About vacuum sealing

Why Vacuum-Sealed Seeds Last Longer

Standard paper seed packets are permeable to oxygen and moisture -- the two primary causes of seed degradation. Most paper-packaged seeds begin losing germination viability after approximately one year, contributing to significant garden-industry waste: packets purchased, not planted, expired, discarded. Shido Seeds are hermetically vacuum-sealed. The packet does not expire quietly in a drawer. It waits.

About the Packaging

Every Shido seed packet is illustrated in the style of Japanese 1910s woodblock printing -- designed and drawn in-house by Chive, that has been exhibiting at the Chelsea Flower Show in London every year and does not, as a matter of principle, sell to big-box retailers. Customers collect the packets as a series. This was not the original plan.

Satisfaction Guarantee

We stand by the quality of our flower seed packets! Every Shido seed packet is lab-tested for germination before it ships. If your seeds do not perform to the stated germination rate under correct growing conditions, contact us and we will replace or refund. Guaranteed!

Getting to know your Buttercrunch

Buttercrunch is the Cornell-bred Bibb lettuce that won an All-America Selections award in 1963 and never really left the catalog. The heads are loose and rosette-shaped, with thick, tender leaves and a mild, buttery texture that gives the variety its name. It holds in warm weather longer than most soft-leaf lettuces, though it remains a cool-season crop that does well sown early in spring and again in late summer. Direct sow small batches every couple of weeks, thin to 8 to 12 inches, and cut the whole head at the base once it fills out. It grows as well in a container as in a bed.


History & origin

Kentucky, 1800s

Bibb lettuce, the butterhead type Buttercrunch descends from, comes from a Kentucky garden and is commonly dated to 1865, when John Bibb developed it. It was later named in his honor.

Cornell University

Buttercrunch was developed by George Raleigh, a professor of vegetable crops at Cornell University, as a Bibb-type lettuce that tolerated summer heat better than its parent.

1963 All-America Selections

Buttercrunch won an All-America Selections award in 1963, recognized for its tolerance of heat, poor soils, and bolting, and it has stayed in catalogs since.

Today

Still grown for its loose, thick-leaved heads, buttery texture, and slower-bolting habit.

Step-by-Step Sowing & Growing Guide

Getting Started

Annual, direct sow

Step 1: Timing - Direct sow 2-4 wks before last frost; succession sow every 2-3 wks; sow again in late summer.

Step 2: Soil - Loose, fertile, well-drained, pH 6.0–7.0.

Step 3: Sowing - 1/8-1/4 in deep. Germination takes 4-10 days at 45-75°F.

Step 4: Spacing - Thin or transplant to 8-12 in apart in rows 12-18 in apart.

Step 5: Care - Full sun to part shade; consistent moisture.

Step 6: Harvest - 55-65 days. Buttercrunch holds in heat better than most soft-leaf lettuces, but it is still a cool-season crop — sow early and again in late summer for the sweetest heads.

Before you start

Materials needed to sow

  • Prepared garden bed or seed trays: Lettuce can be direct sown or started in trays; both work.
  • Seed-starting mix: If starting indoors, a fine mix gives tiny seed good contact.
  • Fine-rose watering can or mister: Waters shallow-sown seed without washing it away.
  • Shade cloth or row cover: Extends the season on either end of summer heat.
  • Plant labels: Useful for tracking succession sowings every couple of weeks.

Materials for harvest and storage

  • Sharp knife or scissors: Cut the head at the base for a clean harvest, or take outer leaves one at a time.
  • Basket or bowl: For collecting heads or leaves.
  • Damp towel or produce bags: Wrap and refrigerate straight after harvest to keep the leaves crisp.

Tip: Harvest in the morning when the leaves are cool and crisp, and cut before the center starts to elongate, which signals bolting.

Growth Requirements

Light:

  • Prefers full sun in cool weather and part shade in heat (about 4-8 hours of sun).

Soil:

  • Loose, fertile, well-drained soil, pH 6.0-7.0, with compost worked in before sowing.

Watering:

  • Requires consistent moisture, since lettuce roots are shallow.
  • Water in the morning at soil level; dry spells make leaves bitter.

Temperature & Climate:

  • Grows well in cool weather, 60-70°F. Buttercrunch tolerates warm weather better than most soft-leaf lettuces but still bolts in sustained heat.

Fertilization:

  • Work compost into the bed before sowing.
  • Side-dress lightly with a balanced fertilizer mid-season; excess nitrogen gives soft, leafy growth that rots more easily.

Maintenance

Thinning:

  • Thin seedlings to the final spacing once they have two true leaves, and eat the thinnings as baby greens.

Mulching:

  • A light mulch of straw or shredded leaves keeps soil cool and moist and keeps leaves off the ground.

Succession Sowing:

  • Sow a short row every two weeks in cool weather for a steady supply, and again in late summer.

Watering:

  • Keep soil evenly moist; avoid overhead watering late in the day, which invites mildew.

Harvesting:

  • Cut the whole head at the base once it is full and loose, or pick outer leaves as the plant grows.
  • Harvest in the morning when leaves are cool and crisp.

Storing:

  • Rinse, dry well, and store loosely wrapped in the refrigerator for up to a week.

