Seed of the Week: Passion Vine

Our dimpled mystery seeds from last week…

… are from a plant with a beautiful and unusual flower.

Do you recognize it now? The plant is called passion flower or passion vine, Passiflora sp.

There are some 500 different species in the genus Passiflora, and many new hybrids and varieties being generated all the time.

This species is the Mexican passion vine, Passiflora mexicana. It is native to Arizona.

The Mexican passion vine has a bilobed leaf, which means it has two lobes.

Leaves of other species may have many lobes. The lobes may even be unequal in size, like a mitten with two or more thumbs like the species below.

See all the partially eaten leaves? Do you see the culprit?

Here’s a closer view. The caterpillars of the Gulf Fritillary butterfly feed on passion vines. If you are growing a butterfly garden, you will be sure to enjoy the colorful caterpillars and the butterflies they turn into. If you are mostly interested in the flowers, however, you may be dismayed because these caterpillars can defoliate a plant.

Just remember that in order to for the plant to produce fruit, it needs to be pollinated, and butterflies are important pollinators.

Beetles can be, too.

You might want to visit the link to see some absolutely jaw-dropping macro photographs of a Passiflora hybrid, with a lot of detailed information about the flower structures.

Aren’t those photographs amazing?

Mystery Seed of the Week 126

If you have ever seen these seeds up close before, you will recognize them right away.

The surface is loaded with pits or dimples.

Any idea what plant produces these dimpled seeds? Be sure to leave a comment if you have an idea.

Please don’t be embarrassed if your guess isn’t correct. It is very difficult to tell from a close-up photograph with no scale.  I appreciate guesses because it gives me ideas for future posts 🙂

Edit:  The answer is now posted.

Seed of the Week: Yellow Oleander

Our mystery fruit/seeds from last week were from a yellow oleander, Thevetia peruviana.

Yellow oleander is named for its bright yellow flowers (although some varieties have light orange flowers).

Yellow oleander is originally from tropical regions of Central and South America, but now is grown throughout the world. Being tropical, it is quite frost sensitive. Here in the Sonoran Desert it is often used in landscapes next to houses or walls, which radiate heat. It is grown as a tall shrub or small tree.

The trees are evergreen and flower over an extended period.

The down side to these plant is that yellow oleanders are toxic. All parts are poisonous if eaten, and the sap can irritate the skin in sensitive people.

Even the seeds within these oddly-shaped seed capsules are poisonous.

The seed capsules are hard and have a raised area or ridge that is often apparent even when they are fresh and green.

Do yellow oleander grow where you live?
