The grass seeds I have a question about are:

Jonathan Green Black Beauty Grass Ultra Seed Analysis: Dakota Tall Fescue - 29.55% Montana Tall Fescue - 29.50% Tonto Tall Fescue - 19.65% Madison Kentucky Bluegrass - 9.82% Frontier Perennial Ryegrass - 9.82% Inert Matter - 1.60% and

Scotts KBG Blend Analysis: Jump start kbg -7.31 Gaelic kbg - 14.6 Abbey kbg -14.2 Right kbg -12.2 and 50% Water smart plus fertilizer coating.

My question is: Will the grass seed I bought this year have the same germination potential next year if stored properly (either un-opened or stored in a plastic bag in a cool dry location)?
