Because these plants usually have small root systems, (they don’t need to constantly gulp down as much water as other types of plants) they are ideal to use in small spaces like cracks in walls, between stepping stones, for green roofs in sunny climates, in vertical gardens or container gardens. They can also create impressive effects when tumbling down walls or carpeting hillsides.
Because the shapes are so varied – strings of colorful pearls, big felt leaves (Kalanchoe beharensis) mats of fine foliage (Sedum rupestre ‘Angelina’), or a crisscross of pencil-like branches (Euphorbia tirucalli), they are ideal to use for textural effects or even eye-catching focal points in the garden.
Some succulents are more colorful than the average garden flower. The Echevaria family offers a rainbow of pink, purple and blue leaves on the “Afterglow’ variety, Aeonium comes in dark mahogany shades that contrast like black with other foliage, and many of the artichoke shaped Sempervivum plants are striped, spattered or netted with colors. You can find foliage that stays red, orange, yellow, green, bluish, purple, black or white – fuzzy, shiny, toothed or textured – all the time; no need to wait for blooms.Some offer exciting flower colors. Blooms can be found in almost any color, some large and exotic looking, some small but smothering the plants in huge numbers. Various plants known collectively as “Ice Plant” are well-known in warm climates for blanketing hillsides with brilliant hues in early spring. The Century Plant (Agave) is impressive sending up two-story-high flower stems that branch into predominantly green flowers that look like trees and can be seen from long distances away. Brilliant red, yellow, orange and coral flowers bedeck many aloes while some cactus plants (all succulents) can produce flowers that dwarf the parent plant. Use succulents to add color to hillsides, gardens (on their own or mixed in with other plants), or in container gardens. Their colors and interesting sculptural forms can create interest when nothing else is in flower. Most succulents can take periods of drought, sun and shade. Some can handle frost – even hard frosts. Double check the plants you buy to make sure they will thrive in your climate and where you want to grow them in your garden. There are so many different kinds of succulents; you are bound to find a number of them that are perfect for your landscape.
