Both indian and pakistani dahlia are available. Pakistani is grown from seed and flower is single or semi-double. Indian one is grown from cuttings and flowers are double and very large. Stacking is required. Indian one needs more care than pakistani one specially in severe winter. you can buy cheap cuttings in october/november or buy small plants early in season. you can save tuber for next month while keeping it in soil. Not grown good from tubers in my experience.
Flowering: December- June

Ranunculus grows from both seeds and corms. Plants grown from seeds have larger flowers than corms so i prefer to buy seed grown seedling from nurseries which is cheap. For growing it from corm check this post of minehttp://www.lahoregardening.com/2009/12/growing-flowering-bulbs-in-warm_04.html Remember not to deep plant the seedling of ranunculus in soil bed. The seedlings grow new shoots from much above the soil level. Also it needs to be protected from march rains.

Growth Ease: Easy
Germination: From corm easy, From seed moderate to difficult
Sun required: Full sun
Famous series: The seed grown is asiaticus bloomingdale. Corm is probably different variety.
