Aloe marlothii (Mountain Aloe)

Mountain Aloe, Flat-flowered Aloe, Spiny Aloe


Adding a majestic presence to the garden, Aloe marlothii (Mountain Aloe) is a large evergreen succulent forming a dense rosette of fleshy, grayish green leaves, up to 5 ft. long (150 cm), with a broad base tapering to a sharp point. They are covered with reddish-brown spines along the edges and randomly on their upper and lower surfaces. The old leaves remain after they have dried, forming a 'petticoat' on the stem. Single-stemmed, Mountain Aloe produces a spreading, branched panicle with up to 30 racemes borne more or less horizontally. The tubular flowers vary from orange-red to yellow or bright red. Robust and striking, this Aloe makes a beautiful display in sunny borders or decorative containers and is great for attracting nectar-feeding birds.

  • Grows up to 8-10 ft. tall (240-300 cm) and 4-6 ft. wide (120-180 cm).
  • Easily grown in well-drained soils in full sun. Water once a week for the first month following planting and reduce watering thereafter. Well-established plants can survive for several months without water.
  • Great for beds and borders, rock gardens, succulent gardens or Mediterranean gardens. Ideal as an accent plant in sunny borders or in decorative containers.
  • Deer resistant. The flowers produce nectar and are attractive to birds and bees
  • Virtually disease free. Watch for scale insects and mealybugs.
  • Aloe marlothii can be grown from seed or can be propagated by offsets.
  • Native to South Africa