Troubleshooting and common mistakes

  • Sowing too late into summer: Buttercrunch holds up in heat better than most soft-leaf lettuces, but it is still a cool-season crop; sow early and again in late summer
  • Warm soil at sowing: lettuce seed germinates poorly in hot soil; sow in cooler weather or shade the bed
  • Uneven watering: dry spells make leaves bitter and encourage tipburn

Culinary uses & nutritional information

What it's used for

1. Culinary Applications:

  • Loose butterhead leaves in salads and sandwiches
  • Lettuce wraps, since the thick, buttery leaves hold fillings
  • A base for simple dressings that do not overwhelm the mild flavor
  • Lightly braised or wilted into soups when the harvest runs ahead

2. Nutritional Benefits:

  • Source of folate and vitamin K in typical butterhead ranges
  • Low in calories and high in water content
  • Provides fiber and potassium in modest amounts

3. Garden Uses:

  • Heat-tolerant, slower-bolting Bibb type for succession sowing
  • Compact heads suit raised beds and containers
  • A 1963 All-America Selections winner with a long track record

4. Practical Benefits:

  • Quick to mature, so it fills gaps between slower crops
  • Thinnings double as baby greens
  • Worth planning for: sow early and again in late summer

What parts are edible

  • Leaves: The edible part: loose, buttery heads eaten raw in salads and sandwiches, or tucked into wraps.
  • Thinnings: Young seedlings pulled while thinning work as baby greens.

Companion plants, pests & diseases

Companion planting

Good companions

  • Carrots, radishes: different root depths and little competition; radishes mature before lettuce needs the space
  • Onions, garlic, chives: the scent may help deter aphids
  • Strawberries, cucumbers, tall crops: lettuce tolerates the light shade they cast, which helps in warm weather

Poor companions / avoid

  • Cabbage family (broccoli, cabbage, kale): reported to compete for nutrients and space
  • Celery, parsley: sometimes reported as poor neighbors in tight beds

Pests

  • Aphids: cluster on leaf undersides and in the heart; strong water spray or insecticidal soap
  • Slugs and snails: ragged holes and slime trails, worst in damp weather; handpick or use iron phosphate bait
  • Cutworms: cut young seedlings at the base; use collars around transplants

Diseases

  • Downy mildew: yellow patches with gray fuzz underneath in cool, damp weather; space plants and avoid overhead watering
  • Bottom rot (Sclerotinia drop): heads wilt and rot where they touch wet soil; keep leaves off the ground and avoid crowding
  • Lettuce mosaic virus: mottled, stunted leaves, spread through seed and aphids; remove infected plants and control aphids
  • Tipburn: brown leaf edges, a physiological problem tied to fast growth and uneven watering rather than a pathogen; water evenly

Pro Tip

Direct sow Buttercrunch as soon as the soil can be worked and keep sowing small batches every few weeks. The loose, Bibb-type heads with thick, buttery leaves are ready in about two months and stand longer in warm weather than most soft lettuces.

Bonus: A 1963 All-America Selections winner still grown for exactly the same reason: texture.

Seeds worth keeping

What makes Shido Seeds different

Shido Seeds are designed by Chive Studio, a ceramic design company. We are not a seed conglomerate. We do not sell through big-box retailers. Each variety in the catalog was selected because it is worth growing — not because it ships well in bulk or photographs well in marketing materials.

Every packet is germination-tested at an independent third-party lab before it earns its woodblock illustration. The vacuum seal removes the oxygen that causes standard paper packets to degrade. The stated germination rate is a floor, not a marketing figure.

If something goes wrong, contact us. We will make it right.

Flowers That Never Need Watering

Seeds ask for patience; Chive's ceramic wall flowers are in bloom the moment they are unwrapped, designed in the same studio since 2004.

The credentials behind the packet

Chive Studio started as a ceramics workshop and grew, one collection at a time, into seeds, vases, and everything else now carrying its name. Shido Seeds is the newest branch of that same tree, built on the belief that a seed packet deserves the same attention to material and design as a ceramic vase does. That is why every variety, lettuce included, ships vacuum-sealed rather than paper-packed, and why the packaging is illustrated rather than merely printed.

Frequently asked questions

How do you grow Buttercrunch lettuce?

Direct sow as soon as the soil can be worked, 1/8 to 1/4 inch deep, and thin to 8 to 12 inches apart. Keep soil evenly moist in a spot with full sun in cool weather and part shade in heat.

Is Buttercrunch lettuce heat tolerant?

More than most soft-leaf lettuces. Buttercrunch is slower to bolt in warm weather, but it is still a cool-season crop, so sow early in spring and again in late summer for the sweetest heads.

How long does Buttercrunch take to mature?

Roughly 55 to 65 days from sowing. Baby leaves can be picked sooner, and small batches sown every couple of weeks keep the harvest steady.

What does Buttercrunch lettuce taste like?

Mild and sweet, with thick, buttery leaves and a tender, loose head. The texture is the draw, soft without being limp.

Can Buttercrunch lettuce grow in containers?

Yes. Heads grow 6 to 8 inches tall and 8 to 10 inches wide, so a container at least 6 inches deep with good drainage works, spaced one plant per 8 to 12 inches.

How long do Buttercrunch lettuce seeds last?

Vacuum-sealed Shido Seeds packets stay viable for up to 10 years when stored properly, compared to roughly one year for a standard paper seed packet. Storing unused packets somewhere cool and dry helps preserve that extended shelf life.

Why is Buttercrunch lettuce called a Bibb type?

Bibb is a small, loose-headed butterhead lettuce first developed in Kentucky in the 1800s. Buttercrunch is a Cornell selection built on that Bibb type, with a larger head and better heat tolerance.

Are these seeds lab-tested for germination?

Yes. Every Shido Seeds packet, Buttercrunch included, is germination-tested at independent third-party labs before it ever reaches a shelf.

The seed is the start. Verte RX handles the rest.

Most seedlings fail not from bad seed but from soil that runs out of what the plant needs before the plant can find it. Verte RX is a liquid plant vitamin formulated for exactly that window — the weeks after germination when the root system is establishing and the margin between thriving and stalling is narrowest.
