Passiflora citrina is a cute passiflora vine. It’s relatively small, and though you can really grow it out (it’s a rapid grower), you can easily maintain it small and compact. The leaves have an interesting shape to them and have yellow stripes.

The plat looks it’s best when you get the foliage dark and luscious, since the flowers are yellow. If there is not enough light, or the soil is not rich enough, the leaves will get lighter and yellower, and though you will still get plenty of flowers, they won’t be very noticeable.
For best results, besides giving plenty of warmth, light, and fertilizer you can even add slow release iron supplement to the soil to get the leaves dark enough.

The flowers are not as large and showy as other passionflowers. They are solid yellow and look like numerous stars on the passionflower vine. Before they open and after they close, they look like yellow candles, and are still decorative (each passion flower opens for only a day). They are freely produced year round and are a joy to look at!

Passiflora citrina originates from Central America, and can tolerate lower temperatures for short periods of time. When grown as a house plant, it’s evergreen and everblooming. This passionflower is small and compact, very easy to take care of, and very forgiving of neglect. And given suitable conditions it will constantly bear flowers. Though the flowers are not big and showy, they are lovely to look at and so numerous, when the plant is grow well, that it’s quite a sight.

Requirements:

Watering needs:

Passiflora citrina has medium watering needs. In my experience it handles drying out and over watering quite well. When the plant is dried out it seems to drop leaves instead of wilting, and when overwatered the leaves get paler and the soil gets washed off from nutrients. Overall a very forgiving plant. Water generously when the soil feels dry to the touch and use a well draining medium for best results.

Light:

In my experience Passiflora citrina prefers part shade over full sun. You can grow it on east/south or west window inside, but if taking it outside for the summer, it will prefer part shade. This plant will flower with lower light level as well, but it will not do well on a north window.

Humidity:

Passilora citrina is not as fussy s other passionflowers, and can tolerate lower humidity levels quite well. It’s also quite resistant to bugs. When the humidity is really low, the leaves become more brittle, so for best results keep the humidity higher.

Soil Type and Fertilizer:

Rich well draining medium is perfect for this plant. You can use a generic potting mix with slow release fertilizer and some sand or per-lite. I like to add a bit of compost to my mixture, and it seems to give the extra richness to the soil. Generic fertilizer will do just fine. I would say this plant is a moderate feeder, though not as much as some of the more showy passifloras, so be careful not to over-fertilize.

Propagation:

Just like other passifloras, Passiflora citrina is very easy to propagate through cuttings. I’ve successfully rooted cutting any time of the year and any type of cutting would work. The plant grows rapidly, and reaches blooming size in half a year or less depending on the conditions.

Other Care Tips and Personal Observations: 

As a rapid growing vine, this plant requires support. Feel free to cut back loose growth and wrap the plant and shape it however you like.

To have a nice dark foliage it helps to add a bit of slow release iron granules to the soil, and ensure the plant is getting plenty of light.

Passiflora citrina doesn’t require as much light as other passionflowers, and can be grown successfully at lower light levels, as well as under grow lights (daylgiht LED works just fine if you provide enough lux to the plant).

Very easy plant to grow, and a generous bloomer, this passiflora makes  a wonderful houseplant!

Passiflora periesii is one of the many wonderful everblooming passiflora varieties. They all more or less require the same conditions, though some are more needy than others.

Passiflora periesii is a large showy passiflora. The flowers only last a day and they tend to open consecutively along the stem. When your plant gets large enough, it will be continuously covered with flowers.

The higher the light/heat/humidity/soil richness the more you will get out of your plant. This plant requires room and support to climb on. Extremely showy and very rewarding to grow. Even thought each flower last a day, it makes such a beautiful sight to see. The flowers are such an intense bright red color, they almost seem to glow. They are also very large and look almost unreal.

Requirements:

Watering needs:

Water when the plant when the soil approaches dryness. If the temperatures are high, water the plant more generously. Passionflowers generally like a lot of sun, heat, water, fertilizer and humidity. Pretty much a lot of everything. During the winter reduce the amount of water appropriately.

You can find more information and tips on watering here.

Light:

The more the better! Passiflora piresii will flower on an east or west window, but it will do the best on a south facing window. The picture on the right shows Passiflora piressi flowering on a small east facing window. If you have the opportunity, grow it outside in full sun during the warmer months.  Supplementing it with grow lights during the winter will help to get more growth and flowers during these dark times. If I had southeast floor to ceiling corner windows (the next best thing after an actual greenhouse) I would have tons of ever blooming passionflowers!

Humidity:

This plant prefers higher humidity, though will tolerate lower as well. If the humidity is too low the corners of the leaves will dry up, and the flower buds may fail to open.

Soil Type and Fertilizer:

Passionflowers like rich soil mixes, neutral to slightly acidic, that are freely draining. Some varieties can tolerate a wide range of soil conditions, others are more fussy. When I re-pot my passifloras in the spring I like to mix in general potting mix with some peat moss and a bit of fully composted cow manure to get the pH slightly up and add plenty of organic richness to the soil. I also add perlite or sand to insure the soil is freely draining. Generic fertilizer applied at half strength regularly throughout the growing season seems to do the job. If the plant leaves turn paler, the plant is either not getting enough nutrient, not enough light, or is missing minerals.

Propagation:

Can be easily propagated though cuttings or seeds. Cuttings is preferable as the plant will come  into flower as soon as it gets big enough. If you grow your plant from seeds it may be years before your plant matures enough to start flowering.

Other Care Tips and Personal Observations: 

This is a large leafed vine with big flowers that requires quite a bit of support. Shaping pruning and wrapping back onto the trellis is essential to keep this plant in a good shape, well branched and looking good.

The higher the light the better. It’s interesting how the plant forms buds up along the branches in a way that would allow the flowers to open one a day. The leaves are big and darker green, beautifully contrasting the flowers. Passiflora piresii flowers don’t have a sent.
