How much time needed to start tuberous begonias indoors?

Before planting out, that is. I ordered tuberous begonias online yesterday. I usually start them indoors, but never noticed how long it really takes before they seriously get going. I think in the past I didnt start them early enough, just did them when I did the dahlias. In my order confirmation the seller (Easy to Grow Bulbs) says they can send them at whatever time I want them, now or wait. This got me thinking

Here, planting out doesnt get done until the last week of May. If I want a really impressive, lush display, ideally, when should I start these? How much time should I allow for indoor growth? 1 month? 2 months?

Another issue: Ive never had anyone hold a shipment. I ordered early because I didnt want them to run out. But am I more likely to get the "leftovers," the smaller bulbs, by NOT taking them right away?

RE: How much time needed to start tuberous begonias indoors?

My tuberous begonias tell me when they are ready to grow. I will put them where I can watch them, in a wire basket with room to keep them apart. As I notice the buds develop I plant them, buds facing up with little or no soil covering the buds. Keeping the soil damp, not saturated, inside in good light. I have never paid attention to the time spent inside before putting out in a protected place. Most of mine are planted now. If I wanted to delay them growing, I would keep them cold. Al
