About Bloomsdale Spinach

Spinacia oleracea 'Bloomsdale' · also called Bloomsdale Spinach, Bloomsdale Long Standing Spinach · edible

A heritage open-pollinated spinach prized for its thick, crinkled (savoy-type) dark green leaves and excellent bolt resistance compared to flat-leaf varieties. Matures in 45–50 days. Rich in iron, vitamins A and C. Grows best in cool seasons; slow to run to seed, making it a reliable choice for late-spring and early-autumn harvests.

Mature size: 20–30 cm (8–12 in) tall, 20–30 cm (8–12 in) wide

Indoor size vs how big it gets in the wild

Bloomsdale Spinach is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem. Indoors and in a pot, expect 20–30 cm (8–12 in) tall, 20–30 cm (8–12 in) wide. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Bloomsdale Spinach is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: work a balanced granular fertiliser (5-10-10) into the soil before sowing. liquid nitrogen feed every 3 weeks promotes dark, lush growth. avoid heavy feeding late in the season as it can encourage soft, disease-prone leaves.

Want this turned into the right next pot at the right moment? The pot size calculator and the bloomsdale spinach repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast bloomsdale spinach grows.

How to keep bloomsdale spinach smaller

Good news — bloomsdale spinach barely needs managing. If you do want to keep it tidy:

Divide or remove offsets when the pot looks crowded to keep bloomsdale spinach to a single tidy clump.
Keeping it slightly pot-bound and easing back on feed naturally caps the size.
Pinch or remove the oldest, tiredest leaves so energy goes into a compact, fresh-looking plant.

How to grow bloomsdale spinach bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for bloomsdale spinach the accelerators are:

It is already in good light; consistent warmth and a balanced feed in spring and summer are the only levers.
A small step up in pot size every couple of years gives the roots a little more room without triggering a size jump.
Feed lightly through the growing season; this plant simply will not race however hard you push it.

Light is almost always the ceiling. The bloomsdale spinach light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When bloomsdale spinach outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for bloomsdale spinach:

Roots circling the bottom or pushing out of the drainage hole — it wants a pot one size up, not a bigger room.
Offsets crowding the surface so the original plant looks squashed.
Honestly, bloomsdale spinach rarely outgrows a room — outgrowing its pot is the only realistic limit.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the bloomsdale spinach repotting guide. If you want more of this plant instead of a bigger one, the bloomsdale spinach propagation guide turns prunings into new plants.

Bloomsdale Spinach size — frequently asked questions

How big does bloomsdale spinach get?

Bloomsdale Spinach reaches 20–30 cm (8–12 in) tall, 20–30 cm (8–12 in) wide when grown indoors. It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Is bloomsdale spinach slow or fast growing?

Bloomsdale Spinach is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Bloomsdale Spinach is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem.

How long does bloomsdale spinach take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
