Species of endangered flowers that have bloomed in our biotope (May 2021)

The following are endangered flower species that have bloomed in our biotope.
As customary, they bloomed beautifully this year, too.

Salvia plebeian (National and Gunma Prefectural near-threatened species)	Floating heart (National near-endangered species, Gunma prefectural IA endangered species)	Amsonia elliptica (National near-endangered species, Gunma prefectural IA endangered species)
Wild salvia plebeian has been growing in our biotope for over a decade. Classed as a biennial plant, salvia plebeian takes over a year to go from budbreak to bloom. Its flowers are tiny and light purple. Plenty of salvia plebeian are found across our biotope.	Floating heart is a flowering plant that grows in relatively shallow waters, such as ponds and swamps. After some floating hearts were found in Isezaki City in 2011, they were transplanted to our biotope in 2012 for conservation in a stable environment. As customary, their bright yellow flowers bloomed this year, nine years after transplanting.	Amsonia elliptica is another endangered species found in Gunma Prefecture. Like the floating hearts, they were transplanted to the biotope for conservation in 2019. Their stump has grown large over the past three years since transplanting, and as customary, their beautiful light purple flowers bloomed again this year. If they continue to grow healthily, they will bloom again in the fall.
