. Medium Band.
