End of the Season Containers

It’s been over 3 months since I posted the “Before” Container Shots. We’re now into October, and luckily the weather has been mild, with a few chilly nights. All in all, the containers depicted in the early summer post are looking as good if not better.  My goal each year is to come up with combos that are easy care and will look fabulous until frost.  Here are this year’s end of the season shots.zenbowl_detailazen_bowlt_9302017oct72Succulents rule! The Aeonium noticeably is more green than bronzy, and  this space where the 36″ Zen Bowl is located is getting more and more shade…perhaps now only getting 3-4 hours of afternoon sun…it’s getting limited for succulents. I think we’ll have to reconsider what type of plants to use here next year.aaeoniumpot_9302017_72The Aeonium ‘Cyclops’ in the drum pot, with Sedeveria ‘Harry Butterfield’ and String of Pearls spilling over the sides, is still looking pretty awesome. I will be sad when we have to dismantle this container.cylinderpot2017The Cylinder Pot in front of the garage is pretty much doing a repeat performance of last year. The big Kalanchoe beharensis started to overwhelm his neighbors, and was trimmed back several times.white_pots17_72The larger white pot with Cuphea ‘David Verity’, Digiplexis ‘Illumination’ and Ruellia b. ‘Purple Showers’ needed watering attention, but is still blooming away. Not missing a step,  the smaller pot continues to look good with Heuchera ‘Cherry Cola’, Phormium and Euphorbia ‘Diamond Frost’.xgreekurnThe Grecian Urn on the pedestal was one of the shade ensembles, with Begonia ‘Art Hodes’, Cyperus ‘Starburst‘, Oxalis, and Callisia congesta variegata, which needed to be cut back more than once. I know, I know, I put way too many ingredients in this pot.silverfernpot17_72Here’s another shade planter, mixing hardy and tender plants. Maidenhair Fern, Black Mondo Grass and hardy Begonia grandis, are paired with tender Sansevieria ‘Moonshine’ and Dichondra ‘Silver Falls’. This planter was in dappled shade all day, and notice how well the Dichondra grew!
papyrus (1 of 1)Papyrus + Papyrus  + Callisia = … To begin with, I selected too small a pot in June, so what did I do?  In mid summer, I lifted the plants that had filled the pot and moved them into a much bigger container. When the Ornamental Oregano had done her thing, then the Callisia was very happy to take over the pot.ironurn17 (1 of 1)One of the iron urns is getting more shade than in previous years… probably just 4 hours of good sun, and then it’s in dappled light. Here is what it looks like now… the Beschorneria and Golden Ivy seem happy still.whitebegonia_72Someone bought the head pot…so I can’t show how it fared, but instead here is another shady planter. Never took the “before” picture, but I thought this green trough was successful. The white form of Begonia boliviensis seemed happier this year than in the past, and is paired with trailing Pilea glauca, Pilea microphylla variegata, Ornamental Oregano, and  Blue Rabbit’s Foot Fern, which is now pretty much hidden.brownterrabowl17 (1 of 1)Last but not least, the brown terra cotta bowl wants to show off even more now that it is autumn. Assorted succulent foliage looked great all summer. Now, in October, the  Euphorbia tirucalli (Sticks on Fire) is beginning to deepen in color and Senecio ‘Blazing Glory’, bursting forth with orange red blossoms, is ending the season with a bang.

What easy care combinations worked best for you this summer? Have you been using succulents in your container plantings?

Generous Fall Asters

Symphyotrichum (Aster) ‘Vasterival’

Some might consider the term “generous” a euphemism for invasive…but I have my own take on certain vigorous spreaders and self sowers. I say, sometimes a plant with ground covering capabilities is a good thing…it won’t be long before you have a nice swath of color plus the plant’s vigor keeps weeds at bay. Here are 5 Asters that command attention and are easy peasy.

( A little botany note: The taxonomists have reclassified Aster  into several distinct genera in recent years. For example, the genus Aster encompasses species that are specific to Eastern Asia, while the term Symphyotricum includes Asters native to N. America and parts of Europe.)

One plant that really draws comments in our September garden is  Symphyotrichum x ‘Vasterival’, a hybrid of unknown origins. 3/4″ daisies in a  sweet shade of pink/lavender are born in loose sprays on tall dark tinted stems. You could  pinch plants back in early July to control height, or let them do  their thing, and have stems that can reach 5′. ‘Vasterival’ is a perfect plant for that “garden gone wild” look. Plants spread by stoloniferous roots.

Symphyotrichum x ‘Mary’s White’

Another Symphyotrichum selection that has proven quite vigorous is ‘Mary’s White’, which was selected by British nurserywoman Beth Chatto and named for her daughter. 1″ white daisies are carried on sturdy 3-4′ stems during September into early October.

Aster ageratoides ‘Ezo Muraskai’

The Asian Aster ageratoides ‘Ezo Murasaki’ is the boss in a bed where we once had  plants with meek dispositions. We  let ‘Ezo Murasaki’ fulfill its ground covering mission, and moved its less vigorous neighbors. Yellow centered violet 1″ daisies are born in  clusters on 18″ stems from late September into November.

aster_laevis_bluebird500

Symphyotrichum laeve ‘Bluebird’

Some Asters self sow nicely.  Symphyotrichum laeve ‘Bluebird’, commonly called Smooth Aster, is one we allow to seed about and establish informally in beds where a little autumn color will be welcomed. Quarter sized flowers have lavender blue petals with yellow centers open up in stages in loose sprays. ‘Bluebird’ grows 3-4′ tall, but bows gracefully around its neighbors.

aster_ericoides_kolwitz500 (1 of 1)

Symphyotrichum ericoides with Elscholtzia and Kolwitzia

Another promiscuous seeder is the Calico Aster Symphyotrichum ericoides. Height can vary, but most often  plants are in the 18-24″ range. Don’t you think this Aster picked the best spot to establish itself, here between the Chinese Mint Shrub, Elscholtzia stantonii alba, on the left, and the golden leaved Kolwitzia on the right?

 

Tips for Fall Containers

Black Mondo Grass with hardy succulents

Are your summer planters in need of a fall makeover?  Are you thinking you would rather invest in perennials than toss away non hardy plants at season’s end? There are many fall-flavored hardy plants which will provide you with texture, form and long lasting colorful foliage. Plants to consider include Ornamental Grasses, Ophiopogon, Hardy Succulents, Heuchera, Euphorbias, Ivies, Dwarf Evergreens, to name a few.

Here’s a few tips.

1. To achieve a fuller affect, use more plants than you would in the spring or summer.  We don’t want to think about this now, but the days have been getting shorter, nights cooler, and plant growth is slowing down or ceasing.

2. Select plants that have a variety of tones that will contrast and set off each other, (think amber Heuchera and black Ophiopogon).

3. Remember a pot of mums looks fresh for 3-4 weeks at most, then the show is over. Showy foliage will carry on and on.

4. Note that the fall foliage on evergreen Sempervivum (hens and chicks), Sedum ‘Angelina’, and Sedum album cultivars change and develop more dramatic color once the temperatures stay cool.

5. If you must have flower power, consider long and late blooming Salvia, Cuphea, or fall pansies.

6. When a night time temperature drop is forecasted, have light blankets, large pots or even an empty trash barrel handy to cover your container and protect the plantings from frost.

7. As November passes, he time will come to  disassemble your planter. Tuck your hardy plants in a nursery bed or empty space in your vegetable garden plot to hold them over until next spring.
