Passionflower
(Passiflora sp.)

The fascinating blooms of passionflower are absolutely beautiful and are best viewed up close. Few flowers can match them for intricate beauty. Their vigorous vines grow to 20 feet or more, and are best suited to a fence or trellis where the blooms can be best appreciated. Commonly available in blue and purple flowered forms a red tropical form (Passiflora coccinea) is also available. Some are perennial while others are not dependably winter hardy. Passionflowers bloom best in a sunny location although some afternoon shade is fine. Provide a soil with plenty of compost mixed in and provide moderate moisture levels. Fertilize periodically to maintain good vigor. Passionflower leaves are a food source for Gulf Fritillary caterpillars, and are a must for your central Texas butterfly garden.
