Invasive Spanish bluebells (Hyacinthoides hispanica), are strong growers that can quickly invade a garden. David Hurrion gives his advice on spotting them, and removing the bulbs from the soil.
Spanish bluebells have much larger flowers, are stronger growing and seed more freely than our native bluebells, which means they can quickly invade your garden. The best way to get rid of them is to fork them out of the soil to remove the bulb, but it will probably take a couple of years to get rid of them completely.
And where they’re growing among shrubs and perennials, it can be difficult to get to the bulbs, so you may have to lift the other plants. Persevere and you’ll eventually get rid of them.
