Grape hyacinth
Plant bulbs in autumn; this is a notably easy-going, drought-tolerant genus once established — one of the lowest-maintenance spring bulbs in the KB, and a good choice for a first bulb-growing attempt.
Care
One of the more drought-tolerant spring bulbs once established.
Free-draining soil of any reasonable fertility; very adaptable, tolerating poorer soil than most spring bulbs.
Not applicable — leave foliage to die back naturally after flowering.
Needs no feeding — it increases quite fast enough on its own, and in many gardens the problem is having too much of it rather than too little.
Lift a congested clump when dormant and pull the bulbs apart; every one will grow. It also self-seeds freely, so thinning and moving is usually more relevant than deliberate propagation.
