Allium cowanii
Related to A. neapolitanum, A. cowanii is a 1823 heirloom prized for its sprays of glistening white floral umbels. Each 2"-wide umbel is comprised of dozens of white florets adorned with ivory-green anthers and pale green eyes (ovaries). Long-lasting and rabbit-, rodent- and deer-resistant, it is ideal in full sun to partial shade, in densely planted borders and rock gardens, forced pots and bouquets. Bulb size: 5 cm/up. May. HZ: 6-9. Height: 16" to 24".
We are very sorry, but due to state agricultural restrictions, we are not permitted to ship Allium bulbs to Idaho or Oregon, or to the following five counties in the State of Washington: Adams, Benton, Franklin, Grant and Klickitat.

Miscellaneous Narcissi
Not to be overlooked, these varieties are in their own little group because they don't quite fit into any of the R.H.S. divisions.
All Narcissi tolerate a wide range of sunlight from full sun to semi-shade. Varieties with pink cups should be grown in areas of filtered sunlight. Narcissi prefer well-draining soil, hate to get wet feet and love to be fed with a 4-10-6 or 5-10-5 granular organic flower bulb fertilizer three times a year. Allow the foliage to thrive and die back naturally without braiding or premature removal. Bulb size: 12/14 cm, unless otherwise noted. Bloom time in a horticultural zone 5: March/April. Plant 6" deep and 6" apart. Horticultural zones 5-8. Height: 6" to 14", depending upon variety. Narcissus classification: Royal Horticultural Society Division 12.
