This is a very lovely thing even though the flowers are individually very short lived. Their appearance is always something of a surprise, because one day there's no sign of any flower spikes and then they suddenly emerge. The flowers sit well above their bracts and are on pedicels that are longer than other species, which means that many so-called 'gracilis' are probably either candida or northiana. No matter, they're all very attractive and worth growing.
The glossy, apple green leaf fans always look fresh and purposeful so a well-established plant allowed to develop offsets fully on the old inflorescences can look magnificent in a large hanging planter. If you've ever seen an old variegated 'spider plant' (Chlorophytum comosum) looking resplendent trailing from a large hanging basket, you'll understand what I'm getting at.
The 'Apostle' bit in the common name is somewhat misleading because a strong, healthy, vigorous plant will produce flower spikes from fans that have fewer than 13 leaves. I have several plants with flower spikes on 5/6 leaved fans as well as the larger ones.
i'm so glad to have finally found out what this plant is for sure. i got it from a planter in a bank i worked at in south central pennsylvania close to 15 years ago and have never known for sure what it was till now. it is an easy grower and blooms beautifully. however, my plant has a bug that feeds on the roots and that will quickly kill it. it's been struggling for several years and i'm stressing badly because i don't want to lose it. can anyone give me any tips on how to get rid of the bugs? i have repeatedly repotted it with new soil and pot. sprayed the foliage and roots...before it had bugs it was huge. i haven't tried planting it outside (in southwest ohio) in the pot it didn't do well outside, so i keep it in. any suggestions to get rid of the bugs would be very welcome. i'm open to about anything at this point.

I bought this plant last fall from a nursery in Naples, FL and am growing it in a clay pot on our 11th floor west-facing veranda in Sarasota. It bloomed for the first time two days ago, and I was thrilled! Luckily, we were at home to see the blooms and take pictures. The tips of the leaves get a little brown (maybe too much sun, but I have no choice about that), so I trim them off and the plant seems to thrive anyway. My husband -- the gardener in the family -- is itching to divide the plant, but so far I've kept him at bay. Once it stops blooming, I'll turn him loose on it and share the babies with other veranda gardening friends. What a terrific plant!

Tough plant! Easy to grow. Mine are descended from Hurricane Katrina survivor plants at my relatives' house in Bay St. Louis, MS, west of Gulfport, MS. The ancestor of my irises was under water for at least several hours during the storm surge (their hardwood floor had to be replaced due to flood damage). Mine get some sun/some shade in my patio and overwinter just fine in Central Louisiana 8b. I just uploaded a picture of 3 blossoms taken 5/7/09. I should have babies to trade about 1-2 months from above date. Tell me if anyone wants one; it's too early to put them on a trade list as I have to grow each plant from a blossom.

This plant really takes care of itself. Mine flowers every year, and from those offsets I make another pot. My parent plant is about 3 to 4 feet around and 4 feet to tip from the bottom of its basket. It trails up to 5 feet. It hangs in my gazebo in full shade in the summer and winters in our small greenhouse. I grew up calling this plant a trailing iris.

HELP! This is one of my favorite plants. WIs are located in two separate full sun areas of my garden. They've grown profusely over the 2 years since being planted and have become over crowded. They are not flowering as they did when first planted even though I have a professional company fertilizing. I do remove pups occasionally and pass them on to friends. I need your help in how to get more blooms and rid the existing plants of the "scruffy" green (tops yellowish/brown) foliage. I noticed in one of the pictures the tops of the plants were cut back. Is this what I need to do? Thanks, St. Petersburg, FL
My great grandmother had the origiinal plant and she's been dead about 35 years. When my grandmother gave up housekeeping I took the plant. I have been rooting and dividing the plant for over 5 years. It just continues to grow in full sun or partial shade, however the foliage seems to be greener if grown in partial sun. Every year I root new plants and give them to friends and family as a gift. It's always well-accepted since it appears to be rare.

We live in Hope Town, Abaco, Bahamas and the Walking Iris is one of our favorites! It gets a bit brown when there is not rain (we have no ground water, only what we catch--so no irrigation here!) But in the summer, spring & fall it blooms constantly & puts out so many new plants that we can share often with neighbors. Lovely in the light breezes as it sways & nods it's yellow head.

