Silken, buttery leaves unfurl in a luminous rosette, offering a crisp-yet-gentle crunch with a sweet, clean finish. Flashy Butter Gem forms a compact butterhead at about 50 days, with tender, spoon-soft texture that stays pleasantly mild as it matures.

Frequently Asked Questions

Lactuca sativa (lettuce) — what pest or disease issue should I watch for, and how do I fix it?

Watch for downy mildew (often shows as yellow patches on leaves with grayish growth underneath) and aphids, which cluster on tender new growth. Improve airflow and avoid wetting leaves when you water; remove and discard badly infected leaves to slow spread. For aphids, rinse plants with a strong jet of water and, if needed, spot-treat with insecticidal soap according to the label.

How often should I water Lactuca sativa during the main growing phase, and what soil moisture level should I maintain?

During active leaf growth (roughly weeks 2–6), keep the soil evenly moist—water when the top 1 inch feels dry. Aim for consistent moisture rather than soaking and drying, because irregular watering can lead to bitterness and premature bolting in lettuce. If you’re growing in hot part-sun conditions, check moisture 1–2 times per week and water more frequently only if the top inch dries out.
