Looking for something unique and different?  Try this white honeyweed!  It is hardy down to zone 6 and so can be a perennial for those of you in warmer zones, but it can also be grown as an annual as well in colder zones - our first year seedlings, grown from seed, bloomed in year one.  This interesting plant (Leonurus sibiricus 'alba') produces tall, arching flower spikes with white whorls that open up progressively from bottom to top (similar to the way beebalms do).  This selection adds some height (grows about 4-6' high) and interest to the garden!  Prefers sun and well draining soil.  Seed heads also add textural interest.
