Awesome Annuals

Senecio_confususMexican Flame Vine
Senecio confusus
Last fall I visited the spectacular, wildly innovative Chanticleer Garden in Pennsylvania and saw unusual plant after unusual plant that I had never seen in real life before, but knew that I could get at …. the Friends School Plant Sale! This Mexican Flame Vine, with its daisy-like flowers but lush and tropical look was one that went instantly onto my shopping list. It needs full sun and will grow to 8 feet.
Verbena_bonariensisBrazilian Verbena
Verbena bonariensis
This unique 4′ purple flower can be used in so many different ways. Here it is interplanted with annual butterfly flower (see below) to give the human eye a color shock and signal to the butterfly eye “Come and get me!” It can go in the back of a cottage or classic border to give height that doesn’t need staking. Or, since Brazilian Verbena has such skinny stems and small leaves that you can see right through it, gardeners plant it in front of other plants despite its height. It’s a natural planted in masses with grasses in the New Wave style of Piet Oudolf.
Dixter_verbena
Brazilian Verbena, continuedHere you can see how it is planted as an exclamation point in the Exotic Garden at the late Christopher Lloyd’s Great Dixter. If you want a bushier plant, just pinch it back. And it is great in bouquets, easy to stick in last. This is a flower worth learning the Latin name and pronunciation of because it is actually the one most commonly used. Pronounced by those who seem to know these things, it’s: Ver-BEE-nuh buh-nar-ee-EN-sis. That’s botanical pseudo-Latin for the Brazilian city of Buenos Aires, where the seeds first came from.
Tithonia_TorchMexican Sunflower
Tithonia ‘Torch’
Two years ago I bought six tiny fuzzy little plants at the sale. Refusing to believe that each would get to be over 6 feet tall (”This is Minnesota! They won’t have time to get that big!”) I planted them a couple of feet apart in my small front garden. They looked ridiculous. Quite soon, though, it was I who looked ridiculous as each one grew not only that tall but also that wide. I tried to hack them back to some reasonable size, but the monstrous plants just laughed. In the end, I ripped out all but two, but these two were truly magnificent, throwing out big, orange, velvety daisies in every direction and attracting all the butterflies and hummingbirds in the neighborhood. Last year, I doubled the size of my front garden….
Firecracker VineFirecracker Vine
Mina Lobata
This is one happy, vigorous flowering vine! The colors are even brighter than in the photo and the slightly purple, lobed leaves and twisty tendrils are stunning all on their own. Be sure to give this vine a very strong support!
Asclepias curassavicaButterfly Flower, Silky Red
Asclepias curassavica ‘Silky Red’
It’s hard to say enough nice things about this annual butterfly weed. I’ve grown it for six years and never tire of the way it just blooms its heart out all summer and even after some light frosts. The plants are tall and linear, unlike the perennial butterfly weed, so you would think I’d plant it in the back of the border, but instead I put it near the front so that I can deadhead it easily. You don’t have to — the seed pods are lovely — but you will get more and more blooms if you do. Butterfly Flower looks equally at home in both tropical and more naturalistic gardens.
Millet JesterMillet, Jester
Pennisetum ‘Jester’
I had no idea how much I’d grow to like this dramatic and architectural plant — this year I will definitely buy more than just one! It is not quite as black as it looks in my photo, especially earlier in the summer when the new foliage is charteuse and reddish and purple, and I wish you could see how beautiful those seed heads are close up. They look amazing in bouquets and also dry well.
Capuccino Sedge Sedge, Cappuccino
Carex ‘Cappuccino’
See the plant that looks rather like dead grass? Now, try adjusting your vision: NOT dead at all, but a gorgeous copper-brown sedge that works well with hot colors and can be an unusual addition to many imaginative container color combinations, for instance, copper and coral and burgundy. We also have another sedge called ‘Toffee Twist’ — sound yummy yet?
Balloon CottonBalloon Cotton
Asclepias physocarpus ‘Oscar’
Another oddity. Not knowing what wonderfully strange seedpods this butterfly-flower-relative would develop, I pulled it out of my orange flowerbed when I saw its white and green flowers. Now, I would happily grow it to use the green pods in bouquets, like they do at the Farmer’s Market.
Pepper, Black PearlPepper, Black Pearl
Capsicum annuum ‘Black Pearl’
Of all the plants I saw on all the garden tours last summer, it was this almost perfectly black-leaved ornamental pepper that caused the most talk. “Can I eat it?” Yes, if you don’t mind that it tastes terrible. “What could I plant it with?” Try red nasturtiums. Or coleus. Or falling stars (Crocosmia.) And, over and over, the question “Where can I buy it?” Well, now you know.

