The plants' first upright leaves emerge in spring. After two or three leaves have formed, the nominal form produces a small, solitary white flower, 13 mm across, which is borne on a short stalk in summer, and positioned near the top of the leaves. The giant, lowland form produces 1–5 flowers on a long inflorescence up to 25 cm long. Flowers are present from November to February and fruits are present in January–March.
''D. arcturi'' is a summer grower, and after flowering its leaves gradually reduce in size to form an elongated, horn-shaped hibernaculum. In this form it passes the cold, harsh alpine winters. The hibernaculum is normally buried near the surface of the soil or moss and is usually covered with snow for several months during winter.

The leaves of ''D. arcturi'' are linear, 1–5 cm long, undivided, and range in colour from pale green to muddy brown, to maroon if subjected to full sunlight. Like all other species of ''Drosera'', ''D. arcturi'' catches insects using sticky, glandular hairs on its leaves. In ''D. arcturi'', these glandular hairs are red. Young leaves begin at the center of the plant and are folded along their center. Once the young leaf reaches full maturity it unfolds like a book.
The plants' first upright leaves emerge in spring. After two or three leaves have formed, the nominal form produces a small, solitary white flower, 13 mm across, which is borne on a short stalk in summer, and positioned near the top of the leaves. The giant, lowland form produces 1–5 flowers on a long inflorescence up to 25 cm long. Flowers are present from November to February and fruits are present in January–March.
