Sun Sugar is probably one of the sweetest cherry tomato variety.  The golden bite size fruits are sugary, slightly tangy, great for snacking or mixed in with salads.  The skin is thin but they are surprisingly very crack tolerant.  The plants grow vigorously and can easily reach 5-6 feet tall producing lots of tomatoes.  They love being in full sun and heat does not seem to affect them much.  With some pruning, they can be excellent as potted plants.
