Have to dig my files out to answer.....
Mikado is an art form from Japan. Plant grouping together of cut spears.
The two types mostly used for Mikado arraignments are Sansevieria Fernwood ( A hybrid produced by Fernwood Nurseries in California, one parent being gracilis. Dark cylindrical arching leaves with close to the soil runners producing offsets) and Sanseveria cylindrical.
As stated above they are leaf cuttings and will root and produce off shouts which will not look like the leaves they came from. Common for the juvenile leaves not to resemble the mature leaves in a lot of species. But they will eventually will look like the mature leaves in later new growth.
Bottom plant looks to be a dwarf S. cylindrical called 'Boncel'.
Sanseveria are Monocarpic. Monocarpic plants are those that flower, set seeds and then die.
The raceme (flowers) of Sansevieria is derived from the apical meristem and a flowered plant will no longer produce new leaves. Unlike plants such as agave which die after flowering, Sansevieria will simply cease to produce new leaves. The flowered plant will continue to grow by producing plantlets via its rhizomes or stolons. (

The Splendid Sansevieria by B. Juan Chaninian pg. 16
"After flowering, sanseverieas do not grow any further, but are guaranteed to produce new growth by means of rhiizomes or stolons. Once flowered, unlike other genera, the plant does not die. It will die, provided a long time is given. One can hardly say the plant is dying when leaf cuttings taking from it produce new offsets, or when, if severed from all new growth, it will still offset new plants".
