Succulents grown for distinctive rosette forms topping spikes that range in height. There is also a wide variety of foliage colors available including vibrant yellow-green shades, muted gray-greens, deep blackish purples and some are green in center with red edges. Aeonium are related to and at times mistaken for echeverias. Aeonium do well in partial and full sun but can suffer from foliage burn under harshest condition. The plants are only moderately drought and frost tolerant. New plants can be easily propagated from cuttings.
These annuals are sometimes called Cape Marigold, Cape Daisy and Rain Daisy. With mild winters, African Daisies can perform as perennials. The spring flowers feature daisy-like blooms in shades from white to purple. It is important to plant where sun is ample to maximize blooming. There are related hybrids with orange and yellow flowers and the plants are closely related to Gazania. It helps to dead-head spent blooms for more flowering. African Daisies are readily propagated from seeds.
Spikes of flowers in mid-spring offer dramatic forms that resemble fireworks. The foliage retains a glossy appearance with little upkeep and water throughout the season. In some areas, blue agapanthus are so heavily used along highways that home gardeners eschew them as too common. In these cases, dwarf plants and those with white, dark purple or pink flowers bring an unexpected look. Agapanthus do well in partial shade to full sun in all but the hottest summer gardens.
This succulent shrub features a tight rosette of fleshy leaves. Many agave varieties are available with differences in leaf color some of which can be variegated. There are also significant size differences between varieties. Agaves do well in very low water situations. Agaves feature stunning leaf arrangements and dramatic forms that can lend a modern minimalist feel to a gardenscape.
Tiny clusters of flowers top this low growing annual. Alyssum grow readily and come back through self-sowing. They are effective as underplantings for rose gardens and mixed in with bulbs to obscure dried foliage after tulips and or other bulbs are spent. Alyssum can also be attractively used in rock gardens, between pavers and trailing in pots. If growth gets out of hand they are easily pulled. The flowers have a sweet fragrance. White and purple are the most common colors. Yellow, pink and cream colors can also be found and are less typical.
This clumping grass-like ground cover is also known as “sea drift”. It tolerates poor soil including coastal areas. Armeria Maritima does well as an underplanding for shrubs, in rock gardens and as a border. Until blooms appear it looks very much like grass leading some to inadvertently weed it out. The spring blooms appear as puffs on short stalks. The entire plant reaches 7-8 inches in height, half of this before blooming.
This round cactus can provide striking architectural impact in a rock garden and landscapes seeking a modern, streamlined look. In addition to the round shape, barrel cactus are noted for pronounced white or yellow spines. Flowers take several years to appear in circle pattern at the top. Obvious care needs to be taken in locating barrel cactus plantings to avoid neighboring plants that may invade given the difficulty in working amongst the sharp spines.
This perennial shrub is also referred to as an “African Lily”. The plant features grassy sword-like evergreen foliage and attractive flowers with distinct spots. They are vigorous plants but do take some time to become established for flowering. Care needs to be taken in site selection as the plants are very unattractive if invaded by trailing ground covers and they are difficult to weed.
