Gardeners' Notes:


On Sep 4, 2015, Grow1 from Tallahassee, FL (Zone 8b) wrote:

It is common at the edges of wooded lots in Tallahassee. It climbs up and around other plants and it is sometimes difficult to see the foliage of Centrosema because the leaves tend to hide in the leaves of the plant it is climbing. Sometimes it is seen growing by itself and not climbing another plant, but that is much less common.

What kind of Butterfly Pea do you have? Info from wildflowers.com
Clitoria Mariana is known by some as “Butterfly Pea”, and Centrosema virginianum as “Spurred Butterfly Pea.” The 2 Native American flowering vines are easily confused. A spur is found at the base of the petals of Centrosema. Another key characteristic that can help is the relative length of the corolla tube. Clitoria mariana has a long visible corolla tube – usually as long or longer than the keel and wing petals. Centrosema virginianum, on the other hand, has a short corolla tube that is generally invisible as you look at the frontside of the blossom.

I found this growing throughout our ivy in our front yard. It is really a beautiful vine. I am learning more about how to move it because I would like to see if it will climb. I have tons of it.

I started my seeds, which were a gift from a DG-er, by gently nicking & soaking overnight in warm water, then wrapping in a moist napkin and putting in a ziploc bag until they sprouted, then planting in potting soil. They are up now & quite delicate & enchanting. I have read everybody's post & will keep them potted but I might repot them in 1/2 sand & 1/2 potting soil. The pictures remind me of Clitoriana mariana, but I remember I did collect seeds from that plant in Central Va so this might be Clitoria mariana. I'll take a pix of the seedlings for you for correct identification. Either way, either plant is enchanting and I hope I can grow them to blooming size.

I live in SE Georgia. I found this vine growing in a partially shaded area in gravel. This area is very dry. The soil is several inches below the gravel so it must be a tough plant. The leaves on mine are more elongated and narrow than those pictured on this site.

Pretty little wild flower found growing throughout NE Florida. I'll find these plants frequently along roadsides or in shaded areas of the woods, though sometimes growing up a fence in part-sun. Seems to like damp places. I love stumbling across these on my walks through the woods.

This pretty vine is native to my east TX woods. I found the seeds a bit difficult to start. After soaking in water for a period of time, I was able to start a few from seed. The Butterfly Pea vine is a perennial in this zone. It will do well in ground or in a container.

I had never seen nor heard of this plant and found it growing wild in my shade garden..must love the filtered light and moisture there...Jeanne

I love this vine, the flowers are so pretty but the foliage does not make a statement. I agree it should be planted with other vines, letting the flowers make the impression.

Some additional Info that I found on this plant:
It is listed as a perennial although I have not had it return for me in zone 9. I always have to replant. It is SAID to be hardy to zone 6. It is in flower from July to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by bees. (my carpenter bees LOVE them) It can also fix Nitrogen.
It prefers light (sandy) and medium (loamy) well-drained soil and tolerates poor soil. It prefers acid, neutral and basic (alkaline) soils and can grow in very acid soil. It cannot handle shade. It requires dry or moi... read more

I agree with bonjule about planting this with other vines.
The foliage is inconspicuous but the blooms will be outstanding against the foliage of another vine. Maudie

In Florida, I saw painted lady butterflies using this plant for nectar. Where it is allowed to climb on another plant, it excels.

A slender trailing or clasping vine with purple flattened pea flowers (3/4 - 1 1/2") with a small spur at the base, single or in small clusters. The flat part of the flower is pointing groundward unlike most of the pea-family. The leaves are alternate, divided into 3 leaflets ovate to lanceolate, each 1 - 2 1/2" long.
Flowers July-August. Likes open, usually dry, woodlands and fields, pine forest edges.
