Comments about Allium hollandicum 'Purple Sensation':
Good sized firm bulbs. Great for adding colour between the early spring bulbs and the summer perennials. Seem happy on most soils in most aspects and resilient and maintenance free. Only problem so far squirrels digging them out to bury walnuts!

Q:When is it safe to cut off the faded flower stalks of Purple Sensation?Asked on 27/6/2015 by Fifer from Scotland
You can cut them off whenever you like, but I tend to leave my seed heads on for as long as they look good, which is usually in autumn.Answered on 1/7/2015 by Helen from crocus
Q:Why do my Allium leaves get dry and yellow? I watered, but it did not help, And then reduced watering but again it did not help.Asked on 25/4/2015 by KangaTroll from Dorset
The foliage of these plants does not last very long at all, and as the plants energy is diverted into producing the flowers, by the time these open, the leaves are looking pretty tatty. This is completely normal so nothing to worry about, but I would recommend giving the plants a good feed now with a general purpose fertilser.Answered on 15/5/2015 by Helen from crocus
Q:What size pot would be the minimum for these bulbs? I recently purchased a batch of these bulbs from Crocus and have some pots in mind. They are square pots, about 30cm x 30cm x 40cm high. Could I get away with four per pot?Asked on 24/10/2013 by Gregorhanslik from London
Yes these pots should be fine, but I would plant more bulbs per pot, approx a bulb width apart as then they have more impact. Also make sure that they don't dry out during the spring otherwise the flower buds can then fail to open.
Hope this helpsAnswered on 25/10/2013 by Georgina from Crocus
