Plant these astounding alliums in a group to make a bold gesture and watch their completely round purple heads expand as new flowers cover the old throughout summer - keeping a tidy presence
- Position: full sun
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: July
- Hardiness: fully hardy
Large spherical flowerheads made up of numerous star-shaped, deep violet flowers appear in summer. The enormous flowerheads, measuring up to 15cm, look great in pots or borders where they can be seen in their full glory. They are also perfect for a sunny border, dotted in groups among ornamental grasses, or as part of a Mediterranean scheme. Alliums look best planted between medium-sized herbaceous plants that will help to mask the strap-like leaves, which fade by the time the flowers appear.
- Garden care: Avoid excessive moisture from late summer when dormant.

When is the best time to buy and plant these? If I plant them in a container now (this early spring) will they flower this year? Also would you recommend a 2 litre pot per container?
Thank you kindlyAsked on 23/2/2016 by Caz271083 from Nottingham
There is one bulb per 2lt pot which was potted last autumn, so will flower this year as long as planted in a sunny position.
If you want to have a display of these alliums, you will probably want a few of these 2lt pots.

Q:Hi, What stage are these at now it is May. I have some gaps in a run of Globemasters that I would like to fill. Are they actively growing and will flower this year ?Asked on 11/5/2015 by Jon from Manchester
These are in active growth and although we cannot guarantee flowers at any particular time, I would say that there is an excellent chance that they will flower this year.Answered on 15/5/2015 by Helen from crocus
Are these bulbs already potted and growing? It's my friends birthday and she mentioned in the summer how she loved the huge allium flowers. I should have got myself organised earlier and planted some bulbs for her but left it too late so was looking to see if I could find ones already potted for her.

Yes these bulbs are already planted in 2lt pots, although I doubt they will be showing any growth yet.

Q:Allium 'Globemaster' planting
Please can you tell me if it is too late to plant the above bulbs at the end of November. Many thanks ValerieAsked on 27/11/2009 by Valerie
A:Hello Valerie, It is a little late, but if you get them in the ground as soon as possible you should not have any problems. You should enrich the soil with added compost and plant the bulbs 15cm deep. Space them at 25cm intervals to take full advantage of the big flower heads. Make sure the soil does not get too wet or waterlogged over winter. I hope this helps. Helen Plant DoctorAnswered on 30/11/2009 by Crocus Helpdesk