Loading up the wagon

Image and video hosting by TinyPic

The equipment I use to shop at the sale probably seems a teeny bit excessive, but it has worked for me for years and may at least amuse the more spontaneous shoppers!

I take two wagons, loaded up with stackable plastic bins, and some more or less willing family member to be what he calls my “beast of burden.” My wagons are now well labeled after an experience of trying to help a woman at the sale find her lost plants.

I always take a basket with handles, so that I can shop up and down a long aisle, parking my wagons with my “beast” at one end or in an uncrowded spot. My most ridiculous piece of “equipment,” which I refuse to photograph for you, is an ancient red nylon windbreaker with a huge kangaroo pocket in the front for keeping the catalog, price list, shopping list, pen and cellphone handy.

What I like about my system, besides the fact that it enables me to buy ten times more plants than using a grocery cart, is that after we go through the check-out line, it is so easy to load all the containers into the car and then unload them at home. The plants stay in their containers (with the lids off!) on the porch or, some years, in the living room, until I can plant them.

By the way, I buy at the sale both Thursday during the volunteer presale and Sunday during the half-price sale, so I get to use my equipment system twice.

Some of the New Perennials for 2007

Nancy and I are going to be posting photos of new items we will have at the 2007 sale because, as she says, “I love the idea that eventually, someone could browse through many of the plants (and SEE them!) on the website as well as the catalog.

Try a Black-eyed Susan Vine (Thunbergia)!

Image and video hosting by TinyPic

Looking for a cheerful, easy annual vine that tolerates part shade and although a quick grower will not overwhelm a container, hanging basket or trellis? One of the Black-eyed Susan vines should be on your list for this summer.

Thunbergia ‘African Sunset’ resembles the regular golden or orange Black-eyed Susan Vines in the above photo except that as the numerous 1” flowers bloom and age you get an amazing number of different colors: brick-red, rose, mauve, coral, apricot, salmon, and cream to name a few! This twining or trailing vine, nicknamed “Blushing Susie” for obvious reasons, is native to western Kenya and grows rapidly in sun or part sun, blooming from early summer to fall.

Thunbergia ‘Sunny Lemon Star’ is a soft, clear yellow that will fit into a pastel color scheme more easily than the usual golden-yellow. It will cascade from a hanging basket or scramble 6-8 feet up a small trellis. Plant more than one for a fuller effect.

Thunbergia grandiflora ‘Blue Sky’ or Blue Sky Vine is a much larger and more exotic-looking annual vine which can grow 15-20 feet with 3” lavender-blue flowers. Full sun to part shade. Keep it consistently moist.

Falling Stars (Crocosmia) Shine in the Garden

Four crocosmia varieties“What’s THIS?” visitors to my garden often exclaim, standing in front of a plant with tall, sword-like leaves like an Iris but with arching sprays of delicate, funnel-shaped, hot-colored blooms. This is Crocosmia (kro-KOS-me-ah) and one of my favorite flowers.

I first saw it in photos of gardens in England and had to have it. I am a sucker for just about any red or orange flower, and this one’s many, small vibrant blossoms had a simple, almost wildflower look, quite unlike the bold flowers of my tulips, poppies, daylilies, Dahlias, Mexican sunflowers (Tithonia,) and Cannas.

