Another example of using texture and line in the garden
This relatively simple planting composition is another example of how to use contrasting textures of plant foliage to achieve an effect. The course teeth of the Aloe foliage, which are further heightened in impact by having a contrasting color to the leaf which catches the light, pop in relationship to the multi-hued silvers, lavenders and pinks of the adjoining Graptoveria 'Fred Ives' succulent next to it. The contrast between sharp and soft attracts the eye, and the further contrast between the rigidly vertical bloom stalk of the Aloe x delaetii against the leaning flower stems of the Graptoveria is another contrast. All of this is further heightened in effect because they are playing off a neutral blank wall backdrop.
None of these planting compositions are so pensively thought out in advance, but more intuitive from growing and observing the individual plants, and recognizing their intrinsic design qualities and how to exploit them. The secondary aspects of the complementary flower colors and the bit of color echoes between them is probably even more intuitive and less determined intentionally in advance. I may find that the color combinations don't always work 100% of the time, but may elect to leave them be if it is just a fleeting conflict. When flowers last over several seasons, it is simply easier to work with combinations as one lays them out in the garden.