I have this plant growing in the ground in shade under a large oak. It dies back after a frost, but comes back as soon as it warms up. I also have it in a hanging basket under a tree, but I put the pot in the hothouse during the winter. It does very well for me and I love the flowers.
I've grown this plant for the past 30 years. I even put several hanging baskets on crates in a part of my back yard that wouldn't grow grass because of the shade and they dropped shoots and rooted in the ground and eventually took over that part of the yard. I originally protected them completely in winter in a greenhouse but a few years ago noticed that an ice storm we had had no effect on several plants in the flower bed that had been unprotected for three days of ice. Now I consider them the heartiest plants I own and don't worry about them at all.
This plant has been in my family for 30+ years. My grandmother brought in from the family farm in the Hinton/Anstead area of West Virginia. She always called it an orchid. I inherited this plant 18 years ago & was just able to get it identified recently. It is still in the same pot that my mother had it in for many years. We have always had it as a house plant. I never fertilize it & only water it once every 1 to 1 1/2 weeks. I keep it in a window that gets the morning sun with sheer curtains filtering the light. It usually blooms around Mother's Day but this year it bloomed again in July & August. The pups are super easy to start. Just cut off & strip the runner off so the roots are exposed & put in water. It starts rooting within just a couple of days.

I just recently (Dec. '05) divided my N. gracilis which had been in the same 3 gallon container for almost 20 years. I was forced to use a hand ax in order to separate the root system into 8 individual "starts". Happy to report that all are doing well. In addition, I have several other mature plants which have been in the ground for almost seven years and I have divided these periodically for many other people in the area. It is simply a great, minimum-fuss plant in coastal South Carolina. (docturf)

I was given a single one of these plants about 8 years ago, and it multiplied into dozens by the time I moved from my previous home 6 years ago. I brought a few with me to my present home, and now have innumerable plants all over my yard! They are great, and do excellent in partial-sun / partial-shade areas. (The ones that are in full sun tend to turn yellow).
I have given many of these away, and in fact just gave away 24 plants to all the students, professor, & guest speaker in the last class of my final college course. Have helped to re-do a few homes, and have always used these in the landscaping as well.
Before reading the comments above, it never dawned on me that this might make an excellent hanging-basket plant, and so I've just planted some in a hanging basket this weekend.
I'm now searching for some of the closely-related yellow variety (Neomarica longifolia), which a classmate has graciously offered to share with me.

I live in zone 9 and have had great success with these plants. The rate in which they mulitiply is very good. Always new ones to spread around. I use them in large planters with large night blooming cactus for a dramatic show. The plants stay green year round, have been drought tolerant and untouched even during cold snaps. I fertilize them regularly and keep their soil on the moist side. My only complaint is that each beautiful bloom lasts only one day and they are somewhat fragile as rain drops can spoil their look easily. I have allowed many plants to naturalize an area under a ficus tree and they seem quite happy in dappled shade. My mother in law keeps the ones I gave her in a sunny window inside her home and has had great success with getting them to bloom and produce new plants she too can share. We simply wait for the new plant to grow from the spent bloom area and break it off and stick it one and a half inch intoa four inch pot filled with Miracle Gro potting mix and keep the soil moist. In no time at all, the new plant will take root. When naturalizing, the new plant should be allowed to touch the soil to take root. Mulch should be pushed back around the area where your new plants wants to lay.

It took my breath away it was so beautiful!
I grabbed my camera to take some pictures to share. I am glad I did, because the bloom lasted only a day. This is an easy to care for plant, but make sure you are around to see it on the day it blooms! You don't want to miss it.

Can't believe there has been no mention of one of the really beautiful characteristics about this plant! The flowers open early in the a.m. and do last for only one day. But if you watch carefully, you can tell when they are ready and actually watch the petals unfold -- just like time-lapse photography. I was interested to read about the bee triggering the reverse action -- have to watch for that. Great plant to show the kids.
Mine is a real heirloom plant, originally acquired from a lady in Savannah, GA, who had it from her mother and/or grandmother. I passed it on here to friends and recently got one back when I lost mine during house moving.

I brought one baby apostle from Maryland to San Diego, put it in a pot and it has grown into a large beautiful plant. I get many babies and flowers each year. The flowers have a soft sweet smell though short lived and will bloom up to 6-7 times with each new apostle baby. Living along the coast allows the plant to stay outside year round. I was told that the original plant my apostle came from, was in the Pennsylvania woods... growing wild. This plant is pretty much unknown in San Diego.

