45 days — An old garden standard spinach variety, 'Bloomsdale Longstanding' is an early maturing variety with dark green colored, crumpled leaves. This variety "stands well," that is, it does not bolt as fast in hot weather, and therefore can be sown in spring or fall.
'Bloomsdale' spinach was originally released by D. Landreth & Company
in the 19th Century. "Bloomsdale" was the name of Landreth's farm in Bristol, Pennsylvania which they moved to in 1847. 'Long Standing Bloomsdale' is an old improved variety selected for its slow bolting trait and introduced in 1925 by Zwaan and Van der Molen, Voorburg, Netherlands.
According to the USDA, 'Bloomsdale Longstanding' spinach has also been marketed over the years by various seed suppliers using the following synonyms:
'Aristocrat', 'Bloomsdale Improved Long Standing Thick Leaved', 'Bloomsdale Long Standing', 'Bloomsdale Savoy Long Standing', 'Burlington', 'Late Seeded Bloomsdale', 'Hot Weather', 'Late Seeding', 'Long Standing Bloomsdale', 'Long Standing Savoy Leaved', 'Keselected Bloomsdale Long Standing', 'Special Summer Savoy', and 'Summer Savoy'. Although 'Summer Savoy' is reputed to be slightly flatter in habit than 'Long Standing Bloomsdale', no consistent difference could be detected in the stocks tested.
Each packet contains four grams, which is approximately 300 seeds.
