Aloe thraskii
Aloe thraskii is a majestic, usually single-stemmed arborescent aloes that will in time bear a massive rosette of beautifully recurved leaves. It is among the tallest aloe species usually 2 m high but sometimes up to 4 m and produces showy yellow candle-like spikes of flowers.
Leaves: Up to 160 cm long and 22 cm wide, broadly lanceolate, channelled, curving strongly downwards, pale olive-green, dull green to greyish-green or glaucous, sometimes with a few spines on both the upper and lower surfaces. Margins armed with reddish prickles maturing from initial white teeth on young leaves recurved back to the trunk about 2 mm long, 10-20mm apart.
Flowers: bright yellow or Yellow-orange.
Blooming season: Mid winter.

It is easy to cultivate
Growth rate: It is a fast grower and appreciates a lot of water in warmer weather.
Exposure: It will do its best in full sun and become stressed with inadequate light. Will handle very harsh sunlight.
Hardiness: Aloe thraskii is a hardy aloe but not completely frost resistant. It will survive light frost but the flowers will not, but for safe cultivation it is best to avoid freezing temperatures. USDA Zone 9.
