This last one is fascinated to a light to moderate degree. Not so with the first three in the preceding post, however. I think it's quite common for regale types, and especially regale album to thicken the stem at the base of the flowerhead where umbel (umbrella) style inflorescence is involved. Most often this thickened area of the stem will take on the appearance of I-beam configuration which gives it tremendous strength. I think it's the plants and mother natures evolved way of dealing with such a heavy load of flowers and to keep it from snapping off during high wind and heavy rain events. In some cases, you'll see the typical umbel configuration transition somewhat into a more raceme vertical form which may or may not develop this I-beam configuration, depending on bud count. The first three look very healthy and the flowerhead will likely grow a couple more inches taller yet. Looks like about 10 days to bloom---post pictures.
