Description, &c. — This very pretty little plant is admirably adapted for rock-work, as it produces its bright 
rose-coloured flowers when it is scarcely two inches high, beginning to flower early in spring, and continuing till 
the middle of November. It is a native of Nepal, and was introduced in 1824. It grows best in light sandy 
loam and peat, and ripens abundance of seed.
