Please help ID this plant. Seeds were flat, dark and teardrop shaped. About the size of watermelon seeds. Leaves are heart-shaped and hairy. Stems are very thin like clover and also have the fuzzy little plant hairs on them. Plant is 2-4 months old, grown in daughter\'s dorm room. She got seeds secondhand from a friend, who said they were bamboo gotten from the university\'s college of agriculture. That doesn\'t soubd right. We haven\'t seen any flower buds yet. Geranium? Hollyhock? Violet?