I learned that Crocosmia is attractive to hummingbirds and quite bug-, disease-, rabbit-, and deer-resistant. Its name comes from the Greek krokos meaning saffron and osme meaning smell, because the dried leaves are supposed to smell like saffron. Crocosmia is native to several countries in Africa, first hybridized in France in 1879, and quickly obsessed the English who created hundreds of varieties before World War II (three-quarters of them since lost to cultivation–there are now “only” 270+ at the National Collection of Crocosmia in England.)

Their dramatic foliage and cheerful blooms of gold, peach, tangerine, burnt orange, or scarlet arranged in a herringbone pattern up the stem look great growing out of a patch of nasturtiums or Lady’s Mantle (Alchemilla) or perennial cranesbill (Geranium) in the late summer and fall garden when many other flowers are looking tired. And they make excellent and long-lasting cut flowers–florists love them, often calling them by their former name, Montbretia.

national_collection.jpg
So, what’s the catch? Here in Minnesota, only one cultivar, ‘Lucifer,’ is usually hardy, although more and more I see catalogs listing the Crocosmia that used to be zone 6 as zone 5 or even 4! For several winters, I have dug and stored my Crocosmia bulbs (actually corms) like you do with a Gladiolus, Dahlia, or Canna, but last winter I left all ten varieties in the ground covered with an extra-thick layer of mulch. So we’ll see what happens!

Cultivation

  • Full or dappled sun
  • Rich, loose, very well-drained soil. Try surrounding each corm with sharp sand. They also do very well in good potting soil in containers. Some say that they do not like hot, dry sites. Mulch well.
  • Plant corms 4-6 inches deep, 2-4 inches apart. Each corm will send up a few leaves and usually just one flower stalk, so plant at least eight together. You could also pot them up indoors in April in order to give them a head start. Watch out for spider mites, as you would with many indoor plants.
  • Avoid high nitrogen fertilizers; keep well watered.
  • Crocosmia blooms from July until frost, each variety on a slightly different schedule.

In late fall, you can cut off the leaves, dig up the corms, dry them for a few days, and store them in paper bags in a dark, very cool place (some experts say 35-45 degrees, while others say 55-60 degrees) or even a refrigerator–I use a small, dorm-size refrigerator just for overwintering Crocosmia corms and Dahlia tubers. Some say to store the corms in sand or vermiculite rather than just loose in a bag, in order to keep them from drying out. The smaller the corm, the more this is worth doing.

Or, you can try leaving the foliage on and covering the plant with a very thick layer of oak leaves, straw, or wood chips (say, at least 12 inches) when the ground starts to freeze. Being wet during the winter will rot the corms. ‘Lucifer’ is listed as zone 5, and it is thought that other cultivars may be hardier than originally supposed. It is well worth a try, because Crocosmia blooms better once established in a good-sized clump.

Varieties we will have at the 2007 sale

The Friends School Plant Sale lists Crocosmia under the common name Falling Stars in the annual section of the catalog, given the fact that they are classified as Zone 5 and 6. We sell the corms bareroot in our Lily Shop area. This year we will have:

  • Carmine Brilliant
  • Emberglow
  • Emily McKenzie
  • John Boots
  • Meteore
  • Lucifer

How Did It Grow for You?

Tell us about your successes and failures with plants you purchased at our sale over the years.

We would especially like to hear about unusual plants. Did you try the Marsh Helleborine, Epipactus palustrus, the Japanese Maple varieties we carried in 2006, or another plant that was new to you?

Did it survive the winter? Thrive and spread, or dwindle and die? Did it misbehave (become weedy and crowd out its neighbors)? Did we provide enough information its requirements?

We’d also like photographs of plants growing in our area.

Please let us know! Write to us at info@friendsschoolplantsale.com.
