Waxed vs Potted vs Vase Amaryllis: Which Kit to Buy

Waxed, potted and vase amaryllis all flower the same way: the bulb already holds this season’s flower stalk and the energy to grow it, so warmth and moisture just let it out. The difference is what happens after the bloom. A waxed amaryllis has no roots and no soil, so it spends its reserves and is done for one season. A potted amaryllis kit can grow leaves after flowering, refill the bulb, and bloom again next year. A glass vase sits in between: a striking display, but water-grown bulbs do not always perform as well as bulbs in soil. Buy waxed for a no-care gift, potted if you want to keep the plant.

TL;DR

An amaryllis bulb sold for forcing already contains its flower stalk, the scape. Every format will bloom once if the bulb is good.
Waxed amaryllis: zero care, one season. The wax blocks roots, so the bulb cannot rebuild what the flowers spend.
Potted amaryllis kit: the only format set up for a rebloom, because roots in soil let the leaves refill the bulb after flowering.
Glass vase: only the roots should touch the water or the bulb rots, and you supply the bulb yourself.
Kits flower about 4 to 8 weeks after planting. For Christmas blooms, plant by early to mid November.

What is actually inside an amaryllis bulb

An amaryllis bulb is a storage organ. By the time it reaches a store shelf, the flower stalk for this season is already formed inside it, a point University of Missouri IPM makes plainly: warmth and moisture only make the scape grow, they do not create it. That is why a bulb with no soil at all can still flower. Everything the first bloom needs is packed into the bulb before you buy it.

The second half of the mechanism is the energy bill. Flowering spends the carbohydrates stored in the bulb, as Iowa State Extension explains. A bulb that blooms without any way to make new food comes out of the season smaller and weaker than it went in. The only way to refill an amaryllis bulb is leaves in light, fed through roots in a growing medium. Hold that one fact and the three formats sort themselves.

Bulb size matters for the same reason. More stored energy means more to spend. Clemson’s Home and Garden Information Center notes that bigger amaryllis bulbs give more stalks and bigger flowers: a bulb of 30 to 32 cm circumference typically gives two stalks, and larger bulbs up to three. When a listing names a bulb size, that number is the closest thing on the label to a promise about the show.

Waxed amaryllis: a one-season bloom

A waxed amaryllis is a bare bulb dipped in a sealing coat of wax, usually with a small stand or wire base so it sits upright on a table. You never water it. The stored reserves push up the scape, the flowers open, and the bulb does all of that on what it already holds.

That convenience is also the whole limitation. A waxed amaryllis bulb cannot grow roots while the wax is on, so it has no way to take up water or nutrients and no way to rebuild what flowering spent. Iowa State Extension describes the result: the bulb shrinks and may be too spent to recover. Clemson’s Home and Garden Information Center is blunter. Waxed bulbs have enough stored energy to flower for one season and are meant to be discarded afterward.

A rebloom is possible but not guaranteed. The University of Delaware and Iowa State both describe the same attempt: cut the wax off from the base of the bulb, then root it and pot it in a growing mix. Treat that as a long shot. The bulb starts its recovery already depleted, with no roots, at the point where a potted bulb would already be refilling.

Buy waxed when the goal is a single season of flowers with no watering, as a gift for someone who will not want a pot of soil on the table, or as a centerpiece you plan to throw out once the flowers fade.

Potted amaryllis kits: the only format built for next year

A potted amaryllis kit gives you a bare bulb, a pot and a bag of growing mix. Planting follows the extension guidance. Clemson’s Home and Garden Information Center recommends a pot 1 to 2 inches wider than the bulb, with a third to half of the bulb sitting above the mix. Water once thoroughly, then wait about a week before watering again. Growth starts slowly while roots form, and that first wet spell is when an overwatered amaryllis bulb can rot. A dense, constantly wet mix is the risk, the same mechanism as a perched water table in the bottom of a pot.

Clemson puts flowering at about 4 to 8 weeks after planting. While the scape is growing, 70 to 75 F suits it; once the flowers open, a cooler 65 F room prolongs them.