Nice together as they are quite different with the leaves of the yellow very upright and a lighter green while the blue's leaves are more glossy and curve in an arc. the yellows are more hardy and bloom year round while my blue bloom mainly sprin/summer.
A friend of mine gave me a couple of small plants 2 years ago and I planted them in some metal pails and put them under a tree in my front yard. They get good morning sun and it is filtered the rest of the day. Last year, I saw one bud in the morning and by the time I got home from work, it had already bloomed and I missed it! My blooms only last one day, so I have to pay attention or I don't get to enjoy them. This year, I've had about 20 blooms on one plant and they keep coming. I've now got some babies that are growing from the bloom sites, so I'll have to cut them off and grow some more! This is truly a GORGEOUS plant. I think it looks a bit like a cross between an iris and an orchid. Just beautiful. They are so easy to care for, too. Just a bit of water once a week or so, I never fertilize, and they grow like crazy! (Even when it's 95+ degrees outside.)
finally I found out the name of this unique plant. found it on EBay of all places. It did real well for me until I had to bring it in the house. Now it looks like it is on its last legs. there are still some green leaves left but it started out losing its color then dead dead leaves. I am hoping it will come back to its full glory. Anybody have any ideas on what's with this plant. It is is a pot now outside but shows no signs of new growth.

I grow mine in Orchid compost with added grit (the same as on the bottom of a bird cage), and in 15cm clay pots, I water little and often, only useing rain water, as I have found the chemicals in tap water is oftern , not harmful , but the plants dont like them. I spray dilute food, maybe 1ns a week, and tomato feed, as soon as the flower stem starts to appear. This ensures a good healthy flower, and hence , a new healthy plant,, I spray baby plants, not water as I have found this tends to rot them. So now I have joined you, happy band of Apostle growers, (my plants are the Candida.)

This plant is pulling me out of poverty! I made over $300.00 in one week just before Christmas! My Grandmother passed away in 1994, and I was the only family member who wanted them. I had no idea what type of plant it was until May of 2003. At this time I have over 300 adult plants and about 150 off-set "pup" plants. They do not require very much fertilization, but I have read they like a "light" acidic soil. I have never had this plant NOT bloom from early Spring into Mid-Summer. They like their soil moist at all times and prefer shady places to filtered sun. Morning sun is best, especially if your zone has hot Summer temperatures. This use to be a pass-a-long plant years ago, and although not a rare plant, it is hard to find one in a nursery. They are a rhizome Brazilian Iris and can be planted in the landscape in zone 9 and above. Plant in grassey clumps and do not mulch, or the rhizome roots can rot. Well drained organic soil is best for this Iris.

I'm glad to find out here the name of a plant I grew for years in St. Petersburg, Florida. I acquired the plant at a plant raffle...simply labeled "Walking Iris". I planted it under a very large laurel oak, along with azaleas, liriope, ferns, and syngonium vines climbing up the oak--this was a very shady spot. After a few years this plant pretty much took over the bed, and I had to dig out almost all the babies and pot them up. They sold great at periodic yard sales! The lovely, small, white and deep-lavender flowers only lasted a day, but there were lots of them. This bed had a lot of humus due to all of the falling oak leaves.

If you like blue and white accent in the shade, this is your plant. It may need more sun farther north, but in central Florida, it seems to prefer medium to dense shade. My potted one is not as happy as it will be when I release it into the garden. At my old house (40 miles away) it had gone nuts under the big maple, in the remains of a log. As with most woodland plants, this one adores lots of organic matter, and that's about all the fertilizer it really needs. The dark green leaves are glossy and very pleasing. It is a wonderful accent among ferns.

I love this plant! It blooms best when pot bound. I keep them in pots and in the shade. It seems to be able to take lots of water or low water. I can't seem to kill it. In Louisiana weather that is a definite plus. The blooms last one day and every bloom will make a new plant. When the new roots start showing (about 2 months after blooming), pot and cut it from the mother plant. I have a six year old plant that has over 50 blooms a season. The dark green foliage is lovely. Watch a bumblebee as it lands on the purple petals. As the bee walks up the petal, the petal curls inward and propels the bee to the center of the flower for nectar. Fascinating! This is a great pass-along plant.

It´s not hard to control, though. And the flowers, in the summer, are wonderful. It lives specially well in coastal areas.

Walking iris, Neomarica gracilis, is one of the Neomarica species, other well-known species are N. caeruela and N. vittata.
In Finland we call it Apostolinmiekka, or Apostolinkukka, which means Apostles' Sword, or Apostles' Flower. When the plant has 12 or 13 leaves, the leaves are the disciples, and then Jesus rises in the middle of the plant (the flower). In Sweden it has also been called trettonblad (thirteen leaves) because it usually blooms when it has 12-13 leaves.
After flowering plant produces a little plant to the place of the flower.
