The Beauty of Vines

Growing vines can be addictive. They’re instantly satisfying to an inpatient gardener, as some of them can grow to monstrous sizes in just months. I’ve been reticent to grow vines until I’m sure I won’t be spending my days getting rid of their seedlings (see my woes on the trumpet vine below), but I have so many fences, bare walls, and things just in need of green and lushness. I just love how quickly vines grow and cover a wall, a trellis, a fence… instant green, instant color (and sometimes, as in the case of sweet peas, loads of flowers to pick and bring inside!).

My love of vines means that I have to constantly come up with places for them to grow, and I’ve become an avid collector of bamboo poles, free-standing trellises and willow structures. Some of these structures become garden art on their own, and it’s fun figuring how how best to show off certain vines and create sculptural pieces with them.

Up to this point, many of the vines I’ve tried are annual or borderline perennial (either tropical or from a warmer climate than ours). My tropical Mandevilla vine, for instance, needs to be protected in the winter, or else it will die back, but is one of the few things blooming in the dead of August. Many passionflower vines are also tender here, and usually die back but come back with a vengeance in the summer–particularly the Passiflora incarnata, an elaborately-flowered Texas native.

The main monster vine that I am currently battling in my garden is called Trumpet Vine here, also known as Campsis radicans. Although it’s a native Texan, fast-growing, and hummingbirds and butterflies love it, its root system is so deep and its tendency to spread everywhere you don’t want it so annoying, that it’s the only plant I resorted to poisoning (although I feel a little bit guilty about it), since all my cutting, chopping and attempts to digging out came to nothing. Many unsuspecting Texan gardeners plant this only to join the crowd of people trying to find a way to rid their gardens of it a few years later. Unfortunately, I inherited mine with my property, and some of them now have stalks the size of tree trunks.

Passionflower
Since I wanted something else other than my ubiquitous trumpet vine, which is growing up through my pecan trees, over every fence, over my barn. I introduced a a nearby passionflower (Passiflora incarnata, popularly known as Maypop) to compete with it. And, yes, although this passionflower, native to Texas, is also known to reproduce and self-sow prolifically, it’s flowers are ridiculously beautiful and complex, and it’s covered with butterflies from April to October.

There are a number of other popular passionflowers you can grow here–I’ve tried the fruit-growing Passiflora edulis, which is pretty although its flowers are a little smaller and less glamorous and it kept getting eaten to death by the Gulf Fritillary caterpillars. And many can be grown for their fruit, but so far Passiflora incarnata is my favorite.

Passionflowers are sometimes grown as annuals, but usually they make it through the winter here so I consider it a perennial.

Morning Glory
I’m fairly new to growing these annual summer vines. According to some of my research they are considered invasive in some parts of the U.S. but our hotter climate keeps them from spreading as much. They are usually sown from seed in April, directly outdoors where you want them. Like many other summer vines, the seeds can rot if they are planted in too cool of a soil.

Morning glories are a romantic old-fashioned climber, have been grown in Texas since the frontier days, and are usually the vine one thinks of climbing over fences in cottage gardens. The large flowers open in the morning. Species of Morning Glories are Ipomoea purpurea, which includes Grandpa Ott’s, probably the most famous historic Morning Glory, and Ipomoea tricolor, which includes Pearly Gates and Heavenly Blue, also heirloom varieties. I have seen these covering entire fences in Austin.

Moonflower (Ipomoea alba)
A relative of Morning Glory, moonflowers open in the evening and are deliciously fragrant. I’m planting these alongside the Morning Glories to have both morning and evening flowers. With both Morning Glories and Moonflowers, chip or soak the seeds overnight to hasten their germination.

Update November 1, 2008: while the Morning Glories struggled in our summer, the Moonflower held on and this week finally rewarded me with blooms. They are enormous, nearly 8 inches across, and waft a powdery sweet scent more noticeable at night. I have these planted on an obelisk near white Abyssinian gladiolus, which smells very similar and blooms in late October.

Cypress Vine (Ipomoea quamoclit) – another relative of Morning Glory, these annual vines have lacy bright green foliage that looks gorgeous against more stout looking plants. I first got the idea for planting these after seeing them intertwined with a Maypop passionflower on a neighbor’s fence. They self-sow like crazy and the bane of some gardeners so it’s worth weeding out the baby vines you don’t want. (Often they will all germinate after a rain so I went out and just plucked out all the seedlings int tjhe area.)

Sweet Peas
(Lathyrus) – These are mostly winter and spring vines, and I just adore sweet peas. I’ve written a whole article about them, but they are best sown in fall for bloom in spring and winter. I’ve tried many types of Lathyrus odoratus as well as its relatives Lathyrus sativus, a small climber with bright blue flowers that’s best in containers or trailing over short edges and walls, and the perennial sweet pea Lathyrus latifolius. Some varieties of sweet peas get as tall as 6 feet, but they play out their season by May so usually we don’t get to have enormous vines like gardeners do with cooler summers.

Hyacinth Bean Vine (Dolichos lablab) – This plant is perennial in anything warmer than zone 9, so is considered an annual here. I see this vine everywhere in Austin. It’s just gorgeous in midsummer when many plants are struggling. This plant is quite drought tolerant and gets to enormous lengths and heights by the end of the summer. Everything about this vine is beautiful. Its deep green foliage never looks ratty or bothered by pests as other vines can be. Both its flowers (beautiful bright purple pea-like flowers) and seed pods are lovely. Last year I watched as a neighbor’s vine completely went to seed, and the maroon-purple pods lingered on the vine for nearly 2 months. You can see them from a block away.