The reason potted wins for keepers is what comes next. After flowering, cut the spent stalk and keep the leaves growing in light with regular feeding, the stage where feeding the plant through healthy soil pays off. Those leaves are the factory that refills the bulb. Clemson, University of Missouri IPM and Iowa State all describe the same cycle from there: after a season of leaf growth, an 8 to 10 week dry rest sets up the next bloom. A waxed bulb never gets the leaf season, which is the whole difference between the two formats.

Amaryllis in a glass vase

Forcing an amaryllis in water uses a vase with a narrow waist that holds the bulb above the water while the roots grow down into it. It looks great on a windowsill because you can watch the roots, and it skips soil entirely.

The water level is the one rule. UC master gardeners note that only the base and roots should touch the water; if the bulb itself sits in water, it rots. Top the vase up as the roots drink, but keep the bulb’s base just above the waterline.

The trade-off is in the same UC publication: water-grown amaryllis do not always perform as well as soil-grown ones. A bulb that blooms on its stored reserves will still flower in a vase. Refilling the bulb afterward is harder without a growing medium, so if you want a rebloom, plan to move the bulb into a pot of mix after flowering.

Which amaryllis kit to buy

Decide on one question first: do you want this amaryllis next year?

Buy a potted amaryllis kit if yes. It is the only format where the bulb can grow leaves in soil after flowering, refill its reserves, and take the 8 to 10 week dry rest that sets up another bloom. It also asks the most of you: watering, light and feeding through the leaf season.

Buy a waxed amaryllis if no. It needs nothing, it flowers once, and the extension guidance is clear that it is meant to be discarded afterward. As a gift for someone who does not grow plants, that is a feature.

Buy a glass vase if you want the display and already have, or will buy, a good bare bulb. The vase is reusable year after year; the bulb in it behaves like a one-season bulb unless you pot it up afterward.

Whatever the format, check the bulb size when the listing gives one, since bigger bulbs mean more stalks. Then count back from the date you want flowers: with 4 to 8 weeks to bloom, plant by early to mid November for Christmas.

What to buy

The three products below were chosen to match the spec in this article: one of each format, with a large bulb where a bulb is included. They were not compared hands-on, and this is not a test of one brand against another. Bulb size varies by batch and season, so check the listing before you order.

Amaryllis Growing Kit: Red Lion bulb, plastic pot, saucer and growing mediumAmazon
The potted format, and the one to buy if you want to keep the plant. Honest caveats: you must water it, and the bulb can rot if you overdo it before roots form; kit pots and soil vary, so if the included mix looks dense, a better-draining mix is worth swapping in.

Red Base Waxed Amaryllis Bulb with StandAmazon
The waxed format: no watering, one season of flowers. Honest caveats: it is a one-season bulb by design; it cannot root with the wax on; and the wax means it is not compostable as is, so plan on the bin rather than the compost pile.
View on Amazon
Seeded Glass Amaryllis Bulb Vase, ClearAmazon
The vase format, a reusable glass forcing vase in seeded (lightly bubbled) glass. Honest caveats: it is a vase only, so you still need to buy a bare bulb separately, and the listing does not state which bulb size it fits, so check the opening against your bulb; and water-grown amaryllis do not always perform as well as soil-grown ones.

FAQ

Can a waxed amaryllis bloom again?

A waxed amaryllis can bloom again, but it is a long shot. The wax stops the bulb from growing roots, so flowering spends reserves it cannot replace. To try, cut the wax off from the base, root the bulb and pot it in a growing mix. Clemson’s Home and Garden Information Center describes waxed bulbs as meant to be discarded after one season.

How long does an amaryllis kit take to bloom?

An amaryllis kit typically flowers about 4 to 8 weeks after planting, according to Clemson’s Home and Garden Information Center. Keeping the amaryllis at 70 to 75 F while the stalk grows helps; a cooler 65 F room once it opens makes the flowers last longer.

When should I buy an amaryllis to bloom by Christmas?

Buy the amaryllis early enough to plant it by early to mid November. With about 4 to 8 weeks from planting to flowers, a bulb planted then usually opens in December. A bulb planted in late November or December may flower after the holidays instead.

Does a bigger amaryllis bulb mean more flowers?

Yes. A bigger amaryllis bulb stores more energy, so it gives more stalks and bigger flowers. Clemson’s Home and Garden Information Center notes that a bulb of 30 to 32 cm circumference typically gives two stalks, and larger bulbs up to three.
