Sunny yellow petunias and a dark blue lobelia.

How about a lovely sedum, one with a touch of red/orange in it to complement the blue ? It would be especially nice to have it spill over the edge, soften it a bit. With the orange one, I'd do the opposite - fill it with succulents of bluish-gray hue.

I would swap the two containers, put the Agave in the orange container and the color combo in the blue one.

I'd try Mexican Feather Grass - stipa tenuissima perhaps, or Japanese Forest Grass -- Hakonechloa aureola.

I'd do something bright - like a campfire crassula (http://www.anniesannuals.com/plt_lst/lists/search/lst.srch.asp?prodid=2928) paired with a trailing lime green sedum of some kind (say ogon sedum). I think the vibrant greens and oranges would offset the turquoise nicely!

Something in lime green....in fact several plants with lime green foliage....also...a white flowering pllant.....with lime green flowing over the sides.

What fun suggestions! Keep 'em coming.

Amaryllis + hydrangea!

Stick plant (uphorbia tirucalli)!

Lantana! The warm color and delicate mini-bouquets of red and orange will be a great counterbalance to the straight lines and aqua blue color.

Ooh, I like the lantana idea.

I like it, too. I never would have thought of that.

A colorful gerbera daisy would look great against the blue!

I love this pot, especially the color. I wish I could remember the name of them, but there is a plant that has succulent style leaves, but produces yellow flowers with pink middles. I have them in my front porch pots (which are the same color as this pot). What I love about them is that they are a bit spiky, but also soft with the delicate flowers. The yellow is also a perfect contrast to the blue. Wish I could think of the name!

OK, the name is Portulaca Grandiflora, or moss rose. Finally remembered it! :)

I'd plant it with a clump of deep burgundy Aechmea 'Merlot,' an upright, vase shaped bromeliad that stands about 14" tall.

It would be a stunning color contrast and the simple architecture of the bromeliad vases would echo the ribs of the pot.

Cool!!

I'd love to see an aloe vera in that beautiful pot!

My first comment (which seems to have disappeared) said black mondo grass (Ophiopogon planiscapus) because the color contrast would be striking. Then I thought of Agave Americana ‘Medio Picta Alba’ because the blue of the leaves combined with the pot color would make the white stripe on the leaves POP! Then today I saw my Yucca 'bright star' and realized how perfect the blue and yellow leaves would look with the color of the pot and the shape and spikyness would go with the pot texture so well.

Another spike lover like myself, I see. Love all these ideas.

An apricot cymbidium. Or a bright orange cattleya. Or mysterious zygopetalum.

Anything that would cover up that aqua color.

I like the color and the almost mechanical design of the pot. It looks small in the photo, but at 16 inches across, it's large enough to plant with things other than succulents.

I think a clump of Cyclamens would look great, buy my focus is on Arizona native plants, so here are my ideas for using them.

1. Plumbago scandens (Plumbago) for a cascade of deep green leaves that turn burgundy in winter. It has lovely white flowers too. It would do best in part shade.

2. Mimulus cardinalis (Scarlet monkeyflower) for its soft green leaves and orange flowers that complement the blue pot. This would need to be in shade and kept on the moist side.

3. For a sunnier location, I'd make a mini trellis for growing Maurandya antirrhyniflora (Snapdragon vine). It's a very delicate small vine with arrowhead shaped leaves and red or purple flowers. I'd use the former in this pot. Around the vine, I'd plant Dyssodia pentachaeta (Golden dyssodia). It's evergreen fine texture foliage would spill over the edge and the yellow flowers would give it a bright perky look.

I'd make the trellis out of a material that picks up the industrial design of the pot. In this case, a grouping of three uprights made from 1.5 inch wide springs that I got at a junkyard. I'd vary the heights - one at 24", one at 20" and one at 16" and cluster them towards the back of the pot. I'd let the Snapdragon vine grow up this and plant the Golden dyssodia in the foreground. I'd "gravel" the soil surface with tumbled recycled glass shards.

Pardon the typos in my previous post....

Turns out I can't stop thinking about this container! I go about my gardening day and I seem to be looking at every plant with an eye to how it would look in the turquoise container. Today has me thinking that Graptopetalum paraguayense would be a stunner!
