How to Buy Passiflora


Passiflora, better known as passion flowers, are flowering vines that are planted beside a trellis, wall, arbor or another support system. They make excellent garden plants with fragrant flowers that attract butterflies and hummingbirds. Some passiflora varieties are hardy to USDA plant hardiness zone 7, but most prefer warmer climates. In any climate, passifloras can be planted any time of the year; in zones 7 and 8, spring or fall planting is ideal.

Step 1

Locate your USDA planting zone by looking at a zone map, available in most gardening books, as well as on the National Arboretum website. Alternatively, conduct a zip code search on the Arbor Day Foundation website.

Step 2

Decide which passiflora variety you want to grow. It should be winter hardy in your zone, as well has have other characteristics you desire and planting needs you can provide. For example, Passiflora coccinea is fairly drought tolerant and grows well in most soil conditions. Passiflora incarnata is often considered the "showiest" because it blooms more flowers than other passifloras. Passiflora foetida, on the other hand, is very easy to grow, but can become invasive if not pruned.

Step 3

Calculate how many passifloras you need to buy. Passiflora is spaced 3 to 5 feet apart from one another and will fill in a space in one or two years.

Step 4

Buy passiflora from a nursery. If you live in zones 7 and 8, you may have to travel south to find them for sale. Look for plants that appear to have healthy green leaves and strong, healthy stems. Alternatively, order passiflora from a reputable online nursery.
