How a bulb stores a season

A bulb is a packed bud and a food store, built in one season and spent in the next.

When the purchase is complete, return to the original window. It will refresh.

From the opening

A bulb is an underground store made mostly of fleshy leaves or leaf bases wrapped around a short stem and a bud. The plant fills those scales during the growing season and then uses the store to emerge quickly the next time conditions suit it. The opening covers scales are packed storage leaves, the flower spends last year's store, and green leaves refill the next bulb.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
