MrsBinWY On May 1, 2023 Bloomed
Two of the three plants I kept for myself opened their first blossoms in May 2023. Each plant sent up one flowering stem. The blossoms opened over a long season, and the seeds began maturing in August 2023. Only two or three seed pods still maturing as of September 19, 2023.
MrsBinWY On May 22, 2020 Potted up
20 - big, fleshy roots; had to swish them around in a pot of water for
a very long time to get them apart
MrsBinWY On December 22, 2019 Seeds germinated
1 of the "floated" seeds that sank showing a radical (added it to the milk jug with the other seeds; moved the milk jug to the bathroom floor to the side of the heater vent); another sinker showing a radical on 12-23-19 (will leave this one a while to see if it can progress under water; dropped the water level such that the seeds are barely covered); the other 2 sinkers were showing their radicals on 12-26-19. (All 4 sinkers germinated in water.) Also on 12-26-19, I can see one of the seeds sown in the milk jug (not the "sinker" that germinated first) has a nice, thick radical and has pushed the seed coat above the potting mix. On 12-29-19, moved the 3 germinated sinkers to the milk jug of potting mix. The oldest one didn't seem to be progressing in water. It might have if I'd left it alone, but I couldn't stand it.

As of 1/8/20, all 20 seeds had emerged. The 3 that I left in the water until 12-29-19 were the last to emerge.
MrsBinWY On December 14, 2019 Seeds sown
16 seeds from maxx2's 2019G in milk jug @ room temp. Floated the rest (probably ~4 viable - 4 floaters & 4 sinkers) as a test, since the seeds remind me of Amaryllis seeds).
