Hyacinthus spp.(orientalis)

Fully hardy bulbous perennial, which is commonly grown. They must be increased vegetatively because their colour and vigour is the result of years of selection. The easiest way is by division of offsets. However, hyacinths reproduce slowy, so various methods of cutting the bulbs may be used if no offsets are available. The rate of success depends on keeping the bulbs free from rot. Hyacinths are fully hardy in the ground, but frost-tender in containers. New plants flower in two years.

Helleborus orientale

The Lenten rose hybridizes freely, but the seedlings are usually attractive; for true offsprings, plants must be divided (after flowering).
