You caught my slip up there. What I meant to say was oranges require heat for the fruit to ripen. they flower all at once in the the spring and need heat for many months to produce an edible fruit. Where as lemons flower all through the year and you can harvest good fruit in January. I mean it, youtube that one. Some guy in canada grows meyer lemons outdoors year round and can pluck fruit in winter.Seeds definitely require heat to germinate
Key limes are vigorous with small leaves, or at least mine were. They keep them in stock pretty often at wegmans if you have those down there. They were the only citrus I'd consider for bonsai outside of bitter orange, which has bigger leaves
