Accepted Scientific Name: Hereroa puttkameriana (Dinter & A.Berger) Dinter & Schwantes
Z. Sukkulentenk. iii. 24 (1927)
H4382 (MG1522.68) It is nice tiny mat-forming plant with curved leaf with pimply spots. Blooms are yellow in early spring.
Origin and Habitat: Namibia through Cape province, south Africa.
Habitat: Hereroa puttkameriana grows mainly in crevices in rocky outcrops and quartz patches mainly on the lower foot slopes of larger inselbergs. It is usually found in exposed positions in full sun or in partial shade along with other local endemics such as: Aloe dichotoma, Anacampseros karasmontana, Avonia papyracea, Ceraria fruticulosa, Conophytum maughanii, Cotyledon orbiculata, Crassula alstonii, Dinteranthus microspermus, Euphorbia gregaria, Lithops olivacea, Othonna protecta, Pelargonium spinosus, Ruschia divaricata, Sarcocaulon crassicaule, and Tylecodon reticulatus.
Description: Hereroa puttkameriana is a nice densely leafy succulent plant forming grey-green tufts of finger-like, more or less erect leaves. Its showy, scented yellow-orange blossoms appear in summer and open at night. It may at certain stages, be confused with Ebracteola derenbergiana which has distinctly shorter inflorescence with pink to purple diurnal flowers.
Habit: It is a tiny, compact shrubby perennial leaf-succulents, branching from the base and forming clumps or mats up to 30 (or more) cm wide.
Leaves: Leaf-pairs 4-8 per shoot. Leaves 6-7 cm long 6-7 mm wide incurved on the lower part, curved outwards near the tip, tapering and obscurely 3-angled, rounded near the tip, pale shiny green, redder near the tip, with dark pimply dots especially on the keel.
Flowers: 1-3 together, daisy-like to 3 cm in diameter, deep yellow to orange, scented and pollinated by moths.
Blooming season: Summer, blooms opening at dusk.

Cultivation and Propagation: Hereroa is a genus that require little maintenance. In cultivation the Hereroa do very well with the spring summer growing period during which they will be watered frequently and heads for winter dormancy. If you provide the Hereroa with the right conditions, they will reward you with their unique shape, and a proliferation of blooms in spring and summer. Being small plants, a representative collection can be grown on a patio table or a shelf in the greenhouse. Inside they grow fine on windowsills, and will even bloom, if they get enough direct sunlight.
Growth Rate: Slow to Moderate.
Soil: It grows best in sandy-gritty soil and requires good drainage as it is prone to root rot. It can grows outdoor in sunny, dry, rock crevices (protection against winter wet is required) It can also be cultivated in alpine house, in poor, drained soil.
Repotting: Make sure to repot during its more active period, starting in spring.
Fertilization: Feed it once during the growing season with a fertilizer specifically formulated for cactus and succulents (poor in nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrives in poor soils and need a limited supplies of fertilizer to avoid the plants developing excess vegetation, which is easily attacked by fungal diseases.
Light: Keep cool and shaded in summer, need full sun or light shade in the other season. Outdoor they prefer full sun, with some shade in the hottest summer months. Plants in pots prefer light afternoon shade in hottest summer days.
Watering: They thrive in dry and desert regions and are able to stand extended periods of drought and require careful watering. Water minimally in summer, only when the plant starts shrivelling, water more abundantly when they are growing in the autumn and spring, but let the soil dry between soaking. If grown in a container, bottom watering by immersing the container is recommended. It must have very dry atmosphere.
Hardiness: It prefer a very bright situation and require a minimum temperature 5°C (But will take a light frost and is hardy down to -7° C for short periods if it is in dry soil). USDA zones 9A – 11.
Uses: Container, rock garden.
Pests and diseases: It is vulnerable to mealybugs and rarely scale.
Plant Uses: Border, container, edging, ground cover, pot plant, rock garden. The plants also attracts bees, butterflies and other insects.
Propagation: Seed in spring or autumn or cuttings. Take the cutting from a grown-up mother plant. Each cutting must contain one or more heads along with a fraction of root and permit to dry out a couple of days, lay it on the soil and insert the stem end partially into the soil. Try to keep the cutting somewhat upright so that the roots are able to grow downward.
