Allium hollandicum Purple Sensation

Allium hollandicum Purple Sensation – is one of the earliest alliums to flower, normally around The RHS Chelsea Flower Show. It extends the spring flowering season after the tulips are over into summer. No garden would be complete without their striking shape and deep violet-purple colour running in drifts through herbaceous perennials or amongst ornamental grasses.

Like all alliums the bees love them, but they are generally unpalatable to deer; rabbits and squirrels. They will flower year after year and increase by seeding themselves and making this inexpensive and popular flower bulb incredibly good-value.

Plant in full sun for the best results, but keep them watered. All alliums like good drainage but they will perform poorly if they dry out.

More Information

Allium hollandicum Purple Sensation – are perhaps the strongest colour of purple that alliums produce, so it’s no wonder that this mid-sized allium is one of our best sellers. Growing up to 100cm high and producing a head of around 10cm in diameter.

Allium hollandicum Purple Sensation flowers in late spring/early summer, between May and June. They will continue to flower for a couple of weeks. Not forgetting that the allium are a favourite for bees. Read more about the best bulbs for bees>

Broad green leaves will appear long before the flower bud emerges, once the allium is in flower the foliage will start to die back so it is worth trying to hide the foliage amongst shrubs and perennials if you can. Remember that if you want the bulbs to flower the following year you need to leave the foliage, this is so that the leaves can feed the bulb ready for the dormant phase.

How to Plant Allium Bulbs

Alliums are hardy and will flower perennially. You don’t need to lift them although it is good to check on the size of the bulbs during autumn. You can leave in the larger bulbs and take out the small bulblets to prevent them getting crowded.

Plant Allium hollandicum Purple Sensation bulbs in autumn or early winter. Alliums do not like heavy wet soil, needing moist but free draining soil. Add grit if necessary. They don’t perform very well in pots, so plant in the ground in a sunny position. Planting 15-20 cm deep will help to keep the tall flower stable.

Alliums are grown and harvested in the Netherlands although they originated in mountainous regions in Asia. This is why they like hot summers, cold winters and free draining soil.

We sell our Allium hollandicum Purple Sensation bulbs as 10/12 sized bulbs in packs of 10. We are able to offer these in bulk discounts too.

As our latest flowering spring bulb there isn’t much to pair it with from this catalogue. Try planting with early summer flowering flowers such as Bearded Iris, Peonies or Aquilegia.
