Advice needed for new to allium gardener
I've looked through catalogs and have fallen in love with the Gladiator Allium. I want them for cut flowers.
I have a very nice garden spot just waiting for something. :) It's a 12'x 20' and it gets good sunlight...the soil is good, not sandy or clay like. It's very convenient to water too! But I know very little about growing these beauties.
The information that I have gathered from searching is that they do not "spread" on their own. What do I need to do in order to take the first 12 bulbs that I would like to order and turn them into a full fledged garden? My experience is mostly with ornamental grasses and herbs...they spread on their own!
Is there any other Alliums that you would recommend as a cut flower...something showy and out of the ordinary.
Thank you in advance for any help that you might give me.