Cup and Saucer Vine (Cobaea scandens) – this vine is another tender perennial that is usually grown as a summer annual here. It grows very quickly from seed, and is best planted either outdoors after frost is over, or indoors a few weeks before last frost. I’m learning the hard way not to grow too many seedlings together, as their tendrils quickly get intertwined. I first saw it growing at the Antique Rose Emporium in Brenham, Texas. It was October, and this vine was covering a beautiful arbor (with a bed surrounded by phlox, dianthus and roses). Maybe it was the romantic atmosphere, but I loved how formal and shapely its flowers were, and how its full leafiness completely covered the arbor. To grow this from seed, most people recommend placing the seed on its side (whereas when it’s flat, the seed often rots) in the soil, and covering it about 1/2 inch. It germinates in about a week.

Mandevilla (Mandevilla x amabilis) – this tropical perennial vine is tender for Austin, so many grow it in pots and bring it indoors during the short winter (just as they do with bougainvillea). It’s my husband’s favorite. It grows more slowly than other vines and the base of the vine gets very woody looking. I have it growing in a beautiful cerulean blue pot which complements the large candy pink flowers. I’ve tried it in both shade and sun and it seems to like a combination of both, whereas most of the other vines above appreciate full sun. At any rate, it’s neither as leafy as other vines but worth it for the flowers which seem to open one day and disappear the next (so much like hibiscus!). These are best gotten as already potted plants, which are common in most local nurseries in the spring.

Other vines I see frequently here are Scarlet Runner Beans and Carolina Jessamine, which is beautiful in spring with its daffodil-yellow flowers and sometimes grown as a groundcover the way ivy is in some places and as an alternative to ivy (be warned, most ivy is not friendly to gardeners here!). I’ve yet to try either of these vines, though.

    thanks for the name of the caterpillars that keeps eating my passion flowers. it only takes a few days for them to eat all the leaves if i forget to look at them. any organic way to keep them off of the plant?

      Hi Jimmy, I don’t really know a way to keep them off. My passionflowers have taken off like crazy since I wrote this and I have to pick them out like weeds! The great thing about having multiple vines, though, is that the caterpillars usually pick one area and there are some others left alone. I prefer to let them go at it because by the late summer my garden is covered in monarchs! And that’s the time when the passionflowers are really blooming and bouncing back from all the munching, too.

    I just. Received cuttings from a Hugh Mandevilla plant. How do I replant this?? In water or potting soil to get roots growing. I love this vine and desperately want this to live.Its Fall now, frost tonight. HELP. Please. Thank you, Kathy

      Sorry, Kathy, I don’t know if I can help with a Mandevilla plant. I no longer grow them, but you’d definitely put it in potting soil not just water. I do know they are tender, especially if cuttings or a young plant. If you are in central or north Texas keep a watch out for frost and bring it in or cover it while it roots.

    Hi. I have been searching for May Pop seeds or plant and came across your website. I live in Hutto,TX , is there anyway you can spare me some seeds or give me a vine or something to start growing them? I have a small garden and have some Asian vegitable seeds that I can give you if you woul like.
    Thanks.

      Hi Julie, I’m sorry to be catching your comment so late after you left it. I got my plant at the Natural Gardener nursery outside of Austin, but they do seem to be quite common in nurseries in this area. My vine turned into several–they come back year after year and spread like crazy, so I’ve never really taken any seeds from it. (I don’t even know what the seeds look like! I should probably investigate.) But I hope you are able to find one. They are so beautiful by the end of the summer, and covered in monarchs.

    Hello! Awesome article – you seem to be very familiar with the vines and I’m hoping you can make a suggestion for me. I’m not sure if I’ll be able to pull it off but I’d like to grow vines on the interior walls of my apartment balcony(about 3 feet deep). I’m in the 78729 zip code so not much different from where you are in central Austin, but I’m hoping for something that will grow well in pots and also can ideally grow in limited light and will survive all seasons. Not sure this is possible but if so please let me know!

    Thanks!

      Hi – hmmm, I’m not well-versed in vines that grow in pots. All of mine are in the ground. Two of the most tenacious are Virginia creeper (grows beautifully up the bricks on our chimney) and trumpet vines–both of which get rather weedy if I don’t control them. So they might be what you are looking for. Virginia creeper dies back in winter (it is perennial but the leaves and some of the vines will die back to the soil, only to return in spring). Trumpet vines need something to cling to–they won’t just stick to the wall. They have a lovely red trumpet flower all summer long that attracts hummingbirds. These sometimes stay green in winter (depends on how cold it gets). Both of these do well in shade–you’ll get fewer flowers on the trumpet vines in shade but they do occasionally flower there. I don’t know of any totally evergreen vines–as in, perennial vines that are green year-round.

    We have a large pergola (10′ high x 12′ x 12′). Last fall we removed an old Crossvine that had been there for a number of years. We planted four “Madison” (?) Star Confederate Jasmine vines and watched them grow taller until the winter weather set in. Due to the freezes in our area we now have nothing but roots that are barely alive. All of the branches and leaves turned brown, fell off and died. Question: If you wanted vines that were: 1. as evergreen as possible 2. as freeze-tolerant as possible 3. with pink, purple or white blooms what would you suggest?

      I’m so sorry to hear that! I love the confederate Jasmine vines. They make such a pretty fence or pergola cover. And for the most part they are evergreen in my garden (I’m in Austin). But this winter was an unusual one here; we had more freezes than normal. Well, we don’t normally have freezes! So mine turned brown for the first time.

      To answer your question, I think the confederate Jasmine is the best option in ever green vines, at least where I live. All the other vines I can think of aren’t evergreen, die back in winter, or don’t have those color flowers. Other than climbing roses, the Jasmine are my most evergreen vines. Your plants might still be alive. It’s been a dry spring, so try and keep them watered and see if they start to bounce back. Good luck!
