About Skyblue Clustervine
Skyblue Clustervine (Jacquemontia pentanthos) is a Florida-native evergreen vine in the morning glory family, bearing small sky-blue flowers primarily fall through spring — providing rare winter color in NE Florida gardens. It twines easily on fences and trellises in coastal and scrub settings and is a valuable nectar source for native bees and sphinx moths. Starting at $9.95.

Care essentials
Light
Plant in full sun for best flowering; this native vine performs poorly and blooms sparsely in part shade. In NE Florida, a south- or west-facing fence or trellis in an open, sunny spot is ideal.
Water
Extremely drought-tolerant once established in NE Florida's sandy soils; water during establishment (first season) then rely on rainfall. Avoid overwatering — soggy roots cause decline.
Soil & Fertilizer
Thrives in lean, sandy, well-drained soils typical of NE Florida coastal areas; no fertilizer needed and excess fertilizer promotes foliage over bloom. Amend clay spots with coarse sand to ensure drainage.
