Solanaceae
Cup of Gold Vine: Fast Growing
Solandra maxima
Requires full sun (at least 6 hours of direct light) to bloom well; in very hot inland areas, it appreciates some shade. It needs moderate watering, rich, well-drained soil, and a very sturdy support structure. It does not tolerate frost, suffering damage below 32°F (0°C). It blooms on new wood, so pruning after flowering keeps it manageable and stimulates more blooms.

What Diseases Commonly Affect Cup of Gold Vine?
TLDR: Cup of Gold Vine is susceptible to 3 known diseases. Monitor regularly for early detection.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Scale Insects
Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
Cold Damage
Cold damage, also known as frost injury, occurs when plants are exposed to freezing or near-freezing temperatures. This environmental stress can cause cellular damage as ice crystals form within plant tissues, rupturing cells and disrupting normal plant functions. Chilling injury can also occur in sensitive species at temperatures between 32-55°F (0-10°C), even without actual freezing.
